What if....? (photosynthesis)

What would happen if the roots of a plant are cut off?

• The plant won't be able to absorb sunlight.

• The plant won't be able to absorb carbon dioxide from the air.

• The plant won't be able to absorb oxygen from the air.

• The plant won't be able to absorb water.

• The plant could continue the photynthesis process without problems.

What would happen if all the stomata in a plant stop working and can't open?

• The plant won't be able to absorb sunlight.

• The plant won't be able to absorb carbon dioxide from the air.

• The plant won't be able to absorb oxygen from the air.

• The plant won't be able to absorb water.

• The plant could continue the photynthesis process without problems.

What would happen if a plant loses all its chlorophyll?

• The plant won't be able to absorb sunlight.

• The plant won't be able to absorb carbon dioxide from the air.

• The plant won't be able to absorb oxygen from the air.

• The plant won't be able to absorb water.

• The plant could continue the photynthesis process without problems.

What would happen if a plant loses all its flowers?

• The plant won't be able to absorb sunlight.

• The plant won't be able to absorb carbon dioxide from the air.

• The plant won't be able to absorb oxygen from the air.

• The plant won't be able to absorb water.

• The plant could continue the photynthesis process without problems.

Rodrigo is making an experiment in which he grows a plant outside in the garden and another plant inside a dark closet.

What is the most probable result of this experiment?

• Both plants should grow similarly.

• Both plants should die because they cannot do photosynthesis.

• The plant in the garden should grow less because it is exposed to cold weather.

• The plant inside the closet should grow less because there is no sunlight.

Gabriela is doing an experiment in which she covers all the leaves of a plant with a dark paper. She waits for several weeks and the plant eventually died. What is the most probable explanation for this result?

• The plant had an excess of temperature due to the dark material.

• The plant could not do photosynthesis because the leaves could not absorb sunlight.

• The plant could not do photosynthesis because the leaves could not absorb water.

• The plant could do photosynthesis, but the glucose could not be stored correctly.

• The plant coukd not do photosynthesis because the leaves could not absorb oxygen.

A student made the following experiment. Why did the first plant died?

• The first plant did not have enough carbon dioxide to produce glucose and survive.

• The first plant did not have enough oxygen to produce glucose and survive.

• The first plant did not receive enough sunlight to do photosynthesis.

• The first plant receives an excess of sunlight.

Alicia does an experiment in which she puts the roots of a plant in a red colored water. After some days she notices that the leaves turn red.

What is the most probable explanation for this result?

• Because the leaves absorb water.

• Bacause the roots absorb water.

• Because the stem absorbs water.

• Because the stem carries the water from the roots to the leaves.

• Because the plant loses the chlorophyll pigment.
