Plant Systems 22/23

Why are plant important? (Select all that apply)

• Vital to all life on Earth

• Producers & main support for food webs

• Produce oxygen via photosynthesis

• Create chloroplasts needed to make mitochondria

These plants transport food and water through the xylem and phloem.

• vascular

• nonvascular

Plants transport water from the ____up to the ____.

• shoots, roots

• roots, shoots

Water, ​ (a)   , and other important nutrients need to be ​ (b)   from one part of a plant to another. This is done via the ​ (c)   that take in water and the ​ (d)   that produce sugar that are transported to the rest of the plant through ​ (e)   tissues.

Which of the following describes the xylem?

• The plant stem, leaves, and buds, also contains vegetative and reproductive parts of plants.

• Anchors the plant and absorbs nutrients and water; typically underground.

• Carries sugars (food made by plant) to feed the plant

• capable of absorbing sunlight and transferring that solar/light energy to the chloroplast

How does water travel from the roots to the plan leaf? Name the structure that carries water.

• stomata

• phloem

• chloroplast

• xylem

Which transport tissue allows water to travel upward from the roots to the leaves?

Which statement best explains the importance of the root hairs to the stems and leaves of the plant?

• Root hairs convert minerals into glucose for immediate use by cells.

• Root hairs decrease the need for osmosis and diffusion in vascular tissue.

• Root hairs prevent water loss in leaves through transpiration and gas exchange.

• Root hairs increase the surface area of the roots for nutrient and water absorption.
