Question

Why do most of the plants grow on land and not in the water? What are the reasons which make land more favourable for the growth of a plant as compared to water?

Answer 1

Mostly multicellular creatures, plants are primarily photosynthetic eukaryotes of the kingdom Plantae. Traditionally, plants were considered one of two kingdoms that included all living organisms that were not animals, and all algae and fungus were considered plants. Nevertheless, all current Plantae related definitions exclude fungus, certain algae, and prokaryotes (the archaea and bacteria).

Complete answer:
Plants require sunshine, water, soil nutrients, and air to thrive. They receive sunshine in abundance when they are planted on the land, but they don't get as much air or nutrients from the water bodies they're simply grown in water.

Plants in water receive less energy because the water absorbs only some of the light. Algae that get into the sunlight when the tide is low will also encounter a dramatic shift in conditions that only a few species can withstand. When plants first began to colonise land, there was a broad range of evolutionary radiation because there was so much difference in conditions, generating distinct habitats for plants to survive in, whereas seas are more homogeneous environments.

Many plants have evolved the capacity to survive both on land and in water. Adaptability is frequently required for a species to obtain a competitive edge over other species by thriving where others cannot. Some plants aerate poor soil, allowing other species to establish themselves.

Note: Green plants get the majority of their energy from sunlight through photosynthesis, which is carried out by primary chloroplasts generated from endosymbiosis relationships with cyanobacteria. The chloroplasts found in the plants are green because they contain chlorophylls a and b. Some plants are parasitic or mycotrophic, meaning they have lost their capacity to generate chlorophyll or photosynthesize yet still retain blooms, fruits, and seeds.
