Answers
Answer;
1)In phagocytosis, or "cell eating," the cell engulfs debris, bacteria, or other sizable objects. ... In pinocytosis, or "cell drinking," the cell engulfs extracellular fluid, including molecules such as sugars and proteins. These materials enter the cell inside a vesicle, although they do not mix with cytoplasm.
2)Lysosomes are known as suicide bags of the cell because they contain lytic enzymes capable of digesting cells and unwanted materials. When lysosomes burst, the lytic enzymes within the organelle spill all over the cell, rupturing the cell membrane or cell wall and inducing the death of the cell.
3)Cell is the functional unit of life because all the functions of body (physiological, biochemical. genetic and other functions) are carried out by cells.
