Question

Why lysosomes and centeosomes are not present in the plant cell?

Answer 1

Plant cells do not contain lysosomes. Lysosomes are present in the cells of animals, and they are responsible for breaking down waste and other cell debris. According to research from Princeton University, in animals, lysosomes assist the body with digesting nutrients from food. In plants as well as in yeast cells, this job is performed by lytic vacuoles. Lytic vacuoles detoxify plants and maintain overall homeostasis within the cell. Without these parts, a plant would not grow to full maturity. Similarly, without lysosomes, animals would be unable to process food within the body or break down the body's cells after death.They don't need them as the cell wall keeps out large molecules that lysosomes break down.
Spindle formation in plants is very different from most other eukaryotes owing to the fact that plant cells lack centrosomes or spindle pole bodies, which act as the microtubule organizing centers in animal cells. The evolutionary advantage that animal cells gain due to the presence of centrosomes is the ability to direct drastic changes in their shapes during mitosis. On the other hand, plant cells have a rigid cell wall that does not undergo any major changes in shape during mitosis; and the cell wall itself can organize many of the microtubules that form the spindle during mitosis.
