Mitosis is the process through which the animal cell is duplicated and divided. The process is the base of the development and growth of each organism. The duplication and the division of the animal cell leads to the enlargement of the body functions and therefore to the whole evolution of the system. The animal cell diagram mitosis is one of the most important parts of the learning process. It is used in academic studies and in educational programs in order to help the students understand the processes that take place inside an organism. The methods through which the teachers can present the animal cell diagram mitosis have greatly evolved over the past few years. Modern technology made it easy for them to represent the changes of the animal cell diagram mitosis through animated files.

During the animation of the animal cell diagram mitosis, the students will be looking at a simple process, which takes place over the course of several stages. These are very important, as they each stand to represent an important part of the process, without which the entire evolution would not take place. The fist stage of the animal cell diagram mitosis is the Interphase, during which the DNA is replicated. The Prophase is the second step, which refers to the condensation of the chromosomes, the dissipation of the nuclear envelope and the division and movement of the centrioles. The Promethaphase is based on the the division of all the remaining elements of the animal cell diagram. The Metaphase revolves on the alignment of the chromosomes. Then, these separate during the Anaphase. Lastly, in the Telophase, the chromosomes migrate to the opposite ends and the cell splits in two different new ones.

The process of the mitosis can be very valuable for the proper understanding and learning of the animal cell process. With the help of the animal cell diagram, these processes are more facile, more easy to grasp and all the developing stages can be seen properly. It is important for teachers to find the right animal cell diagram through which to represent the mitosis in the perfect way.

As everyone know, a cell is the basic unit of all the living organisms. No matter how big or small an organism is, it is surely made of cells. For students, in order to understand better what a cell is, teachers use a cell diagram. Thanks to a cell diagram, they can see with their own eyes how a cell looks and they can memorize easily all the details related to it. The human body has a lot of different types of cells and for each and one of them, it is possible to find a cell diagram to make you learn better about it. The lacrimal gland cell, the one responsible with the tear secretions, can also be easily represented through a cell diagram. There are in fact paired glands, as each eye has one and they secrete that layer that covers the eyes, the tear film.

These glands are located in the orbits, each one in its lacrimal fossa that the frontal bone forms on the face. A lacrimal gland cell is also named tubuloacinar, because it is made of many small lobules connected through tissue. All the lobuls contain acini and these acini are responsible with producing a water secretion. All the acini contain central lumen and these form the interlobular ducts. Seeing a lacrimal gland cell diagram is much easier to understand, because the information is reproduced through an image.

The cell diagram is very important when learning about all kind of cells, not only about this one. This is a more particular case, because it describes the eye and it is really simple to understand the information when having a cell diagram as a visual aid. With the help of the lacrimal gland cell diagram, all the designations are paired with images and learning them is not that difficult. All the biology students use a cell diagram every time they need to remember various information about all types of cells. As they are compelled to learn a lot, visual aids are very important and a cell diagram is more than welcomed when studying about the lacrimal gland cell or any other type of cells.

The nervous system is one of the most important parts in our bodies and we would not be able to function without it. This is why it is important to learn something about neurons, which are the nerve cells composing the nervous system. Neurons are cells which are adapted to receiving and transmitting information, being at the same time the elementary, embryologic, anatomic, functional, trophic and metabolic cells of the nervous system. Neurons are therefore electrically excitable cells with the purpose of transmitting and processing information via electrical and chemical signaling. As to any cell, the neuron cell diagram is very important for its better understanding.

The neuron cell diagram typically contains the cell body (also known as the soma), dendrites, and an axon. The cell body is the largest and main portion of the cell, the one which contains the nucleus. The nucleus is usually singular, large and centrally positioned. Here is where a large quantity of ARN is being produced and also where the chromatin is being dispersed. Dendrites are the neuron extensions which look like branches and extend from the cell body. This is not shown in the neuron cell diagram, but dendrites are the one which carry nerve impulses from adjacent neurons into the cell body. Only one extension sets itself apart from the others, which is the axon. The axon arises from the cell body at the axon hillock and can be very large in length (up to even 1 meter).

