Explanation: 

Detailed explanation-1: -Essentially all of the water used by land plants is absorbed from the soil by roots. A root system consists of a complex network of individual roots that vary in age along their length.

Detailed explanation-2: -A. While plants can absorb water through their leaves, it is not a very efficient way for plants to take up water. If water condenses on the leaf during high humidity, such as fog, then plants can take in some of that surface water. The bulk of water uptake by most plants is via the roots.

Detailed explanation-3: -Plants drink water through a process called osmosis. Osmosis is the movement of a liquid into a living thing, creating a balance of that liquid. For example, if a plant needs water it will use osmosis to pull water through the roots until it has enough water to photosynthesize, or make food.

Detailed explanation-4: -Water moves into the roots from the soil by osmosis, due to the low solute potential in the roots (lower s in roots than in soil). This intake o f water in the roots increases p in the root xylem, driving water up.

Detailed explanation-5: -The two primary reasons plants need is air to photosynthesize (make food) and to breathe. Plants need to breathe for the same reason people and animals must breathe – they need oxygen to convert food into energy. The relationship between air and indoor plants is crucial to keeping your plants looking their best.
