|
|
It keeps the pollen dry by exposing it to air while keeping the ovary moist
|
|
|
a. It makes it possible for seeds to develop both in the ovary and in the pollen grains.
|
|
|
It encourages animals to carry pollen for cross-fertilization while leaving the ovary alone
|
|
|
a. It allows the plant to self-fertilize more easily since the pollen can drop into the ovary.

Detailed explanation-1: -In some flowers, the ovary is hidden deep within the base of the flower while the pollen is held up in the air, often near a source of nectar. How is this general design helpful to the plant? It encourages animals to carry pollen for cross-fertilization while leaving the ovary alone.
Detailed explanation-2: -Stomata, as mentioned above, are the structures through which gas exchange occurs in leaves. Each stoma is surrounded by two guard cells, which can open and close depending on environmental conditions.
Detailed explanation-3: -The correct answer is Stomata. It is a process in which excess water is lost in the form of vapors from the aerial parts of the plant. Mainly through the stomates of leaves.
Detailed explanation-4: -All leaves change sunlight into energy through photosynthesis. The leaves are the primary food-making part of the plant. Leaves absorb carbon dioxide from the air, combine it with water that comes through the roots of the plants to make food (a sugar molecule known as glucose), and release oxygen into the air.
