Ch 1l 2 part 1

Identify the leaf part.

• Stomates

• Guard cells

• Mesophyll

• Cuticle

Which picture shows the palisade layer?

• 
• 
•

Which picture shows the spongy layer?

Which picture shows the cuticle?

Which picture shows the epidermis?

• 
• 
•

The xylem and phloem together are know as

• vascular bundles.

• the mesophyll.

• stomates.

• guard cells.

Most of the photosynthesis in a leaf occurs in the

• mesophyll layer (palisades and spongy layers).

• epidermis.

• xylem and phloem.

• stomates.

Identify the leaf part.

• lower epidermis

• upper epidermis

• cuticle

• spongy layer

Which cells give room for gas exchange between the palisade tissue cells and the stomata?

• Xylem

• Phloem

• Epidermis

• Spongy mesophyll

The function of the cuticle is

• to prevent water from evaporating from the leaf.

• to allow for gas exchange at the top of the leaf.

• to transport water and dissolved minerals.

• to transport dissolved sugars.
