HORTICULTURE

Detailed explanation-1: -Female cones (ovulate cones) contain two ovules per scale. One megaspore mother cell (megasporocyte) undergoes meiosis in each ovule. Three of the four cells break down leaving only a single surviving cell which will develop into a female multicellular gametophyte .

Detailed explanation-2: -These grains have winglike structures that allow the wind to carry them up the tree to the female cones. Deep inside the female cone, ovules develop into the mature female gametophyte that bears fertile egg cells.

Detailed explanation-3: -The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous and much less conspicuous even at full maturity.
