In Spirogyra, reproduction involves the fusion of two (i)______ gametes. This type of reproduction is known as (ii)________

Options

A. i-dissimilar, ii-anisogamous
B. i-similar, ii-isogamous
C. i-dissimilar, ii-isogamous
D. i-similar, ii-anisogamous

Answer

To solve the question regarding the reproduction in Spirogyra, we can break it down into two parts:

1. Identify the type of gametes involved in Spirogyra reproduction.
2. Determine the name of the reproduction process based on the type of gametes.

### Step-by-Step Solution:

**Step 1: Identify the type of gametes in Spirogyra.**
- In Spirogyra, the gametes that fuse during reproduction are similar in morphology. These gametes are known as isogametes. Isogametes are identical in size and shape, meaning they cannot be distinguished from one another by their appearance.

**Step 2: Determine the name of the reproduction process.**
- The process of reproduction that involves the fusion of two similar gametes (isogametes) is called isogamous reproduction. This type of reproduction is characterized by the equal size and motility of the gametes involved.

### Final Answer:
(i) isogametes
(ii) isogamous reproduction
