BOTANY

Detailed explanation-1: -After fertilization, the ovule develops into a seed, and the ovary develops into a fruit.

Detailed explanation-2: -The pollen grains are released from the anther to land on a stigma during pollination. The pollen grain germinates, forming a pollen tube that delivers the sperm to the egg in the ovule during fertilization. The sporophyte embryo develops in the seed. Upon germination of the seed, the sporophyte resumes growth.

Detailed explanation-3: -Seeds contain a plant with leaves, stem and roots. The first step a seed takes on its path is germination. Germination is when the plant within the seed begins to grow with the help of water, soil and sun. As the process continues, the plant develops stems and roots.

Detailed explanation-4: -Unlike gymnosperms such as conifers and cycads, angiosperm’s seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower. The flowers of angiosperms have male or female reproductive organs.

Detailed explanation-5: -In a diplontic life cycle, the dominant free-living phase is the sporophyte, diploid (2n). The sporophyte is photosynthetic. The gametophytic phase is represented by single to few-celled haploid gametophytes. All seed-bearing plants, i.e., gymnosperms and angiosperms, exhibit this type of life cycle.
