Unit 2 - Plant Survival

Front

What is the function of phloem in plants?

Back

Phloem is responsible for transporting sugars and other metabolic products downward from the leaves.

Front

What is transpiration in plants?

Back

Transpiration is the process by which water evaporates from the surface of plant leaves, helping to draw water up from the roots.

Front

What are stomata and where are they located?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, including the release of oxygen and the intake of carbon dioxide.

Front

Why is it important for plants to have room to grow?

Back

Plants need room to grow so their roots can spread out and absorb nutrients and water from the soil.

Front

How do stomata help in water regulation for plants?

Back

Stomata can open and close to regulate water loss through transpiration, helping to maintain hydration in the plant.

Front

What role do roots play in plant survival?

Back

Roots anchor the plant in the soil and absorb water and nutrients necessary for growth.

Front

What is the significance of leaf structure in photosynthesis?

Back

The structure of leaves, including their surface area and arrangement of chloroplasts, maximizes light absorption for photosynthesis.

Front

How does water movement through a plant occur?

Back

Water moves through a plant via the xylem, from the roots to the leaves, driven by transpiration and capillary action.

Front

What environmental factors can affect transpiration rates in plants?

Back

Factors such as temperature, humidity, wind speed, and light intensity can influence the rate of transpiration.

Front

What adaptations do plants have to minimize water loss?

Back

Plants may have adaptations such as waxy cuticles, reduced leaf surface area, and specialized stomata to minimize water loss.
