NY Regents Adaptations for Photosynthesis

In addition to the green plants, ​ (a)   algae carry on photosynthesis.

Algae are found both in the oceans ( ​ (b)   ) and bodies of freshwater.

They are responsible for a large percentage of ​ (c)   products found on Earth

• marine
• photosynthetic

Although photosynthesis may occur on all parts of the plant, the organs which are most highly adapted for this process are:

• Leaves

• Stems

• Roots

• Cuticle

Which part of the plant creates a large surface area to absorb light

• Leaves

• Stems

• Roots

• Cuticle

The waxy outer covering that protects the internal tissues of the leaf from excessive water loss, and resistance to invasion by fungi is:

• Leaves

• Roots

• Stems

• Cuticle

Openings in the cuticle and epidermis are called ​ (a)   . Their size is regulated by ​ (b)   .

Stomates ​ (c)   of Oxygen, Carbon dioxide, and Water inside and outside of the cell.

• allow the exchange
• stomates
• guard cells

Using the picture:

On a hot humid day the plant does not want to lose too much water to transpiration (evaporation in plants), how would the stomate look like to preserve water?

• Picture on left

• Picture on right

Imagine the stomates as a top secret government building,

which part of the stomate would open and close the door just like a government building?

• Guard cell

• stroma

• Chloroplast

Look at the picture:

What layer are the chloroplast located, and what part of the leaf is most of the photosynthesis occurring.

• Palisade cells

• Cuticle

• epidermis

• Spongy cells

What part below the palisade cells are air spaces where gases are circulated?

• Spongy cells

• Cuticle

• Palisade cells

• Chloroplast

Conducting tissue, located in the ​ (a)   of the leaves, the ​ (b)   carries water and minerals up to the leaves. Food from the leaves is brought down by the ​ (c)   tissue to the other plant organs.

• veins
• xylem
• phloem
