Plant Growth and Development. Growth is defined as an irreversible change in physical form. In plants, a combination of cell growth and cell division results in an almost indefinite growth. This ability is due to the presence of tissues called meristems at certain parts of the plant body. See Also: Important Questions for Class 11 Biology.

Plants that grow in mild weather germinate at low temperatures whereas those that grow in hot regions germinate at high temperatures
Q. No. Identify the incorrect statement about ABA growth regulator. (1) It increases the tolerance of plants against different stresses. (2) It acts as general plant growth inhibitor and inhibitor of metabolism. (3) It helps in seed maturation and dormancy. (4) It promotes morphogenesis and differentiation of shoots Pinus seed cannot germinate and establish without fungal association. This is because: 1. its seeds contain inhibitors that prevent germination. 2. its embryo is immature. 3. it has obligate association with mycorrhizae. 4. it has very hard seed coat.
