Question

Fusion of male and female gametes is termed as

• A. Reproduction
• B. Vegetative propagation
• C. Cell division
• D. Respiration

Answer 1

The correct option is A

Reproduction

The correct option is A.

Explanation of the correct option :

1. The process through which the parent produces new individuals is called reproduction. This process is important to the survival of life on Earth.
2. There are two methods for organisms to reproduce: sexual reproduction and asexual reproduction.
3. Fertilization is the process of producing a zygote by combining a male and a female gamete (reproductive cells). The zygote divides into a new individual after each cell division.

Explanation of the incorrect options:

Option B:

1. Vegetative propagation is the process of growing new plants from old parts of another plant, such as roots, shoots, and leaves, without using any reproductive organs.
2. For example, Guava trees can be propagated from their roots, whereas Bryophyllum can be propagated from its leaves.

Option C:

1. Cell division occurs when a parent cell divides into two or more daughter cells. Normally, cell division occurs as part of a larger cell cycle.
2. Cell division may be divided into three types: Binary Fission, Mitosis, and Meiosis
3. A cell cycle and cell division take about 24 hours to complete.

Option D:

Respiration is a metabolic process in which an organism's living cells obtain energy (in the form of ATP) by inhaling oxygen and exhaling carbon dioxide produced by the oxidation of complex organic substances.

Final answer: Fusion of male and female gametes is termed reproduction.
