Question

Gymnosperms bear separate male and females flowers called as
A. Cones
B. Pines
C. Gametes
D. All of the above

Answer 1

Hint: Gymnosperms is the class of flowerless plants which also means naked seed as their seeds are not present inside the ovary but are present on the surface of a structure called bracts which are leaf-like structures.

Complete Answer:
Let us analyse the options to find the correct answer.
Option A: Cones are formed by leafy green sporophyte and consist of male and female cones. These male and female cones further consist of male and female gametophyte respectively. The female cones are bigger than the male cones. Therefore, this is the correct option.

Option B: Pine is a conifer that belongs to the genus Pinus. There are nearly 120 species that belong to this genus. Therefore, this is the incorrect option.

Option C: Gametes are haploid reproductive cells of organisms that carry a single set of chromosomes. They are also known as sex cells and are formed as a result of meiosis. Therefore, this is the incorrect option.

Thus, the correct option is A) Cones.

Additional information:
- Female cones are located higher in the plants than the male cones.
- The male cone forms the pollen which is a male gametophyte, which fuses with the female gametophyte when carried away by the wind.

Note: In gymnosperms, the female gametophyte is present in the cones rather in the ovary like in the case of angiosperms.
