Question

Plants are able to produce fruits with the help of insects as they are
A. Help in aestivation
B. Help in pollination
C. Help to overcome dormancy
D. None of the above

Answer 1

Seeds are produced in many similar plant species, and angiosperms are differentiated from gymnosperms by their method of development. In a hard or fleshy form called a fruit that surrounds the seeds for protection, angiosperm seeds are produced to ensure safe growth.

Complete Answer:
An immature plant covered in a protective outer coating is a seed. Crop formation is part of the reproductive mechanism of seed plants, like gymnosperm plants and angiosperm plants, which are spermatophytes. After fertilisation by pollen and some development inside the mother plant, seeds are the result of the matured ovulum. The embryo is produced from the ovulum integuments of the zygote as well as the seed coat.

Now, let us find the solution from the options-
- Aestivation, while occurring in summer instead of winter, is a condition of animal dormancy, equivalent to hibernation. Aestivation is characterised by inactivity and a decreased metabolic rate that is added in response to rising temperatures and arid environments. Thus, option A is not the correct option.
- Nectar, a sugary fluid that several insects consume, is provided by many flowers. Pollen grains adhere to the body as an insect settles on a flower to feed. These pollen grains are moved to the flower’s stigma while the insect travels to some other flower of the same species, and pollination happens. The plants make fruits after pollination.
- Dormancy when in tubers or seeds there is a failure of germination even if the necessary requirements are given. Dormancy is dependent on the impermeability of hard seed coats or the lack of enzyme supply and operation (internal dormancy) required for germination. Thus, option C is not the correct option.

Thus, the correct option is option (B) Help in pollination.

Note: It is termed dehiscent, and is also characteristic for similar classes of plants, as the fruits open and disperses their seeds on a daily basis; these fruits contain capsules, legumes, follicles and silica. When fruits may not open and consistently expel their seeds, they are referred to as indehiscent, like fruit achenes, nuts, and utricles.
