Question

Which phrase is the best definition of sexual reproduction in plants

Answer 1

Reproduction in plants takes place sexually and asexually as well. But the majority of the flowering plants reproduce sexually. The flower is the reproductive part of a plant i.e., both male and female gametes are produced by flowers. Sexual reproduction in plants takes place in flowers. The complete flower typically consists of four parts:

Petals

Sepals

Stamen (male reproductive part)

Pistil/Carpel (female reproductive part)

Stamen (male reproductive part) consists of anther and filament.

The anther is a sac-like structure that produces and stores pollen.

The filament supports the anther.

The pistil (female reproductive part) comprises of three parts- stigma, style, and ovary.

Stigma is the topmost part of a flower.

The style is the long tube which connects stigma to the ovary.

The ovary contains a lot of ovules. It is the part of the plant where the seed formation takes place.

Answer 2

Fertilization.

Step-by-step explanation:

Sexual reproduction involves two parent organisms. The parents here give rise to reproductive cells called gametes by a kind of cell division called meiosis. A gamete here contains a copy of part of the hereditary information organism which produced it.

During plant reproduction which is a diploid phase, also called sporophyte, it produces spores by meiosis that germinate and then divide by mitosis to form a haploid multicellular phase, the gametes here that produces gametes directly by mitosis. This form of life cycle, involving alternation between two multicellular phases.

During sexual reproduction, a gamete from one parent fusses with a gamete from another parent.
