To absorb water and minerals from the soil

To protect the plant from pests

To anchor the plant firmly in the soil

By active transport

By diffusion

By osmosis

By phagocytosis

It helps in the production of food

It increases the speed of water and mineral absorption

It prevents the loss of water through transpiration

It assists in the synthesis of plant hormones

Xylem

Phloem

Root cortex cells

Leaf mesophyll cells

Water is not absorbed by the plant

Water is absorbed and transported through the xylem

Water is absorbed by the root hairs only

Water is moving through the phloem

It is stored in the roots

It moves up to the leaves

It is used for photosynthesis

It evaporates from the roots

The stem

The root hair cells

The leaf veins

The flower petals

By observing the color change in the roots

By staining and examining the leaves and stem

By measuring the plant's height growth

By counting the number of root hairs

Water is evenly distributed throughout the stalk

Only specific regions of the stalk are stained

Water transport occurs only in the leaves

The celery is not involved in water transport

Active transport

High concentration of solutes

Lower water potential in the soil

Higher water potential in the soil
