Difference between Cytokinesis in Plant and Animal Cells Now the main difference between cytokinesis in plant and animal cell is, plant cells have a cell wall that needs to be split while animals do not have any cell wall. In animal cell, a cleavage is formed first of all in the middle of the cell that has to be divided, the cleavage deepens until it meets the membrane and then eventually cell divides. While in plant cells, a row of vesicles develop during cytokinesis.

Difference Between Humoral and Cell Mediated Immunity • Humoral immunity is mediated by B-cells while cell-mediated immunity is mediated by T-cells. • In the humoral immunity, the B-cells secrete antibodies whereas in the cell-mediated immunity, the T-cells do not secrete receptors.T-cell receptors are bound to the T-cells and the cells themselves bind with antigens. The antibodies are used in the humoral immunity whereas the receptors are used in the cell-mediated immunity to defend against pathogens. • Unlike in the cell-mediated immunity, the antigens are destroyed by B-cell antibodies outside the B-cells in the humoral immunity.

What Is the Difference Between Plant Cells Vs. Animal Cells? Plant cells differ in structure from animal cells in that they have a cellulose wall that braces their plasma membranes. Animal cells lack this wall and therefore move with less difficulty than typical plant cells. Plant cells are eukaryotic, just as animal cells are, so both have a discrete nucleus.

- The average size of an animal cell is ~10 to 50 microns (a micron is 10^-6 meter). A cheek cell would fall apx. in that range, probably 30-50 microns. Cell size varies greatly in multi-cellular animal cells, though--the egg cell size of some animals is quite a bit larger--think of an ostrich egg, which is a single cell.

Onion cells Onion cells. 1  1. ONION CELLS. 2  2. ONION PLANT This is what a whole onion plant looks like. We will be looking at cells from the onion bulb. 3  3. Copy CELL WALLPlant cells have cell walls.• Cell walls are made up of cellulose.• They protect the cell.• Maintains the cells shape.• Prevents excessive water uptake. When staining your onion cell, you will need to wait a minute or two before viewing it under the microscope. The stain can take some time to sink in to the cells because of the barrier that the cell wall creates.

Red Onion Cells BRIEF DESCRIPTION. In this simple experiment, students will prepare slides of red onion cells to be viewed under the microscope. Onion cells are easily visible at medium magnification. Their plasma membrane and cytoplasm can be clearly distinguished, and, if a stain is used, their nuclei can be seen, as well. Students will also observe that the cells are uniform in shape and size. This is a consequence of mitotic cell division—which produces genetic clones and contributes to the development of specific tissues, each made up of distinct cell types with distinct functions (in this case, inner epidermal cells).

What is the difference between an animal cell and a blood cell? perhaps that could be your difference. a RBC is a type of animal cell, and animal cell is not a type of RBC. OK, so a more obvious difference would be that most standard animal cells have nuclei were as RBCs do not. or RBCs have hemoglobin, other animal cells do not.evel-an animal cell is eukaryotic whereas a red blood cell is prokaryotic which basically means an animal cell has a nucleus and a red blood cell doesnt but it sounds really smart :D. chips · 7 years ago.

-   3) Root tips have very rapid rate of mitosis.   4) The cells are very responsive to staining techniques.   5) The chromosomes are large and fewer in number. (Only 16 in a  cell have the diploid condition. The reason for mitosis occurring most commonly in the onion root tip is because the onion root tip is a rapidly growing area of the plant. + 2 others found this useful. Jada Nneji.

- Magnified view (400x) of squamous epithelial cells from the buccal mucosa (cheek cells from inside the mouth). The cells are stained with a dye called methylene blue. The nucleus and cell membrane are clearly visible. Plant structures such as a cell wall, chloroplasts and large central vacuole are absent. Because they don't have a rigid (firm) cellulose cell wall, these cells are flimsy and irregular in shape, unlike the rectangular shape of the onion cells. Although they were photographed in fall of 2001, these cells actually came from a student in a previous biology lab three years before.

Do human cheek cells have cell walls? Why or why not? As in all animal cells, the cells of the human cheek do not possess a cell wall. Acell membrane that is semi-permeable surrounds the cytoplasm. Unlike plant cells, the cytoplasm in an animal cell is denser, granular and occupies a larger space. The vacuole in an an animal cell is smaller in size, or absent.

Onion Epidermal Cells vs. Human Epithelial Cells Cell Surface. While both onion and human cells have a cell membrane, only the onion has a cell wall. Both plant and animal cells, including human epithelial, and onion epidermal cells have a structure called a cell membrane or plasma membrane. This membrane holds everything in the cells and is comprised of a phospholipid bilayer, a structure made of oily molecules, held together by the interaction of these molecules with water.

Difference Between Humoral and Cell Mediated Immunity Humoral vs Cell Mediated Immunity. Immunity is the ability of an organism to defend against pathogens and toxins and to avoid infections and diseases. This is basically provided by the immune system, which is composed primarily of individual cells spread throughout the body, rather than forming into organs. The antibodies are used in the humoral immunity whereas the receptors are used in the cell-mediated immunity to defend against pathogens. • Unlike in the cell-mediated immunity, the antigens are destroyed by B-cell antibodies outside the B-cells in the humoral immunity.

Red Onion Cells Optional: Staining Nuclei. 1. After placing onion cells on slide (and before adding the cover slip), put on ONE drop of “Fast Green” or methylene blue stain directly on top of the onion slice. 2. For elementary school kids, teacher should handle the stain (as it is a potential skin toxin).
