transpiration
desert
parenchyma
concentration outside roots causes plant to lose h20
24. Explain why a cucumber or tomato really should be referred to as a fruit?
it has the seeds and all 4 parts of a flower would classify it as a fruit instead of a vegetable
Irish potato
visible light is good because it's not as intense so that it will burn the plant - but it is still intense enough to produce plenty of energy
