Q. Consider the following differences between plant cell and animal cell: - While plastids are usually present in plant cells, they are absent in animal cells
- While lysosomes are rare in plant cells, they are found in almost all animal cells
Which of the above statements is/are correct?
Answer:
Both 1 & 2
Notes: A lysosome is a membrane-bound organelle found in nearly all animal cells. They are spherical vesicles which contain hydrolytic enzymes that can break down virtually all kinds of bio molecules. Besides degradation of polymers, the lysosome is involved in various cell processes, including secretion, plasma membrane repair, cell signalling, and energy metabolism. Plastids are thought to have originated from end symbiotic cyan bacteria. They are responsible for colour.
