3.5 Plants

Front

What is the cuticle in plants and what is its function?

Back

The cuticle is a waxy layer that covers the surface of leaves and stems, helping to prevent water loss and protect the plant from environmental damage.

Front

What tissue type is primarily responsible for photosynthesis in plants?

Back

The ground tissue is where most photosynthesis occurs, containing chloroplasts that capture sunlight.

Front

What are guard cells and what role do they play in plant physiology?

Back

Guard cells are specialized cells that surround stomata and regulate their opening and closing to facilitate gas exchange while minimizing water loss.

Front

What is the primary function of plant roots?

Back

The primary function of roots is to absorb water and minerals from the soil, anchoring the plant and providing stability.

Front

What is xylem and what is its role in plants?

Back

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

Front

What is the role of phloem in plants?

Back

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

Front

How do stomata function in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they open to let in carbon dioxide and close to reduce water loss.

Front

What is transpiration and why is it important for plants?

Back

Transpiration is the process of water vapor loss from plant leaves, which helps to cool the plant and maintain nutrient flow from roots to leaves.

Front

What adaptations do desert plants have to minimize water loss?

Back

Desert plants often have thick cuticles, reduced leaf surface area, and specialized structures like spines to minimize water loss.

Front

What is the significance of chlorophyll in plants?

Back

Chlorophyll is the green pigment in plants that captures light energy for photosynthesis, allowing plants to convert sunlight into chemical energy.
