Types of Roots Fibrous RootsTaproot Roots that are smallerOne large root that grows straight down They grow in many directionsIt has smaller roots that branch off of it Examples: grass, marigolds, most treesExamples: Carrots, radishes, turnips What do roots do for plants? 1.Roots anchor the plants into the ground so they do not blow or wash away. 2.Roots also take in water and minerals from the soil.
Types of Stems Green StemsWoody Stems Thin, green, and bend easilyBrown, woody, and do not bend easily Produce their own foodGrows thicker and taller each year Examples: tulips, lilies, petuniasExamples: trees, shrubs What do stems do for plants? 1. Stems support the leaves, flowers, or cones. 2. Stems contain tubes that carry food, water, and minerals to all parts of the plant. 3. Some stems can store food for the plant.
BladeVeinStalk/Petiole Where photosynthesis takes place Transports water and minerals throughout the leaf Supports the leaf on the stem of the plant. Parts of a Leaf Stalk/Petiole Blade Vein
Vein Patterns PinnatePalmate
Broad-Leaved Plants SimpleCompound A single blade attached to a stalk. One stalk with several blades attached to it.
Dormancy: The state of much lower activity Why do trees enter a state of dormancy? – There is less sunlight for photosynthesis – To save energy
Transpiration: The giving off of water vapor by plants (excess water that leaves a plant)
