Leaf Pogil

How would the cuticle and stomata work together to maintain the leaf's function

Both of these structures can open and close to determine what goes in/out

During the time that stomata are closed, gases cannot enter or leave. Explain how this would affect the plant's ability to do photosynthesis.

Certain gases (carbon dioxide) could not enter the cell for photosynthesis

What might plant cells do with the sugars made during photosynthesis

Plants use sugars as their won wood to make energy

The green color of chloroplasts is due to a pigment in them that absorbs light energy. Knowing this, infer which layer inside a leaf gives the whole leaf its green color. Write on complete sentence to express your reasoning.

The chloroplasts reflect the green color onto the epidermis

In grammatically correct sentences, trace the path of the reactants for photosynthesis as they enter the leaf

Water and sunlight enter the leaf through the vein. Carbon dioxide enters the leaf through the stoma of the leaf.

In grammatically correct sentences, trace the path of the products of photosynthesis as they exit the leaf

Water in the form of gas and oxygen exit the leaf through the stoma. Sugars exit the leaf through the phloem in the vein.

What would be the advantage to having no chloroplasts in the cells of the spongy mesophyll

all of the chloroplasts would be in the palisade mesophyll where the sunlight is

How would you describe this structure

empty space for entering/exiting on the underside of leaf

How does the placement of veins help to carry out their function of transporting materials to and from the leaf

it helps to efficiently spread out all materials because of its location in the leaf

How would this affect the ability of the leaf to retain water especially in dry conditions

it would allow the plant to shrivel up and water could escape it easily

What are the reactants for photosynthesis

light, carbon dioxide, water

What gases might you find inside the air spaces

oxygen, carbon dioxide, and water vapor

List 3 substances leaving the leaf

oxygen, water, sugars

Remembering the function of chloroplasts, in which of the leaf is photosynthesis taking place

palisade mesophyll

Which kinds of cells have chloroplasts in them

palisade mesophyll, guard cells

what is the purpose of having a water-tight covering

so that all of the parts of the plant will stay together and it keeps it from dehydrating

What structure is found between guard cells

stoma

From where do the products leave the leaf

stoma (underside of the leaf)

What are the products of photosynthesis

sugars and oxygen

What components in photosynthesis are matter

sugars, water, carbon dioxide, oxygen

What components in photosynthesis are energy

sunlight

What is the general position of the vein

the center of the leaf

Through which layer does light energy travel to reach the palisade mesophyll

the cuticle and the upper epidermis

Suggest a way in which the stoma and guard cells arrangement might work to control the amount of water that is leaving the leaf

the guard cells protect the opening in the stoma and monitor what comes in/out like a gate

What is the relationship between the stoma and an air space

the stoma and air space connect and they are both empty spaces, the stoma also is an opening to the air space

How would the cylindrical shape of the palisade mesophyll cells increase the amount of photosynthesis that the leaf can carry out

there can be more of them because they can pack many more chloroplasts

Suppose there were many chloroplasts in the cells of the upper epidermis. How would that change the amount of sunlight reaching the chloroplasts in the palisade layer

there would be less sunlight because of the thick layer above it

List at least 3 differences between the cells of the palisade mesophyll and the cells that make up the other areas within the leaf

these contain chloroplasts, are closely packed, and are perpendicularly shaped

Considering its locations and your previous knowledge of the word, what do you think might be the function of the epidermis

to protect the cell and keep everything in place

List the layers of the leaf starting at the upper cuticle all the way to the lower cuticle

upper cuticle, upper epidermis, palisade mesophyll, spongy mesophyll, lower epidermis, and lower cuticle

Where do these reactants enter the leaf

vein

Which substance is both entering and leaving

water

Where might water be stored for later use in the process of photosynthesis

water can be stored in the vein

How does water change between its entry and exit

water enters as a liquid and leaves as a gas

List 3 things entering the leaf in Model 1

water, sunlight (in the form of light energy), and carbon dioxide
