Question

A true fruit develops from:
A. Ovary
B. Thalamus
C. Petals
D. Receptacle

Answer 1

A fruit is the result of fertilization between the ovules and pollen grains. The fruit represents the next generation of the plant as it contains the seeds.

Step by step answer: The ovary is the enlarged basal part of the female reproductive organ of a flower. It contains the female plant gametes known as the ovules. The pollen tube from the stigma carrying the pollen grains/ male gametes reaches the ovules for fertilization. The wall of the ovary forms the wall of the fruit.
After the processes of pollination and fertilization, the carpels develop into the fruit (ovary) and the seeds within it (ovules). The process of fruit development is initiated by several growth-regulating hormones that are produced by the developing seeds
Hence, the correct answer is Option A: Ovary

Additional Information:
-The thalamus is the thickened part of a stem or the pedicel from which the flower organs and whorls grow. In the case of some accessory fruits as in the brinjal and strawberry, this receptacle gives rise to the edible part of the fruit
-The receptacle is the axis/ stem to which the floral organs and whorls are attached. The floral organs are attached in a low continuous spiral. This is commonly seen amongst the primitive angiosperms
-Petals are the modified forms of leaves. They surround the indirect reproductive parts of the flowers. They are often brightly colored or unusually shaped to attract insect pollinators. The petals of a flower as a group are called the corolla
Note: Sometimes fruits are formed from a different part of the plant. These fruits are known as accessory fruits. Aggregate fruits are formed from the several ovaries of a single flower. For example, raspberries and blackberries. Multiple fruits develop from the fusion of the ovaries of several flowers. For example, pineapples and mulberries.
