Question

Out of many papaya plants growing in your garden, only a few bear fruits. Give reason.

Answer 1

Hint: Papaya is a prolific crop of tropical fruit that is grown worldwide in tropical and subtropical regions. Papaya has three sex types: male, female, and hermaphrodite. It is either dioecious with males and females in any given papaya breeding scheme, or gynodioecious with hermaphrodites and females.

Complete answer:
Garden might consist of numerous papaya plants and they produce flowers. Out of which, only a few flowers develop into fruits. This is because papaya plants are dioecious, in general. Flowers of the papaya plant are unisexual (i.e.) a plant has either male flowers (with stamens) or female flowers (with pistil). Only the female flowers develop into fruit after pollination, and not the male ones.
Carica papaya is a flowering plant, which means that it reproduces by alternating generations sexually. The life cycle has a stage of diploid sporophyte that is followed by a period of the haploid gametophyte. Through meiosis, the sporophyte generates spores while the gametophyte produces gametes through mitosis. In flowering plants, for example, the C. Papaya is formed in the archegonium by the female gametes (eggs) and in the antheridium by the male gametes (sperm). Ever after C. Papaya is a vascular plant, and the sporophyte is its dominant stage.

Additional Information: Male, female, or both may be a single plant, but typically they are one or the other. Only female flowers yield fruit, not males. This plant is able to produce fruit in as little as 18 months and grows very quickly. With sizes ranging from 1 lb to up to 20lbs, the fruit itself can get very big as well. The optimal mating and growing conditions of Carica papaya are a little picky. Specific temperatures and water are needed, but if you pay attention to these two things, you can grow your own papaya plant at home.

Note: Frankel & Galun (1977) reported that wind and insects were the papaya's main pollinating agents. Since the papaya tree can be female, male, or hermaphrodite, to ensure pollination and fruit production, it seems natural that the pollen can be carried out by wind and/or insects.
