A diploid parent plant body produces _____ gametes and a haploid parent plant body produces _______ gametes.

Options

A. diploid, haploid
B. haploid, diploid
C. diploid, diploid
D. haploid, haploid

Explanation

### Step-by-Step Solution:

1. **Understanding the Terms:**
- A diploid organism has two complete sets of chromosomes, represented as 2N.
- A haploid organism has one complete set of chromosomes, represented as N.

2. **Gamete Formation in Diploid Organisms:**
- In diploid organisms, gametes are produced through a process called meiosis.
- Meiosis is a reductional division that reduces the chromosome number by half, resulting in haploid gametes.
- Therefore, a diploid parent plant body produces **haploid gametes**.

3. **Gamete Formation in Haploid Organisms:**
- In haploid organisms, gametes are produced through a process called mitosis.
- Mitosis is an equational division that maintains the same chromosome number.
- Thus, a haploid parent plant body also produces **haploid gametes**.

4. **Final Answer:**
- A diploid parent plant body produces **haploid gametes** and a haploid parent plant body produces **haploid gametes**.
