Transpiration

Front

What are guard cells?

Back

Guard cells are specialized cells that control the opening and closing of stomata, regulating gas exchange and transpiration in plants.

Front

What adaptation helps plants survive in desert environments?

Back

Small leaves help reduce water loss through transpiration, making them beneficial for plants in arid conditions.

Front

What is palisade mesophyll?

Back

Palisade mesophyll is a layer of cells in the leaf where most photosynthesis occurs, typically located just below the upper epidermis.

Front

What is the primary function of roots?

Back

Roots primarily take in water and nutrients from the soil and anchor the plant to the ground.

Front

How does increasing leaf area affect transpiration?

Back

Increasing leaf area generally increases the transpiration rate due to a larger surface area for water vapor to escape.

Front

What is transpiration?

Back

Transpiration is the process by which water vapor is released from plant leaves into the atmosphere, primarily through stomata.

Front

What role do stomata play in plants?

Back

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

Front

What is the cuticle in plants?

Back

The cuticle is a waxy layer on the surface of leaves that helps reduce water loss by providing a barrier to evaporation.

Front

What is the relationship between transpiration and photosynthesis?

Back

Transpiration helps to cool the plant and maintain nutrient flow, while also facilitating the uptake of carbon dioxide needed for photosynthesis.

Front

What factors can affect the rate of transpiration?

Back

Factors include temperature, humidity, wind speed, and light intensity, all of which can influence the rate at which water vapor is lost.
