Question

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

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

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

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

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

• A. The first cells reproduce by budding and then the daughters by continuous binary fission that creates long chains.
• B. The first cells reproduce by binary fission after which the daughters continuously create new buds. This creates a long chain.
• C. The parent cell creates daughters by budding which in turn create more by budding. This creates long chains.
• D. The cells reproduce by multiple fission which appears to be chain like.

Answer 1

The correct option is C

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

Yeast reproduces by budding. The parent cell first produces a bud. After sufficient time, the bud does not fully detach but instead produces more daughter cells by producing new buds. This continuous process creates long chains of yeast cells which helps the yeast to reproduce quickly.
