EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -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.

Detailed explanation-3: -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. Roots grow from their tips and initially produce thin and non-woody fine roots.

Detailed explanation-4: -How does it do that? Plant stems have some very special cells called xylem. These cells form long thin tubes that run from the roots up the stems to the leaves. Their job is to carry water upward from the roots to every part of a plant.
