Explanation:

a) Pollination :- Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.

b) Flower :- A flower is the part of a plant which is often bright.

c) Parasitic Roots :- A parasitic plant is a plant that derives some or all of its nutritional requirement from another living plant. ... All parasitic plants have modified roots, called haustoria, which penetrate the host plant.

d) Modified Leaves :- A modified leaf is an adaptation of plant meant for its own survival due to its environmental stress. When a leaf performs functions other than photosynthesis and transpiration, structural changes may occur. ... The plant's leaves are covered in thorns to protect itself from potential predators and to preserve water.

e)Heterotrophs :-

A heterotroph is an organism that cannot produce its own food, instead taking nutrition from ... dioxide or organic carbon as the carbon source, meaning that mixotrophs have the ability to use both heterotrophic and autotrophic methods.
