Leaf Disk Lab /Stomata Lab Flashcard

Front

What is the process by which plants convert carbon dioxide and water into glucose and oxygen using sunlight?

Back

Photosynthesis

Front

What is the main function of stomata in leaves?

Back

To allow gases to move rapidly in and out of leaves.

Front

What is transpiration?

Back

The diffusion of water vapor out of a leaf.

Front

What are the reactants needed for photosynthesis?

Back

Carbon dioxide and water.

Front

If 18 leaf discs are floating after 12 minutes, what is the rate of discs per minute?

Back

1.5 discs/minute.

Front

Which arrow in a leaf diagram typically indicates the direction of carbon dioxide diffusion on a sunny day?

Back

Arrow D.

Front

What is the role of chlorophyll in photosynthesis?

Back

To capture sunlight.

Front

Define diffusion in the context of gas exchange in plants.

Back

The movement of gas molecules from an area of higher concentration to an area of lower concentration.

Front

What is the significance of leaf structure in photosynthesis?

Back

The structure maximizes light absorption and gas exchange.

Front

What is the relationship between stomata and transpiration?

Back

Stomata facilitate transpiration by allowing water vapor to exit the leaf.
