5C_Photosynthesis+Review


 * 1) Why are the palisade mesophyll tightly packed and arranged at right angles to the epidermis?
 * 2) Why are the guard cells bean-shaped?
 * 3) Name the 3 types of cells in the leaf that contains chloroplasts and 1 type that doesn’t.
 * 4) Why are stomata found mainly on the lower epidermis of horizontal leaves and not the epidermis?
 * 5) Most terrestrial plants have stomata on the lower epidermis yet many aquatic plants like water lilies have stomata only on the upper epidermis. Explain why this is so.
 * 6) What happens if I coat all the leaves of a plant with oil? Explain.
 * 7) Construct a table each to show the differences between Palisade Mesophyll and Spongy Mesophyl;l and differences between Guard Cells and Epidermal Cells.
 * 8) How is the leaf adapted for Photosynthesis?


 * 1) the maximum amount of light can be intercepted. If there are big gaps between the cells then more of the light hitting the leaf will just pass straight through.
 * d
 * 1) Maristem and Epidermis cells do not contain chloroplast. Cells in the top half of the leaf, called palisade cells, have many chloroplasts. Cells in the bottom half of the leaf, called spongy cells, have fewer chloroplasts. Guard cells have //chloroplasts.//
 * 2) Stomatas are found on the bottom of the plant to prevent excess water loss. By avoiding direct contact with the sun where the plant is most likely to lose water, the plant can preserve water.
