Types of RootsFibrous Roots Taproot
Roots that are smaller One large root that grows straight down
They grow in many directions It has smaller roots that branch off of it
Examples: grass, marigolds, most trees Examples: 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 StemsGreen Stems Woody Stems
Thin, green, and bend easily Brown, woody, and do not bend easily
Produce their own food Grows thicker and taller each year
Examples: tulips, lilies, petunias Examples: 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.

Dormancy: The state of much lower activity
Why do trees enter a state of dormancy?– There is less sunlight for photosynthesis– To save energy
