Answers
Explanation:
1. The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins.
2.SER mainly carry out the synthesis of lipids.
3. Golgi apparatus is called the traffic police of cell.
4.Cell membrane.
5. If the medium surrounding the cell has a higher water concentration than the cell, i.e., if solution is a very dilute solution, the cell will gain water by osmosis called endosmosis and cell becomes turgid.
6. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. The main components of the cytoplasm are cytosol (a gel-like substance), the organelles (the cell's internal sub-structures), and various cytoplasmic inclusions. The cytoplasm is about 80% water and usually colorless.
7. The ribosome seems to be the smallest organelle.
8.Plasmolysis occurs due to osmosis.
9.The mitochondrial inner membrane consists of a number of infoldings called cristae.
10.the protoplasm is the physical basis of life.
13. The longest animal cell is Nerve Cell.
