explain animal cell with structure |
|
Answer» Animal cells are a typical eukaryotic cell with a membrane-bound nucleus with the presence of DNA inside thenucleus. They also comprise of other organelles and cellular structures which carry out specific functions necessary for the cell tofunctionproperly. The Animal cell is smaller than theplant cellwhich varies in their sizes and is irregular in shape. It comprises of the following parts: Cell Membrane:Athin semipermeable membrane layer of protein and fats surrounding the cell. It helps in owning the cell together and permits entry and exits of nutrients into the cell. Nuclear Membrane:It is the double membrane that surrounds the nucleus. Nucleus:A celestial body containing several organelles including the nucleolus. It contains DNA and other cell’s hereditary information. Centrosome:Itis a small organellefound near to the nucleus which has a thick center and radiating tubules. The centrosomes are where microtubules are produced. Lysosome(Cell Vesicles):They are round organelle surrounded by a membrane comprising of digestive enzymes which help in digestion, excretion and in cell renewal process. Cytoplasm: Ajelly-like double membrane organelles found outside the cell nucleus in which the organelles are located. Golgi Body: A flat smooth layered, sac-like organelle which is located near the nucleus and involved in manufacturing, storing, packing and transporting the particles throughout the cell. Mitochondrion:They are spherical to rod-shaped organelles with a double membrane. They are the powerhouse of a cell as they play an important role in releasing energy. Ribosome: They are small organelles made up of RNA-rich cytoplasmic granules and they are the sites of protein synthesis. Vacuole:Amembrane-boundorganellespresent inside a cell involved in maintaining shape and storing water, food, wastes, etc. Nucleopore:They are tiny holes present in the nuclear membrane which are involved in the movement of nucleic acids and proteins within the cell. |
