Name the conditions necessary for seed germination.

The conditions necessary for seed germination are: Water: It activates enzymes that begin the metabolic processes needed for growth and softens the seed coat to allow the embryo to sprout. Temperature: A suitable temperature range is required for enzymes to function and for the seed to grow. The optimal temperature varies by species. Oxygen: Seeds … Read more

State the contribution of Theophrastus in the discovery of sex in plants.

Theophrastus, a Greek philosopher and botanist (371–287 BCE), made significant contributions to the study of plants, including early observations on plant reproduction. His key contribution to the discovery of sex in plants was his recognition of the male and female aspects of plants. In his work “Enquiry into Plants”, Theophrastus described how some plants have … Read more

Write the differences between:

a) Epigeal and hypogeal germination Epigeal germination: Cotyledons rise above the soil (e.g., bean). Hypogeal germination: Cotyledons remain underground (e.g., pea). b) Asexual and sexual reproduction Asexual reproduction: Involves one parent, no gamete formation, produces genetically identical offspring. Sexual reproduction: Involves two parents, gamete formation, produces genetically diverse offspring. c) Self-pollination and cross-pollination Self-pollination: Pollen … Read more

Give the functional detail of pituitary gland, pancreas and thyroid gland, also mention their disorders.

Functional details of the pituitary gland, pancreas, and thyroid gland, along with their associated disorders: 1. Pituitary Gland The pituitary gland is a small, pea-sized organ located at the base of the brain, often referred to as the “master gland” because it regulates other endocrine glands.
