Root hair cells & Tanspiration

Students are instructed to place leafy celery stalks into color water in a beaker overnight. The following day, the students observed the color of the celery leaves changed from green to red. The students cut across the edge of the celery and observed the small tube openings along the edge are also red.

How do the plant systems work together to make the movement of the liquid possible?

• The roots absorb the water, minerals move up the stem, while the stem moves food produced in the leaves down to the roots.

• The roots anchor the plant into the soil and the stem holds the leaves up.

• The roots absorb their own water and minerals and the leaves push out CO2.

• The roots lose water vapor to the soil and the stem loses water vapor through the leaves.

What is the name of the part of the root that allows water and minerals enter?

• root hairs
• epidermis
• phloem
• phyla

How does water move from the soil into the root hair cell and reach the xylem vessels?

• diffusion

• osmosis

• active transport

• none of the above

The loss of water vapour from the leaves of a plant.

• Transpiration

• Evaporation

• Translocation

• Photosynthesis

What helps roots collect water by increasing surface area?

• Osmosis

• Traspiration

• Diffusion

• Root hair cells

The process of water movement in plants

due to evaporation out the stomata

and absorption of water through the root hairs

• Active Transport

• Transpiration

• Stomata

• Guard Cells

Which of the following is a function of roots?

• Carry out photosynthesis

• Absorb oxygen

• Anchor the plant

• Release oxygen

What part of the plant is responsible for: 1) making food 2) exchanging gases and 3) transpiration

• stem

A plant cell wall is mainly composed of

• Protein

• Cellulose

When X decreases, the rate of transpiration increases. What is X?
