NEET BIOLOGY

Detailed explanation-1: -The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.

Detailed explanation-2: -The plant vascular system is a complicated network of conducting tissues that interconnects all organs and transports water, minerals, nutrients, organic compounds, and various signaling molecules throughout the plant body.

Detailed explanation-3: -The vascular tissues of plants, which are composed of specialized conducting tissues, xylem and phloem, form continuous systems through the plant body and provide transport pathways for water, nutrients, and signaling molecules and support a plant body against mechanical stresses.

Detailed explanation-4: -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.

Detailed explanation-5: -The bulk of water absorbed and transported through plants is moved by negative pressure generated by the evaporation of water from the leaves (i.e., transpiration)-this process is commonly referred to as the Cohesion-Tension (C-T) mechanism.
