Question

Essay on Diversity in plant .

Answer 1

Explanation:

Plants have developed adaptations for different soil types, methods of pollination, daylight hours, temperature, altitude, competition with other plants. The list is endless, even two plants of the same species, separated by geography will have a different genetic make-up.

Plants are multi-cellular and mostly photosynthetic organisms which found essentially everywhere, both in water and on land. The aquatic plants include red, brown and green algae and the land plants include mosses, ferns, gymnosperms and angiosperms.

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

Answer 2

Answer:

Plants are the silent workers of our planet, they want to live and also help others (animals including human beings) to live. They have well-developed metabolic system, which includes both anabolism (synthesis) and catabolism (break­down). On the other hand, animals have only catabolic system.

Anabolic system, like photo­synthesis, is present in most of the plants and catabolic system, like respiration, is present in all plants. Photosynthesis is dependent on light, but the respiration occurs both day and night (throughout their life period). Photosynthesis requires CO2, water, chlorophyll and light. Plants can absorb CO2 from the atmosphere and also utilize the CO2 produced from its own respira­tion.
