Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The ovule is the female reproductive part of a flower that develops into the seed after fertilization. After pollination, the ovule matures into a seed containing the embryo, while the ovary develops into the fruit. Stems and leaves are vegetative parts not directly involved in seed formation.

Multiple choice

Which of the following types of placentation is found in apple and hibiscus?

  1. Marginal placentation

  2. Free Central placentation

  3. Axile placentation

  4. Free basal placentation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In this type, the ovary has two or more carpels, syncarpous and has two or more locules. The ovules are borne at or near the centre on the axis formed by the union and fusion of the septa (partitions) and usually in vertical rows e.g., apple, hibiscus etc..

Multiple choice

The sperm cells are formed by

  1. Germ Cell

  2. Tube Cell

  3. Tapetum

  4. Sporoderm

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This cell forms the sperm cells that fertilize the egg in the flower. In the loculi of the anthers, cells produce pollen mother cells. They undergo the process of mitosis to form sperm cells: each mother cell creates four sperm cells. The original germ cell divides into two sperm cells. This split can occur before or after the grain reaches the stigma, depending on the species.

  3. The stems of dicots are usually tough.

  4. When a dicot germinates, it produces numerous seed leaves.

  5. Dicots have two seed leaves inside the seed coat.
