Correct Answer

(C) Early anaphase

Explanation

Solution: In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell.

[#707] Almost all kinds of vegetative reproduction are carried out by the division known as
Correct Answer

(A) Mitosis

Explanation

Solution: Almost all kinds of vegetative reproduction are carried out by the division known as mitosis.

[#708] Gametes are produced by the process of
Correct Answer

(B) Meiosis

Explanation

Solution: Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

[#709] In each pollen sacs a large number of pollens or microspores are produced by
Correct Answer

(B) Meiosis

Explanation

Solution: In a process called microsporogenesis, four haploid microspores are produced from each diploid sporogenous cell (microsporocyte, pollen mother cell or meiocyte), after meiotic division. After the formation of the four microspores, which are contained by callose walls, the development of the pollen grain walls begins.

[#710] Synapsis occurs during
Correct Answer

(B) Meiosis

Explanation

Solution: Synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosis.
