Vascular Plants Vascular plants have tubes. These tubes can be found in roots, stems, and leaves. The tubes form a network to carry water and nutrients throughout the plant.
Function of Roots Plant roots form an anchor for the plant – preventing them from falling over in high winds. Most roots spread as far as the plant is tall. Roots take in water and nutrients through the soil using root hairs.
Function of Roots Different types of roots are adapted to different environments. –Desert plants have roots which spread far from the plant but stay near the surface. –These roots are able to take in large amounts of water.
Function of Roots Forest trees have deep roots because there is more water in the soil.
Function of Roots In a tropical rainforest, some roots attach themselves to trees and take in water directly from the moist air.
Common Parts Types of Roots –Fibrous roots - resemble tree branches –Taproot – a single, thick root, usually deep within the ground
Common Parts Types of Roots –Prop roots – begin above the ground, help plants grow in wet, loose soil
Storage Roots Storage roots, sometimes called tubers, store extra food and water to help them survive changes in their environments. –Examples: beets, carrots, sweet potatoes, and turnips. –Most have a sweet taste.
