Structure of an animal cell
Cells are small units forming living things. People began to know about the cells and their structure after the finding of a microscope.
Every living being have cells, so do the animals.
Animal Cells cytoplasm organelles where important events such as feeding and evacuation, respiration of cells are realized.
The Animal cell organelles are the following:
- Endoplasmic reticulum;
- Plastids and Golgi apparatus.
These organelles may not all be in a reaction cell. Or some organelles may have increased or decreased in number, depending on the type of cell. Now, let’s look at each of them.
- Cell membrane
It is the most basic structure for the cell to exist; It keeps the cell plasma together.
It is a gel covering the inside of the cell.
It is the center of the management of a cell. It contains chromosome structures.
It is a place where energy reactions occur in the cell and it has a double-layered dice.
Common organism in all cells; synthesizes protein.
It is an organelle that provides intracellular digestion.
- Golgi Apparatus
Has a function of secretion work in a cell. Numbers of Golgi apparatus in secretion areas such as saliva and tear glands found in animals have increased.
- Endoplasmic reticulum
It is an organelle of the intracellular organization. It is divided into two groups: with and without a granule. It plays an active role in substance transmission.
Works in animal cell division process.
It forms the cell’s skeleton.
Since we’ve learned about the structure of an animal cell, now let’s have a look at animal cell features.
The features of an animal cell
The features of cells are divided into two main categories: structural and functional ones.
Structural features of an animal cell are the following:
- Genetic information is stored in DNA and genetic code is generally the same;
- Proteins are made by ribosomes and they regulate the function and structure of the cell;
- Plasma cells are surrounded by a plasma membrane which is a selective permeable membrane.
Functional features of a cell are the following:
- Cells receive raw material from the environment;
- They produce Energy and this energy is necessary to provide the internal environment balance, and to carry out the synthesis reactions;
- They synthesize their own molecules;
- They grow up in an organized way;
- They increase (except for some).
Types of animal cells
Animal cells can have many different characteristics in shape, function and size. For example, the difference between a nerve cell and a red blood cell is quite large. These cells are different in shape, structure and task. There are many cells specialized in the body.
Some of them are:
- Stem cells
- Blood cells
- Fat cells
- Sex sells
- Nerve cells
- Cartilage cells
- Epithelial cells
- Muscle cells and others.
Differences between the plant and animal cells
There are some differences between the cells of animals and plants. These differences are the following:
- Cells of a plant have an angular structure, they have a cell wall, they contain chloroplast and they are big.
- Animal cells on the other hand have a round shape, they do not have a cell wall, vacuoles in them are numerous and small, and they do not contain chloroplast.
- Although there are differences between plant and animal cells, all the cells are composed of three main parts: cell wall, cytoplasm and nucleus.
We hope you have gained the information about animal cell features necessary for you and with the other information in this article, you’ve worked your zoology muscles out!
