Plant Structures and Functions

Front

What part of the root allows water and minerals to enter?

Back

Root hairs are tiny extensions of root cells that increase the surface area for absorption of water and minerals from the soil.

Front

What is the function of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling the plant to take in carbon dioxide and release oxygen.

Front

What three things does a plant need for photosynthesis?

Back

A plant needs sunlight, water, and carbon dioxide to perform photosynthesis.

Front

How does water enter the roots from the soil?

Back

Water enters the roots through osmosis, which is the movement of water from an area of higher concentration in the soil to an area of lower concentration in the root cells.

Front

Which plant part carries sugars and nutrients throughout the plant?

Back

Phloem is the vascular tissue responsible for transporting sugars and other nutrients from the leaves to other parts of the plant.

Front

What is the role of xylem in plants?

Back

Xylem is the vascular tissue that transports water and dissolved minerals from the roots to the rest of the plant.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the waxy cuticle's function on plant leaves?

Back

The waxy cuticle helps to reduce water loss from the leaf surface and provides a barrier against pathogens.

Front

What is the difference between active transport and passive transport in plants?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What is transpiration in plants?

Back

Transpiration is the process of water vapor loss from the plant's surface, primarily through stomata, which helps in nutrient transport and temperature regulation.
