In This Lesson:
we will study the different plant parts that take up and transport water, nutrients and air to make the plant food:
1. Roots:
• Plant roots have hairlike features (structures) called root hairs that increase the amount of absorbed water and nutrients that the plant needs from the soil.
► Functions of the plant roots:
▌Roots fix (anchor) the plant in the soil .
▌Roots absorb (draw) water and nutrients from the soil, which are needed to make food of plants.

2. Stem:

• Water and nutrients move up the plant's stem through tubes or vessels called xylem.
• Smaller vessels of xylem connect the stem to the leaves.
► Functions of the plant stem:
▌ Stem transports water and nutrients to the rest of the plant through xylem.
▌ Stem supports leaves and flowers of the plant.

► There are many forms of stems:
- Some plants have a wood stem, such as tree trunks and shrubs.

- Most flowers have upright stems.

- Some plants have a climb stem, such as vines (grapes).

- Some stems extend underground, and they are called tubers, such as potato plant.


- Some stems extend above and along the ground and they are called runners.
