Photosynthesis (Honors Biology)

The following are parts of the chloroplast:

• stomata -- tiny pores that allow for gas exchange

• granum -- stacks of thylakoids

• stroma -- colorless fluid surrounding the thylakoid

• chlorophyll -- light absorbing pigment

Please identify the parts of a leaf:

• mesophyll -- spongy tissue inside the leaf

• chloroplasts -- photosynthetic pigment containing organelles

• Krebs cycle -- builds sugar from CO₂ and light reaction products

• stroma -- tiny pores that allow for gas exchange

The electromagnetic spectrum, specifically photons of visible light...

• are absorbed by different types of chlorophyll pigments and carotenoids.

• provide the necessary energy to run the light dependent reaction.

• are gathered by pigments in the chloroplast.

• are harvested by photosystems.

• Directly creates NADPH and O₂

Please select the correct relationships:

• Mitochondria + Food = Chemical Energy

• Chloroplast + Light = ATP + NADPH + O₂

• ADP + P = ATP via ATP Synthase

• Calvin Cycle + CO₂ = NADP⁺ + ATP + G3P

Plants have learned to adapt to hot and dry environments by...

• leaving their stomata closed during the day.

• banking CO₂ so that the plant can continue to undergo photosynthesis even without gas exchange.

• preventing water loss by closing their stoma.

• stopping the process of photosynthesis.

How does carbon dioxide get into the leaves of a plant?

• It's absorbed by the roots
• It's made in a chemical reaction in the stem
• It enters through the stomata
• It goes through the flowers
