Question

Gynoecium has many free pistils in
A. Aloe
B. Tomato
C. Papaver
D. Michelia

Answer 1

Hint: The gynoecium is the innermost whorl of a flower or the female part of a flower; it consists of one or more pistils. This is typically surrounded by the pollen-producing reproductive organs, which are the stamens, which is male reproductive parts of plants or flowers.

Complete answer:
Plants reproduce or give rise to new organisms through the process called as sexual reproduction in which both male and female are required and these male and female reproductive organs produce gametes which is male and female gametes respectively.
When these male and female gametes fuse with each other they form zygote which further develops into seed and produces a new individual.
Gynoecium is the female reproductive part of the plant and androecium is male reproductive organ of the plant. Androecium consists of many stamens which is made up of anther and long stalk called filament. Gynoecium produces the female gametes that is, ovule and androecium produce male gametes called pollen grains.
Gynoecium consists of stigma, style and ovary. This part produces ovules and develops into seeds and fruits. Gynoecium is composed of carpels which is leaflike, seed-bearing structure that is innermost whorl of a flower. Fertilization of an egg cell within the carpel by a pollen grain results in seed development within the carpel.
If more than one carpel is present in Gynoecium this condition is known as polycarpellary and if all carpels in the Gynoecium are free then this situation is called as apocarpous. Example of this condition is Michelia.

Thus, correct answer is option ‘D’.

Note: Condition of presence of many free pistils is also known as apocarpous and carpel and pistil are two different names of the same leaflike structure present in the flower. Other examples of apocarpous are lotus, buttercup, magnolia, etc.
