Roots serve several important functions for plants. They provide anchorage and support, absorb water and nutrients from the soil through osmosis, and store food to allow plants to survive dormant periods. There are different types of roots including primary, secondary, tap, lateral, fibrous, and adventitious roots. The external structure of roots includes the root cap, root tip, and root hairs, while internally roots contain tissues like the epidermis, cortex, endodermis, pericycle, phloem, and xylem. Students are expected to learn the parts and functions of roots as well as how to identify different root types as part of understanding how plants develop and can be grown effectively.
