Similarities and differences in cell structure, what cells are different from

Structurally more or less the same.

Animal cells do not have a cell wall, whereas plant cells do. Plant cells are also unique to chloroplasts and centrosomes.

The above-mentioned plant cell - broad bean... There are no chloroplasts but there are centrosomes and cell walls.

When human blood cells – red blood cells – are structurally identical to other body cells when they are immature, and when they mature, all organelles and nuclei disappear – leaving only a few substances such as hemoglobin.

Bovine nerve cells, dog skeletal muscle cells – skeletal muscle cells have a higher mitochondrial content than other cells.

For the rest, there isn't much difference.

The landlord can simply remember.

As long as it is an animal cell, there is no cell wall.

But plants must have cell walls.

The cells of the plant class that you are talking about have chloroplasts vacuoles but none of them have centrosomes.

You said that animal cells have centrosomes.

That's pretty much it.

The cells of humans, cows, dogs, and frogs belong to animal cells, and have centrosomes, no cell walls, chloroplasts, and vacuoles;

Some cells of the lower epidermis of broad bean leaves and plant mesophyll cells have chloroplasts, vacuoles, cell walls, and no centrosomes.

The morphology is definitely different, secondly, higher animal cells do not have cell walls, chloroplasts, large vacuoles, higher plant cells do not have centrosomes, and finally, different cells have different functions and the number of organelles is also different.

Tissue.

It is a group of cells and interstitium that are normally similar in shape and functionally identical, and are called tissues. The tissues of the human body are divided into four types: epithelial tissue, connective tissue, nervous tissue, and muscle tissue.

Cell differentiation produces different cell populations, each of which is composed of many cells with similar morphology, structure and function, and interstitial cells, which are called tissues.

Cell groups composed of cells with similar morphology, structure and function constitute tissues, such as muscle tissue, epithelial tissue, nervous tissue and round connective tissue of animals, and protective tissue, vegetative tissue, meristem and conductive tissue of plants.

Cells have different morphologies, structures, and functions. There is no universal definition of cell, but the more common formulation is that cell is the basic structural and functional unit of living organisms.

It is known that all organisms except viruses are composed of cells, but the life activities of viruses must also be reflected in cells.

Cells have different

1. Morphology: For example, the same human body cells, nerve cells have long protrusions, muscle cells are spindle-shaped, and red blood cells are concave on both sides.

2. Structure: For example, eukaryotic cells have complex organelles, while prokaryotic cells have only mitochondria, animal cells have no cell wall, and plant cells and bacterial fungal cells have cell walls.

3. Function: For example, nerve cells have the effect of receiving and transmitting excitation, muscle cells can contract, and red blood cells can transport oxygen.

Morphology refers to the shape and posture of the cell, including whether the cell is flat and three-dimensional.

Spherical or star-shaped.

Whereas, structure refers to the structure and organizational form of the cell, such as this cell has chloroplasts.

That one doesn't, this one has microvilli and that one doesn't.

Cells with the same structure are not necessarily the same in morphology, such as various somatic cells.

The structure is similar, but the morphology is very different. The same are epithelial cells.

There are different morphologies of epidermal and dermal cells.

Morphologically similar structures are not necessarily the same.

Morphology and structure determine the function of cells, and we consider cells with the same morphological structure and function as a group.

It's called an organization.
