AP BIOLOGY

Detailed explanation-1: -The water is absorbed by the root hair and undergoes cell to cell movement by osmosis until it reaches the xylem. This water is then transported through the xylem vessels to the leaves and is evaporated by the process of transpiration. The xylem is also composed of elongated cells like the phloem.

Detailed explanation-2: -Hence, water moves from the soil to the root hair cells by the process of osmosis. Osmosis is the movement of water molecules from a region of low concentration to high concentration through a semipermeable membrane.

Detailed explanation-3: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.

Detailed explanation-4: -Upon absorption by the root, water first crosses the epidermis and then makes its way toward the center of the root crossing the cortex and endodermis before arriving at the xylem (Figure 4).

Detailed explanation-5: -Water Transport from Roots to Shoots The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement.
