What is the primary function of root hairs in plants?
What is the primary function of root hairs in plants?
- To store carbohydrates and nutrients
- To provide structural support to the plant
- To absorb water and minerals from the soil (correct)
- To facilitate the transport of sugars
Which statement accurately describes xylem and phloem?
Which statement accurately describes xylem and phloem?

Study Notes
Plant Systems: Roots
- Root systems anchor plants in the ground and absorb water.
- Most plants have a root cap protecting the root tip.
- Root hairs are thin projections that increase water absorption.
- Two main types of root systems:
- Taproot: A thick, main root growing straight down (e.g., carrots).
- Fibrous root system: Many small roots spreading out (e.g., grass).
Plant Systems: Shoots
- Shoot systems are above ground parts of a plant.
- The stem is the main support structure, holding leaves and flowers.
- Stems support leaves for photosynthesis.
- Stems support reproduction by holding flowers.
Leaves
- Leaves are where photosynthesis occurs.
- Leaves come in various shapes and sizes.
- Flowers contain reproductive organs.
- Flowers often have brightly colored petals and pleasant smells.
Buds
- Buds are areas of new growth at the tips of stems and roots.
Plant Transport
- Roots and stems contain transport systems (xylem and phloem).
- Xylem tubes transport water and dissolved minerals from the roots to the rest of the plant.
- Xylem is dead tissue with thick walls for support.
- Phloem tubes transport sugar from leaves to other parts of the plant (for growth and storage) via a sugar solution.
- Phloem is made of living cells connected end-to-end, with pores between them.
- Root hairs increase surface area for water and mineral absorption.
- Water and minerals travel up from the roots in the xylem.
- Sugar(food) is made by photosynthesis in leaves and moved down to other parts of the plant through phloem.
- Vascular bundles contain both xylem and phloem in vascular plants.
- The epidermis is the outermost layer of cells in roots.
- The cortex is between the epidermis and the vascular tissue in a stem or root in some plants.
Plant Structure and Function
- The different parts of a plant (roots, stems, leaves, flowers) work together.
