(a) Plasma membrane (b) Ribosome
(c) Lysosome
(e) Golgi apparatus
(f) Cytoplasm
(g) Asters of centrosome (h) Chromosom,
(i) Glycogen granule (j) Vacuoles​

Answer 1

Answer:

the major functions of the followido

(a) Plasma membrane

Answer 2

Answer:

1. The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
2. Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes.
3. Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
4. A major function of golgi apparatus is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes.
5. Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity. Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place.
6. The main function of asters is to hold the two centrioles at the two opposite poles and help the spindle apparatus to organized and positioned during nuclear division.
7. The most important function of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms.
8. Glycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact than the energy reserves of triglycerides (lipids).
9. The vacuole in cells have three main functions which are to provide the plant with support or rigidity, a storage area for nutrients and waste matter and can decompose complex molecules
