What structures are present in an animal cell?
Animal Cell Structure
- Cell Membrane. A thin semipermeable membrane layer of protein and fats surrounding the cell.
- Nuclear Membrane. It is a double-membrane structure that surrounds the nucleus.
- Nucleus.
- Centrosome.
- Lysosome (Cell Vesicles)
- Cytoplasm.
- Golgi Apparatus.
- Mitochondrion.
What are the cytoplasmic structures?
Cytoplasmic organelles are “little organs” that are suspended in the cytoplasm of the cell. Each type of organelle has a definite structure and a specific role in the function of the cell. Examples of cytoplasmic organelles are mitochondrion, ribosomes, endoplasmic reticulum, golgi apparatus, and lysosomes.
What does cytoplasm contain in animal cells?
Animal cell cytoplasm is a gel-like material made of mostly water that fills the cells around the nucleus. It contains proteins and molecules that are particularly important for all cell health. The cytoplasm in an animal cell includes salts, sugars, amino acids, carbohydrates and nucleotides.
What is the main function of cytoplasm in an animal cell?
The cytoplasm functions to support and suspend organelles and cellular molecules. Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis.
What is the main function of the mitochondria in a plant cell?
Mitochondria carry out a variety of important processes in plants. Their major role is the synthesis of ATP through the coupling of a membrane potential to the transfer of electrons from NADH to O2 via the electron transport chain.
What are the main features structures of the animal and plant tissues?
Organs are composed of tissues, which are in turn composed of cells. Plants have three tissue types: ground, dermal, and vascular. Animals have four: epithelial, connective, muscle, and bone….Terms | Back to Top.

What structures is absent in an animal cell?
Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
