Answer:
Yeast cell is different from an onion skin cell in that Yeast can reproduce by budding while onion skin cells do not reproduce by budding.
Explanation:
- Reproduction is one of the characteristics of living organisms. All living organisms undertake reproduction to give rise to new organisms.
- There are two major types of reproduction namely asexual and sexual reproduction.
- Asexual reproduction is a form of reproduction that does not involve the fusion of gametes among organisms. Examples of asexual reproduction are budding in yeast and vegetative propagation in plants such as onions.
- Sexual reproduction, on the other hand, involves the fusion of gametes from male and female organisms which results in the formation of an embryo that develops to the fetus which becomes the offspring.
- Therefore, we could say that yeast cells reproduce asexually through budding while onions reproduce asexually through vegetative propagation.
