Structure of animal cell
- this is the outermost boundary of an animal cell, also called the plasma membrane.
- However, in plants and bacteria, the cell membrane itself is surrounded by a cell wall.
- cell membranes are composed of lipids and proteins (lipoproteins). a cell membrane is or semi-permeable.
- The cell membrane regulates the selective movement of molecules into and out of the cell. it allows certain molecules to pass through it while others can not pass through it.
- Cell membrane takes in material including in the form of vacuoles. it is called endocytosis.
Also Read: Plant cell CYTOPLASM
- it is a vicious opaque (translucent) fluid portion of the cell which is present between the cell membrane and nuclear membrane.
- it consists of an aqueous ground substance called cytosol and a granular portion called cytoplasmic organelles.
- it is composed of organic compounds such as proteins, carbohydrates, lipids, (fats), enzymes, and some inorganic compounds e.g. water and salts.
- some important cytoplasmic organelles found in eukaryotic cells are as under.
- Endoplasmic reticulum
- Golgi complex
- Plastids (in the case of plant cells)
