24 Plants have three main organs: Roots Stems Leaves Plant Parts!!!Plants have three main organs:RootsStemsLeaves
25 Plant Parts!!! Plant Organ Function Roots Absorbs water and nutrients. Anchors plant to the ground.StemsSupports the plant body.Transports water and nutrients.LeavesCapture sunlight for photosynthesisGas exchange (stomata)
26 Plant Vascular (transport) Systems! A plant’s vascular system (think veins) carries water and sugary sap all the way through the plant from roots to stem to leaves.
27 Plant Vascular (transport) Systems! Two types:1. Xylem – carries water from roots to rest of the plant2. Phloem – carries sugars (called sap) from the leaves to the rest of the plant
34 Stomata are opened and closed by guard cells that surround the stoma. Plant Leaves!Stomata (opening on underside of leaves for gas exchange) are found here.Stomata are opened and closed by guard cells that surround the stoma.Closing stomata prevents water loss and keeps the plant from drying out.
