Q. Question 4
State the main difference between asexual and sexual reproduction.

Q.

The picture below shows some yeast cells used in bread making. Why do you think the cells form long chains? Choose the option that explains this phenomenon.

1. The cells reproduce by multiple fission which appears to be chain like.

2. The first cells reproduce by budding and then the daughters by continuous binary fission that creates long chains.

3. The first cells reproduce by binary fission after which the daughters continuously create new buds. This creates a long chain.

4. The parent cell creates daughters by budding which in turn create more by budding. This creates long chains.
