9Cb1 Leafy matters 1 Name _____________________________ Class ____________ 1 This diagram shows part of a leaf. Fill in the labels on the diagram using words from the box. air space 2 cuticle guard cell palisade cell Fill in the gaps in these sentences using words from the box. You may need each word once, more than once, or not at all. carbon dioxide cells chloroplasts heat holes large light losing night oxygen small stomata waterproof The cuticle is a _______________ layer that stops the leaf _______________too much water. The palisade cells have lots of _______________ to absorb _______________ energy to make photosynthesis happen. Leaves have a _______________ surface area so they can absorb a lot of _______________ energy. Cells in the leaf need to absorb _______________ _______________ from the air. Air gets into the leaf through _______________ in the bottom surface called _______________ . Guard _________________ can close the stomata at _________________ to stop the leaf _________________ water. 3 Some of the glucose made in photosynthesis is used to make new materials for the plant. Match up the materials with their uses. Amino acids Cellulose Fats Oils Starch A store of energy in some seeds and special organs like potatoes. Energy stores found in some nuts. Used to make proteins. Used to make cell walls. Used in cell surface membranes.
