Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How is the water needed for photosynthesis absorbed by the plant?
A
Through the leaves
B
Through the stomata
C
Through the roots
D
Through the stem
Explanation: 

Detailed explanation-1: -Osmosis plays a central role in the movement of water between cells and various compartments within plants. In the absence of transpiration, osmotic forces dominate the movement of water into roots.

Detailed explanation-2: -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.

Detailed explanation-3: -Water from the soil is absorbed by the roots through a process known as osmosis. The cell membrane of the root hair cells acts as a semi-permeable membrane. The cell sap inside the vacuole is a strong solution with low water concentration.

Detailed explanation-4: -In most land plants, water enters the roots and is transported up to the leaves through specialized cells known as xylem (pronounced zigh-lem). Plants have a waxy cuticle on their leaves to prevent desiccation, or drying out.
