The document defines key plant vocabulary terms: Chlorophyll is the green pigment in plants that absorbs sunlight for photosynthesis. Chloroplasts are structures in plant cells that contain chlorophyll and trap sunlight to produce sugar. Xylem transports water up a plant and phloem transports sugar throughout a plant. Photosynthesis produces sugar and oxygen from carbon dioxide, water, and sunlight. Cellular respiration uses sugar and oxygen to produce energy in plant cells. Roots absorb water and transpiration causes plants to lose water through their leaves and stomata.
