OBSERVING+STOMATA+FROM+A+LEAF

1.- Write down the general formula for ** photosynthesis **.


 * WATER +CARBON DIOXIDE+MINERAL SALTS --- **** > **** GLUCOSE+ OXYGEN **

2.- What condition does the closing of the stomata help to prevent?


 * The closing of the stomata prevents dehydration **

**__ Conclusion: “the hotter a plant the more water it will lose” __**

1.- What substances **enters** the leaf through the stomata?


 * Oxygen enters for respiration and Carbon dioxide enters for photosynthesis. **

2.- What substances **exit** the leaf through the stomata? Gases exit the leaf( Oxygen from photosynthesis and Carbon dioxide from respiration) and water vapour.

3.- Why do stomata have the **ability to close**?
 * Because when a plant encounters adverse conditions (such as drought), stomata shut and prevent the loss of water. **

4.- On what **side** of the leaf are stomata more located?
 * Stomata are more located on the underside of the leaf. **

5.- Why are there more stomata on the side answered for 4 than the other side of the leaf? **On the underside there is less sunlight exposure from the sun. If the stomata were on top of the leaf, the cells would DRY UP too easily from the heat.**
