Ovary develops into a fruit, not a seed.

Anther produces pollen grains for fertilization, but does not form a seed.

Explanation

Ripened ovary or fertilized ovary is called a fruit.

Post-fertilization changes in plants involve:

endosperm formation

embryo development

seed

fruit formation.

while

Ovules at maturity or ripened ovules are known as seeds.

The second male gamete fuses with the diploid secondary nucleus to form triploid endosperm which nourishes the developing embryo.

Explanation

Explanation

Germination is the process where a seed begins to grow and develop into a new plant.

It starts when the seed absorbs water, swells, and the embryo begins to sprout.

Explanation

• Where the cotyledon emerges from the seed coat and grows above the soil surface.
• Examples of dicot seeds include beans, peas, and tomatoes.
