Practice Questions
1.State the definition of a tissue
A tissue is a group of cells with a similar structure and function.
2. List the names of three different plant tissues.
Any three of the following:
1. Epidermal tissues
2. Palisade mesophyll
3. Spongy mesophyll
4. Xylem
5. Phloem
6. Meristem tissue
3. Describe 3 ways the leaf is adapted for photosynthesis.
Any three of the following
| Leaf feature | How it is adapted |
|---|---|
| Leaf surface | Large surface area to absorb more sunlight |
| Thin | Short diffusion distance for gases |
| Chloroplasts contain chlorophyll | Chlorophyll will absorb light energy for photosynthesis |
| Veins which contain xylem and phloem | Xylem transports water and mineral ions from roots to the leaves. Phloem transports sucrose and amino acids from the leaf to other parts of the plant such as fruits or roots. |
| Air spaces in leaf | Spongy mesophyll section has air spaces to allow gases to circulate by diffusion |
| Guard cells | Guard cells open and close the stomata |
