Intro to Bio: Photosynthesis Recap

The outer surface of the leaf has a thin waxy covering.

• blade

• cuticle

• petiole

• epidermis

Most chloroplast cells are found in the

• upper epidermis

• palisade mesophyll layer

• lower epidermis

• stomata

The water needed for photosynthesis comes into the leaves through the

• upper epidermis
• stomata
• guard cells
• xylem cells

The important gases, carbon dioxide and oxygen, enter and leave the leaf through the

• upper epidermis
• phloem
• stomata
• guard cells

Sugar and the products of photosynthesis move through the plant in 

• the phloem cells
• the xylem cells
• the root hair cells
• palisade mesophyll layer

What is letter "D" pointing to?

• upper epidermis

• palisade mesophyll

• spongy mesophyll

• bundle sheath

Carbon dioxide and oxygen enter and leave the leaf through the

• upper epidermis

• phloem

• stomata

• guard cells

In which leaf tissue does photosynthesis occur?

• mesophyll

• phloem

What role do pigments play in photosynthesis?

• Make plants green
