Answer to Problem 4A

Correct answer :

The correct answer is option (B) embryo

Explanation of Solution

Explanation/justification for the correct answer :

Option (B) embryo. If a plant is fertilized, the male and female cells create a zygote − a single cell that will divide into a new entity and develop into one. That zygote will eventually form the plant embryo which is protected by the parent plant by forming a container around it, which is a seed. So, the correct answer is option (B).

Explanation for incorrect answer :

Option (A) Flower. Flower is the reproductive organ of a plant. A flower is a member of a plant responsible for the development of fresh seeds. It also consists of petals, which can have an enticing smell. So, this is an incorrect answer.

Option (C) Cone. Cone, also called strobilus, comprising the reproductive organs of certain non-flowering plants in botany, mass of scales or bracts, typically ovate in form. So, this is an incorrect answer.

Option (D) Fruit. Fruit is the fleshy or dried ovary of a flowering plant, which includes seeds. So, this is an incorrect answer.
