Question: How many chromosomes are present in the gametes of a plant with a total of 30 chromosomes in its somatic cells?

Options:

Correct Answer: 15

Solution:

Gametes are haploid, so they will have half the number of chromosomes, which is 15.

How many chromosomes are present in the gametes of a plant with a total of 30 chromosomes in its somatic cells?

How many chromosomes are present in the gametes of a plant with a total of 30 chromosomes in its somatic cells?

Step 1: Understand that somatic cells are the regular body cells of an organism.
Step 2: Know that somatic cells contain a diploid number of chromosomes, which means they have pairs of chromosomes.
Step 3: Identify that the total number of chromosomes in the somatic cells of the plant is 30.
Step 4: Calculate the number of chromosomes in the gametes by dividing the total number of chromosomes by 2, since gametes are haploid.
Step 5: Perform the calculation: 30 chromosomes ÷ 2 = 15 chromosomes.
Step 6: Conclude that the gametes of the plant will have 15 chromosomes.

Chromosome Number in Somatic vs. Gametes – Somatic cells are diploid (2n), while gametes are haploid (n), meaning gametes contain half the number of chromosomes found in somatic cells.
