Which of the following is not found in algae?

Options

A. Meiosis
B. Embryo
C. Zygote
D. Fertilization

Answer

To determine which of the following is not found in algae, we need to analyze the options provided: meiosis, embryos, zygote, and fertilization.

### Step-by-Step Solution:

1. **Understanding Algal Reproduction**: Algae can reproduce both sexually and asexually. In sexual reproduction, male and female gametes (sperm and egg) fuse in an open water environment.

2. **Identifying the Zygote**: When the sperm and egg fuse, they form a zygote. This zygote is a crucial part of the reproductive cycle in algae.

3. **Meiosis in Algae**: Meiosis occurs in algae, particularly during the formation of gametes. This process is essential for sexual reproduction as it reduces the chromosome number in gametes.

4. **Fertilization in Algae**: Fertilization, which is the fusion of the sperm and egg to form a zygote, also takes place in algae.

5. **Embryonic Development**: In most algae, after fertilization, the zygote develops directly into a new organism without going through an embryonic stage. This is a key distinction because, in many higher plants, the zygote develops into an embryo before becoming a mature plant.

6. **Conclusion**: Since embryos are not formed in algae, the correct answer to the question "Which of the following is not found in algae?" is **embryo**.

### Final Answer:
The option that is not found in algae is **embryo**.
