FAQs on Binary Fission in Amoeba & Budding in Yeast Video Lecture - Crash Course: Class 10

1. What is binary fission in Amoeba?
Ans. Binary fission is a form of asexual reproduction in Amoeba where the parent cell divides into two daughter cells of equal size. This process involves the replication of the genetic material followed by the division of the cytoplasm to form two new cells.
2. How does binary fission occur in Amoeba?
Ans. In Amoeba, binary fission occurs when the parent cell elongates and its nuclear material (DNA) replicates. The cell then undergoes constriction in the middle, leading to the formation of a furrow. Eventually, the furrow deepens and separates the parent cell into two daughter cells.
3. What is budding in yeast?
Ans. Budding is a form of asexual reproduction in yeast where a small bud or outgrowth appears on the parent cell. This bud grows in size and eventually detaches from the parent cell to become an independent individual. The newly formed bud is genetically identical to the parent cell.
4. How does budding occur in yeast?
Ans. In yeast, budding occurs when a small bud forms on the parent cell. This bud grows in size by taking in nutrients and replicating its genetic material. Eventually, the bud develops into a mature individual and detaches from the parent cell, forming a new yeast cell.
5. What are the advantages of binary fission and budding as modes of reproduction?
Ans. Both binary fission and budding are efficient modes of asexual reproduction. They allow organisms like Amoeba and yeast to rapidly produce offspring without the need for a mate. This enables them to colonize new environments quickly and adapt to changing conditions. Additionally, since the offspring are genetically identical to the parent, they inherit all the advantageous traits, increasing the chances of survival and adaptation.
