The seeds of plants contain
a. ovules.
b. embryos.
c. sepals.
d. both
a. and
b.

The correct answer is- b. embryos.

A seed is tiny, tough plant part ( that contains tiny plant called embryo), surrounded by a protective covering and gives a complete plant.

The seed formation in an essential step in the reproduction of seed plants ( such  gymnosperm and angiosperm).

Ovule present within an ovary gives rise to seeds when fertilized by pollen grain. The embryo is developed from the zygote and the seed coat is formed by the integuments in the ovule.

Thus, plant seeds contain embryo is the right answer.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

multiply it by 5 in order for you to understand i cant give an exact answer.
