What role does water play in the survival and growth of plants?

Root hairs increase the surface area for absorption of water and minerals. Describe how this process occurs.

Fill in the blank: Xylem vessels are long, tube-like dead cells that consist only of ___ and an empty interior.

Cell walls

True or False: Xylem vessels contain living cells with cytoplasm and a nucleus.

False. Xylem vessels are composed of dead cells with no cytoplasm or nucleus.

Riddle: I transport water from the roots to the leaves, and I have no living cells in my body. What am I?

Xylem vessels

After water is absorbed by root hair cells, what is the next step in the water transport process?

After absorption by root hair cells, water moves inward across the root to the xylem vessels.

Fill in the blank: Root hairs are ___ but visible without a lens.

Microscopic

Explain how minerals such as magnesium and nitrate ions are absorbed by plants.

Which part of the plant's water transport system is located at the center of the root?

Xylem vessels

Multiple Choice: What happens to the end walls of xylem vessels?

What role do xylem vessels play in plants?

Xylem vessels transport water from the roots to the leaves and other parts of the plant.

Fill in the blank: In roots, xylem is located ___ to facilitate water transport from root hairs to the stem.

Centrally

True or False: Transpiration involves the absorption of water vapor by leaves.

False. Transpiration is the loss of water vapor from leaves.

What process allows water to move from the xylem vessels into leaf cells?

Water moves from xylem vessels into leaf cells through diffusion.

Riddle: I help in cooling, support, and transport, but most of me evaporates. What am I?

Water

How does water exit the leaf once it has been used by chloroplasts?

Water exits the leaf by evaporating into air spaces and then diffusing through stomata.

Fill in the blank: Xylem vessels in trees typically have diameters around ___ mm.

0.05

What is the significance of stomata in the process of transpiration?

Stomata are tiny holes that allow water vapor to diffuse from the leaf into the air.

Multiple Choice: Which of the following is NOT a function of water in plants? A) Support B) Photosynthesis C) Energy production D) Transport

C) Energy production

What happens to most of the water that enters leaf cells during photosynthesis?

Most of the water is not retained and is lost through transpiration.

What role does water play in maintaining the structural integrity of plant cells?

Fill in the blank: Water is a reactant in photosynthesis, combining with carbon dioxide to produce ___ and oxygen.

Glucose

True or False: Excretion refers to the elimination of all waste materials from the body.

What are the main types of waste substances that are excreted by the human body?

Riddle: I help plants stay tall and strong, but without me, they wilt and don't belong. What am I?

Water
