Question

does self pollination produce superior ovaries ? justify your answer​

Answer 1

Explanation:

Ovary position is a useful feature in classification. An ovary attached above other floral parts is termed superior (see photograph); when it lies below the attachment of other floral parts, it is inferior (see photograph).

Answer 2

Answer:

Yes, but it's contain disadvantage

Cleistogamy or automatic self-pollination is the characteristic of certain plants to propagate by using non-opening, self-pollinating flowers e.g., grasses. The main advantage of cleistogamy is that it requires fewer plant resources to produce seeds than chasmogamous plants because development of petals, nectar and large amounts of pollen are not required. Thus, cleistogamy is particularly useful for seed production on unfavourable sites or adverse conditions. For example, Impatiens capensis has been observed to produce only cleistogamous flowers maintain populations on unfavorable sites. The disadvantage of cleistogamy is that self-fertilization occurs, which may suppress the creation of genetically superior plants.
