Spermatogenesis occurs in the ovaries

In oogenesis, the other that is very small is called a polar body. 

In sexual reproduction, each parent supplies half of the genetic information needed to form a complete individual.

During fertilization, 1 gamete from each parent combines to form a zygote.

Recombination in crossing over occurs during prophase II.

The parent plants have male and female sex cells, called gametes.

Seeds produced through fertilization contain genetic material from both parents which result in an offspring that are not genetically identical to either of the parent plants.

Flowering plants reproduce sexually through a process called pollination.

Flowers contain male sex organs called stamens and female sex organs called pistils.

Pollen must be moved to a part of the pistil called the style for reproduction to take place.

The innermost part of the flower is the sepals which contains the ovary.

The male gametophyte develops and reaches maturity in an immature anther.

In a plant’s male reproductive organs, development of pollen takes place in a structure known as the microsporangium.

The result of microsporogenesis, is either a male gametophyte that is a two-celled pollen grain (with vegetative and generative cells), where the generative cell will later undergo another mitotic division to produce two sperm cells, having a three-celled pollen grain with a vegetative (or tube) cell plus two sperm cells.

The process wherein male gametophyte develops is called megasporogenesis or female gametogenesis.
