Plants: Structures for Survival LEAVES Leaves catch sunlight and perform the following functions: Photosynthesis – plant makes own food. Respiration - Energy from the food (sugar) produced by plants is broken down by the plant’s cells. Energy is released. Transpiration - plants release water through the leaves into the atmosphere. What are Leaves functions? (FOOD FACTORY)

Plants: Structures for Survival STEMS Stems support the plant and hold the leaves up to the light. Stems also function as food storage sites. –Xylem - transports water from the roots to the leaves and other plant parts. –Phloem - transport food made in the leaves to growing parts of the plant. What are Stems functions?

Plants: Structures for Survival ROOTS - anchor the plant in the ground. –Absorb water/nutrients from soil. Some store food for the plants (ex. carrots). –Root hairs increase the surface area so more water and nutrients can be absorbed. Two types of roots: fibrous roots and taproots. –Fibrous roots - several main roots that branch off to form a mass of roots (ex. grass, corn, and some trees). –Taproots - one large, main root with smaller roots branching off. (ex. carrots, dandelions, or cacti). What are Roots functions?
