Photosynthesis

Which organelle performs photosynthesis?

• Chloroplast

• Mitochondria

• My phone

Leaves look green because.....

• absorb green wavelengths of light

• reflect red and yellow wavelengths of light

• reflect green wavelengths of light

• absorb yellow and blue light making them green

Plants use ______ as food and a building block for growth.

• chlorophyll

• pigment

• glucose (sugar)

• Oxygen

Light-independent (aka Calvin Cycle) reactions take place in the stroma of which plant organelle?

• thylakoid membrane

• stomata

• chloroplast

• mitochondria

Plants are __________, they make their own food.

• Heterotrophs

• Autotrophs

• Mitochondria

• A black hole into an intergalactic void

What is the chemical formula for glucose?

If carbon dioxide is completely removed from a plant’s environment, what would you expect to happen to the plant’s production of Glucose?

• Glucose production will increase.

• Glucose will not be produced.

• The rate of glucose production will decrease .

• Fewer glucose will be produced at first, but then the plant will recover.

If we enclosed a plant in an air-proof bottle, what would happen to the rate of photosynthesis 

• Gradually slow down to zero because CO₂ is used up
• Shows a constant rate as long as the light remains on
• Gradually speeds up because O₂ builds up
• Gradually slows down because glucose builds up

Why would the rate of photosynthesis decrease at super high temperatures?

• Enzymes are denatured

• Enzymes do not have enough kinetic energy

Select all the products of Photosynthesis.

• $H_2O$ (Water)

• $CO_2$ (Carbon Dioxide)

• $O_2$ (Oxygen)

• Sunlight (Light Energy)

• $C_6H_{12}O_6$ (Glucose)
