Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ helps plants to grow and not dry up
A
water
B
oxygen
C
roots
D
floods
Explanation: 

Detailed explanation-1: -Plants have little pores (holes or openings) on the underside of their leaves, called stomata. Plants will absorb water through their roots and release water as vapor into the air through these stomata. To survive in drought conditions, plants need to decrease transpiration to limit their water loss.

Detailed explanation-2: -It is also possible to grow plants hydroponically. Hydroponically grown plants are grown in a solution of water containing the necessary plant nutrients. A variety of methods are used to provide support and oxygen for the roots.

Detailed explanation-3: -Aquatic plants are the plants which are adapted to grow in water. Plants like lotus and hydrilla are examples of aquatic plants.

Detailed explanation-4: -Plants need water for photosynthesis. Absorbed by the roots, water travels through a plant’s stems to the chloroplasts in the leaves. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop.
