How does water affect the growth of plants hypothesis?

Answer 1

If the plants get to little water they wilt. Plants wilt when they lose water faster than they gain it from the soil. Before the plant wilts the stomata pores close up. This helps keep water inside but means less carbon dioxide is able to enter the plant. The plant needs carbon dioxide to grow, so growth of the plant slows down because of lack of water.

If the plants get to much water they can not get any air from the soil to be used for respiration and because it is so damp this will encourage disease causing organisms which may affect the plant as well as root rot in the roots. Also the leaves may turn yellow and fall off because of lack of nitrogen in the soil.

Answer 2

If a plant's soil has too much water, the roots can rot. If there isn't enough water in the plant the nutrients it needs cannot travel through the plant. A plant cannot grow if it does not have healthy roots, so the proper balance of water is key when growing plants.

Answer 3

The hypothesis could be that water is essential for plant growth because it is involved in key processes such as photosynthesis, nutrient uptake, and cell elongation. Without an adequate supply of water, plants may experience dehydration, wilting, and ultimately, reduced growth and productivity.

Answer 4

it helps the plant grow like the sun does.90979877
