What is the function of the xylem?

The xylem is a transport tissue that carries water and minerals from the roots up to the leaves.

How are palisade cells adapted for photosynthesis?

Palisade cells are found near the top of the leaf and are packed with many chloroplasts to absorb as much light as possible.

What is the purpose of stomata?

Stomata are tiny pores on the underside of leaves that allow gases like carbon dioxide and oxygen to enter and exit.

What is the role of root hair cells?

Root hair cells have a large surface area to maximize the absorption of water and minerals from the soil.

What is the difference between xylem and phloem?

Xylem transports water and minerals upwards, while phloem transports sugars produced during photosynthesis to the rest of the plant.

Plant Structure and Function

Remember:

A plant has 5 different parts to it. They are:

Structure of Leaf

🔬 Knowledge Check: Plant Structure and Function

Test your understanding of plant organs, tissues, and specialized cells.

1. Which plant tissue is responsible for transporting sugars from the leaves to other parts of the plant?

Xylem
Phloem
Stomata

2. Why are palisade mesophyll cells located near the top surface of a leaf?

To allow gases to exit the leaf easily
To absorb maximum sunlight for photosynthesis
To prevent water loss from the roots

3. What is the primary function of the root hair cell's long, thin projection?

To increase surface area for water absorption
To anchor the plant firmly in high winds
To perform photosynthesis underground

4. Which specialized cells control the opening and closing of the stomata?

Guard cells
Epidermal cells
Spongy cells

5. What is the main role of the waxy cuticle on the surface of a leaf?

To transport minerals to the stem
To reduce water loss by evaporation
To attract insects for pollination

1. Phloem (Transports dissolved sugars from leaves to the rest of the plant).
2. To absorb maximum sunlight (They contain many chloroplasts for photosynthesis).
3. To increase surface area (Allowing more water and minerals to be taken in from the soil).
4. Guard cells (They change shape to open or close the pores for gas exchange).
5. To reduce water loss (Providing a waterproof barrier for the leaf).
