The ovary is half inferior in :a)Sunflowerb)Plumc)Brinjald)MustardCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Position of floral parts on thalamus -

Hypogyny - ovary is at the top and separable from thalamus. ovary is superior and convex

eg: Brassica & malva

perigyny: ovary is half superior and half inferior. example, rose.

Epigyny - calyx & corolla arise from the upperside of ovary & Ovary is completely surrounded by or fused by thalamus. Ovary is inferior. eg: luffa , Aster

Answer

Answer

Plum/peach belongs to the family Rosaceae and it shows half-inferior ovary. So the flowers are perigynous. Sunflower have inferior ovary Plum/peach flowers have a half-inferior ovary. Brinjal (Solanaceae) has a superior ovary. Mustard have superior ovary

Answer

The ovary is half inferior in Plum.

Explanation:

The position of the ovary in a flower can be classified into three types: superior, inferior, and half-inferior. In a superior ovary, the ovary is located above the attachment point of other floral parts, while in an inferior ovary, the ovary is located below the attachment point. In a half-inferior ovary, the ovary is partially below and partially above the attachment point.

In the case of Plum, the ovary is half inferior. This means that the ovary is positioned partially below and partially above the attachment point of other floral parts.

Reason:

The position of the ovary is determined by the relative positions of the other floral parts, such as the sepals, petals, and stamens. In Plum flowers, the sepals, petals, and stamens are attached at the base of the ovary, causing the ovary to be half inferior.

Comparison with other options:

a) Sunflower: In Sunflower flowers, the ovary is superior. The sepals, petals, and stamens are attached below the ovary, causing it to be positioned above the attachment point.

c) Brinjal: In Brinjal flowers, the ovary is superior. The sepals, petals, and stamens are attached below the ovary, causing it to be positioned above the attachment point.

d) Mustard: In Mustard flowers, the ovary is superior. The sepals, petals, and stamens are attached below the ovary, causing it to be positioned above the attachment point.

Therefore, the correct answer is option B, Plum, where the ovary is half inferior.
