Question
(a) Among the asexually and sexually reproducing organisms, where is meiosis essential? (b) What are non-motile spores?
Answer
(a) Meiosis is essential in sexually reproducing organisms, as it is the process by which gametes are formed, which contain half the number of chromosomes as the parent cell. Meiosis is not essential in asexually reproducing organisms, as they produce offspring that are genetically identical to the parent cell and do not require the fusion of gametes.
(b) Non-motile spores are a type of spore that cannot move by themselves and rely on external factors such as wind, water, or animals to disperse them to new locations. These spores are produced by many different types of organisms, including plants, fungi, and some bacteria.
