EVERYDAY SCIENCE

Detailed explanation-1: -The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf. Oxygen, a by-product of photosynthesis, and water vapor exit the leaf. In most land plants, water enters the roots and is transported up to the leaves through specialized cells known as xylem (pronounced zigh-lem).

Detailed explanation-2: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.

Detailed explanation-3: -Water is absorbed by the roots of the plant and travels up the vascular system by the tissue known as xylem. Water enters the leaf and absorbs into the photosynthetic cells by osmosis, combining with CO2 to produce glucose and oxygen. Inside the cell, water can be stored in the vacuole.

Detailed explanation-4: -Each plant contains a branched system of tubes called xylem, which is responsible for water transport from the roots (where it is taken up) to the leaves (where it is used in photosynthesis). Water flows up from the roots, through the trunk and branches, to the leaves, where it is used in photosynthesis.

Detailed explanation-5: -Water Transport from Roots to Shoots The phloem and xylem are the main tissues responsible for this movement. Water potential, evapotranspiration, and stomatal regulation influence how water and nutrients are transported in plants.
