4.1 Plants and Water Quizizz

What is the main purpose of root hairs in plants?

• To provide structural support for the roots

• To absorb water and minerals from the soil

• To store food and nutrients for the plant

• To release oxygen into the soil

Where do root hairs grow on the plant?

• On the leaves

• On the stem

• On the flowers

• On the surface of the roots

How do root hairs increase the surface area for water absorption?

• By increasing the number of roots

• By growing deeper into the soil

• By being very tiny, numerous cells

• By having a waxy coating to repel water

What is the main function of the xylem vessels in the plant?

• To transport water and minerals from the roots to the leaves

• To store food and nutrients for the plant

• To provide structural support for the plant

• To release oxygen into the air

How do xylem vessels transport water upwards in the plant?

• They use cellular respiration to pump the water up

• They have hollow, tube-like structures that allow unimpeded flow

• They rely on the root hairs to actively push the water up

• They create a suction force to pull the water up

What is the main role of the cell wall and cell membrane in the root hair cells?

• To provide protection and structure

• To allow water and minerals to move in and out

• To store food and energy for the plant

• To communicate with other root cells

What happens to the water and minerals after they enter the root hair cells?

• They are stored in the root hair cells

• They move towards the xylem vessels in the center of the root

• They are immediately transported to the leaves

• They are used to produce food for the plant

Why are the spaces between soil particles important for water absorption?

• They allow air to circulate around the roots

• They provide a pathway for the root hairs to grow

• They store water and minerals for the plant to use

• They prevent the soil from becoming too compacted

What is the diameter of a typical xylem vessel?

• About 0.5mm

• About 0.05mm

• About 5mm

• There is a range of xylem vessel diameters

How do xylem vessels differ from living plant cells?

• Xylem vessels have no cytoplasm or nucleus

• Xylem vessels are located in the roots only

• Xylem vessels are made of lignin and cellulose

• Xylem vessels are capable of photosynthesis
