| Question | Answer |
| What are the 4 organs of the plant? | The Roots, the stem, the leaves and the flower |
| What are the main tissue layers of the leaf?(From the top) | From the Top....Wax Cuticle, Upper Epidermis, Palisade Layer, Spongy Mesophyll, Lower Epidermis, Wax cuticle (Includes Stomata) |
| What are the pores on the leaf where the gases diffuse in and out? | Stomata |
| What are the stomata controlled by? | The Guard Cells |
| What is the wax layer for? | To keep water in |
| Why are the upper layers of the leaf so thin? | For maximum absorption of light |
| What are the transport tissues you also find in the leaf that carry water and nutrients from the root? | Xylem and Phloem |
| Where does photosynthesis take place? | In the chlorophyll within the plant cell |
| What is the equation for photosynthesis? | |
| Why does photosythensis not take part in anywhere in the root? | No chlorophyll |
| What layer does photosyntheis take place in? | The palisade layer |
| What specialised cell in the root helps the plant get the water that it requires for photosynthesis? | The root hair cell |
| What is a limiting factor? | A limiting factor is a part of the equation that is in short supply and therefore limits (or slows down) the speeding up of the rate of reaction |
| What are the three limiting factors of photosynthesis? | Light, Temperature and Carbon Dioxide |
| What are Algae? | Single celled plant organisms |
| What is the uses of the glucose made by plants during photosynthesis? | For respiration, storage (as starch), to make cellulose (in cell walls) and to make proteins (such as chlorophyll) |
| What is a greenhouse for? | For artificial control of photosynthesis to make plants grow faster. They can be lit all day, pumped full of COz or have temperature regulators |