The axon ending is, as the name and the cell diagram suggest, the very end of each axon. It is also known as the axon terminal, the bouton, the axon foot or the synaptic knob and it has the role of converting the electro-chemical signal into a chemical message which travels further to the next neuron. As to any animal cell, the neuron cell is surrounded by a plasma membrane. The last element in the neuron cell diagram is the myelin sheath, which consists of fat-containing cells that have the part of insulating the axon from electrical activity. The cell diagram of the neuron is surely easier to understand now, isn’t it?

Euglena Cell Diagram

Filed under: Cell Diagram - 02 Apr 2012  | Share on :

Euglena is a genus of unicellular flagellate protists. There are many Euglena species which live both in fresh and salt waters. The most used Euglena species for scientific purposes is called Euglena gracilis. This unicellular flagelate includes chloroplasts in the body of the cell, being able to feed by autothrophy like plants, but also like animals, heterothrophically. As Euglena has both features from animals and plants, it was very difficult to be classified at the beginning. It is composed by a red eyespot, an organelle  with carotenoid pigment granules. It does not have a wall cell, but a pelicle made up of a protein layer and microtubules. These important features make Euglena be very flexible and contractile. When there is not enough moisture, Euglena forms a wall around it and then lies dormant until the environment will get back to normal.

After being seen under the microscope, it was possible to conceive a cell diagram. A cell diagram can be different, depending on each species of Euglena. In time, better descriptions were given and people had the opportunity to see the new discoveries through a cell diagram. Several things were added to an Euglena cell diagram throughout time as new things were discovered.

Euglena cell diagram is different depending also by its colors, components and the way it feeds. There are many types of Euglena cell diagram taking into consideration also the species. Scientists did a lot of research to discover new things about Euglena and each new thing was added into a cell diagram. Euglenas are considered mixothrops: heterothrops in the dark and autothrops  in the sunlight. Although it does not have cell walls, there are pellicles formed from protein bands which lie beneath the plasma membrane of Euglena. It reproduces asexually by fission and life spans are different for each group. The cell diagram shows the main components of it such as flagellum, which is important for mobility, photoreceptor, contractile vacuole, nucleolus, nucleus, stigma or eyespot, polysaccharides and chloroplast.

The skin is the largest external organ, very important for many process, the most known being that of eliminating toxins through perspiration. The skin of an adult occupies a large area and is made up of epidermis, basement membrane zone, dermis and subcutaneous tissue. These layers have different structures depending on the area of the body. Studies have shown hat each square centimetre of skin has 6 million cells, 15 sebum glands, 5 hairs, 2 heat receptors, 12 cold receptors, 100 sweat glands, as well as 400 cm nerve fibres and 100 cm blood vessels. The epidermis is a semi-permeable barrier, having a layer of flat and anuclear cells at the surface, which is called stratum cornum.

A cell diagram shows how the epidermis regenerates through the division of keratinocytes. A keratinocytes cell diagram shows very well how these protein cells are arranged in layers above the basal layer. Analyzing carefully a keratinocytes cell diagram, we can observe how new keratinocytes are made by new divisions. A keratinocytes cell diagram makes obvious how these cells in the basal layer are pushed upwards the surface of the skin. This means they start to flatten and they die. In a keratinocyte cell diagram is pictured how these cells reach the stratum corneum, exfoliate and then die. The process is called skin renewal and takes place very often and lasts around 30-40 days to complete. A cell diagram can show this process or simple the keratinocytes structure. Through this renewal process, the skin is able to optimize its protective barriers and stay safe for all our lives. Keratinocytes are derrived from ectoderm and produce proteins (keratin), as well as lipids.

Using a cell diagram can make obvious how these cells express adhesion molecules and produce inflammatory cytokines. These cells are polygonal, but will become flat at the surface, having irregular dark keratohyalin granules and thin homogeneous eosinophilic area. Their cytoplasm contains keratin filaments. A cell diagram is always useful as it makes easier to understand the connections between many and very tiny components in a cell. Learning using a cell diagram is very helpful and it takes a shorter time to understand the connections.
