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
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

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
It is a unique process in flowering plants where one sperm cell fertilizes the egg to form the zygote, while another sperm fuses with two polar nuclei to form the triploid endosperm, which provides nourishment to the developing embryo.
