Photosynthesis - What's in a Leaf? POGIL

Front

Where does most photosynthesis occur in a leaf?

Back

Palisade mesophyll - This layer contains chloroplasts and is where most of the photosynthesis takes place.

Front

Which layer of the leaf serves as protection against damage, much like your skin?

Back

Epidermis - The outer layer of cells that protects the leaf from physical damage and pathogens.

Front

Which layer of the leaf protects the leaf from dehydration?

Back

Cuticle - A waxy layer that prevents water loss from the leaf surface.

Front

How is water transported within the leaf?

Back

Central vein - Also known as the midrib, it contains vascular tissues that transport water and nutrients.

Front

How does carbon dioxide enter the leaf?

Back

Stomata - Small openings on the leaf surface that allow gas exchange.

Front

What is the primary function of chloroplasts in leaf cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy.

Front

What role do stomata play in photosynthesis?

Back

Stomata allow carbon dioxide to enter the leaf and oxygen to exit, facilitating gas exchange.

Front

What is the function of the palisade mesophyll?

Back

The palisade mesophyll is responsible for most of the photosynthesis due to its high concentration of chloroplasts.

Front

What is the purpose of the cuticle in leaves?

Back

The cuticle helps to reduce water loss and protect the leaf from environmental damage.

Front

What is the difference between the palisade mesophyll and sponge mesophyll?

Back

Palisade mesophyll is tightly packed for maximum light absorption, while sponge mesophyll has air spaces for gas exchange.
