what is the main difference between the growth of animals and plants?
Answers
Answer:
Plant Growth:
1. Plants possess well defined growing points or meristems.
2. Growth is apical, intercalary or lateral.
3. Growth is indefinite or unlimited.
4. Plant growth continues throughout the life of a plant.
5. New organs continue to be formed throughout the life of a plant.
6. Old organs are replaced by new organs.
Difference Animal Growth:
1. Growing points or meristems are absent.
2. Growth is diffused.
3. Growth is definite or limited.
4. Growth stops in animals as soon as they mature, long before the appearance of senescence.
5. All organs are formed in the embryo. Later on, no new organs are added.
6. There is no such replacement.
Plants differ from animals in their manner of growth. As young animals mature, all parts of their bodies grow until they reach a genetically determined size for each species. Plant growth, on the other hand, continues throughout the life span of the plant and is restricted to certain meristematic tissue regions only.
