Question

Consider the following statements:
a. Female sex organ is a carpogonium
b. Male gamete is called spermatium
c. Male gametes are non flagellated
d. The plants are called as kelps
Identify the correct answer.

• A. a, b, c
• B. a, c, d
• C. b, c, d
• D. a, b, d

Hint:

In red algae (Rhodophyceae), male gametes are non-motile (spermatia) and fertilization occurs without flagellated stages, unlike many other algae groups.

Answer 1

The Correct Option is A

Step 1: Understanding the question context.
The question is based on the reproductive structures and characteristics of certain algae groups, particularly red algae (Rhodophyceae). We need to evaluate each statement carefully based on biological classification and reproductive biology concepts.

Step 2: Analysis of statement (a).
In red algae, the female reproductive organ is called carpogonium. It is a well-established biological fact in phycology. Therefore, statement (a) is correct.

Step 3: Analysis of statement (b).
The male gametes in red algae are called spermatia (singular: spermatium). These are non-motile male gametes, which are characteristic of red algae. Hence, statement (b) is correct.

Step 4: Analysis of statement (c).
Male gametes in red algae are non-flagellated, meaning they do not possess flagella for movement. This is another defining feature of Rhodophyceae. Therefore, statement (c) is also correct.

Step 5: Analysis of statement (d).
Kelps are large brown algae belonging to class Phaeophyceae, not red algae. Therefore, stating that these plants are called kelps in this context is incorrect. Hence, statement (d) is wrong.

Step 6: Final verification and conclusion.
From the above analysis, statements (a), (b), and (c) are correct, while statement (d) is incorrect. Therefore, the correct combination is option (1).
\[ \boxed{(1)\ a,\ b,\ c} \]
