The correct Answer is:
To solve the question regarding the male and female gametes in Fucus, we can break down the information step by step: ### Step 1: Understanding Fucus Fucus is a genus of brown algae, commonly found in marine environments. It reproduces sexually, producing male and female gametes. ### Step 2: Identifying Male Gametes In Fucus, the male gametes are produced in structures called antheridia. These male gametes are known as antherozoids (or sperm) and are motile. This means they can swim through water to reach the female gametes. ### Step 3: Identifying Female Gametes The female gametes in Fucus are produced in structures called oogonia. These female gametes are non-motile eggs. They do not have the ability to move on their own and rely on the motile male gametes for fertilization. ### Step 4: Conclusion Based on the information gathered, we can conclude that in Fucus: - Male gametes (antherozoids) are motile. - Female gametes (eggs) are non-motile. ### Final Answer Thus, the correct answer to the question is **C: motile and non-motile respectively**. ---
