Explanation:

• Question 10: Binary fission is a form of asexual reproduction. In this process, one cell divides into two. Since it is asexual (no genetic recombination from two parents), the daughter cells are identical to each other and to the parent cell (in the absence of mutations).
• Question 11: Yeast is a single - celled fungus. Budding is a common form of asexual reproduction in yeast. In budding, a small outgrowth (bud) forms on the parent cell, which then detaches to become a new individual.
• Question 12: During budding (e.g., in yeast), an outgrowth (bud) forms on the parent cell. This bud grows and then detaches to become a new cell.
• Question 13: Moulds (fungi) reproduce asexually by spore formation. Spores are produced in structures like sporangia and are dispersed. When conditions are favorable, they germinate to form new mould.
• Question 14: Spores are a means of asexual reproduction (and in some cases sexual reproduction in a different context for fungi and plants). They remain dormant in harsh conditions. When conditions are favorable (e.g., proper moisture, temperature, and nutrients), they will grow and divide (germinate).
• Question 15: The cell cycle is involved in all forms of asexual reproduction where new cells are formed from pre - existing cells. Budding involves the parent cell going through the cell cycle to form a bud (new cell). Binary fission is a type of cell division (a simplified form of the cell cycle for prokaryotes or some simple eukaryotes). Spore formation also involves cell division processes (mitosis in many cases) within the sporangium to produce spores.
