Farmers and gardeners often add fertilizers to the soil while their crops are growing. The fertilizers contain mineral salts. Two of the most important ones are nitrate and magnesium. Nitrate is needed for the plants to make protein, which then is needed to make new cells for growth. Plants also need nitrate and magnesium to make chlorophyll. A shortage of nitrate or magnesium makes plant leaves go yellow. Plants need water for support, cooling, transport, and photosynthesis. Most of the water taken up by the roots eventually diffuses out of the plant’s leaves, as water vapor.

Reorder the following characteristics of what plants need to survive on land:

• Obtain water & nutrients

• Transport materials throughout the plant

• Diffuses water out of the plant’s leaves

Cellular Respiration

When you need a quick boost of energy, you might reach for an apple or a candy bar. But cells do not "eat" apples or candy bars; these foods need to be broken down so that cells can use them.
