Explanation:

1. Cytoplasm is the part of the cell that is surrounded by the cell membrane and contains organelles, water, salts, and other substances.

2. The cell wall is the outermost layer of the cell and surrounds the cell membrane in the case of plant cells only. While, the outermost layer of the animal cells is a cell membrane and isn't surround by any other membrane.

3. A group of similar cells forms a tissue.

4. Tissues are combined to form organs that are involved in various functions.

5. The shape and size of the cells vary with their functions and compositions.

6. Chloroplasts are green colored because they contain chlorophyll.

7. Plastids occur in plant cells only, not in animal cells and are responsible for the manufacturing and storing of food.

8.  Chromosomes contain genes which are responsible for hereditary characteristics.

9. The nucleus is the control unit of the cell because it regulates gene expression and DNA replication during the cell cycle.

10. The shape and size of the cells vary with their functions and compositions.

11. Tissues are combined to form organs that are involved in various functions.

12. Cytoplasm and nucleoplasm are combined to form protoplasm.

13. The smallest unit of life is a cell.

14. Unicellular in which "uni" means one and "cellular" means cells so, unicellular organisms contain one cell only. Ex: Amoeba

15. The cell wall around the cell membrane is non-living in nature.
