Green plants produce their own food during photosynthesis. Which of these statements about photosynthesis is true?

Oxygen is one product of photosynthesis.

Water is one product of photosynthesis.

Chlorophyll is one product of photosynthesis.

Carbon dioxide is one product of photosynthesis.

Plant A and Plant B were identical when the investigation began and were given the same amount of water and fertilizer. The most likely explanation for the differences in plant growth is that light –

is needed for plant growth and development

is not as important as fertilizer

How do organisms get the energy they need?

Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.

Plants get energy from fertilizers, and animals get energy by drinking water.

Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.

Plants do not require energy because they do not move, and animals get energy by performing exercise.

What is the advantage for a plant to produce broad leaves compared to narrow needle-like leaves?

Broad leaves provide more surface area for water loss.

Broad leaves provide more surface area for gas exchange.

Broad leaves provide more surface area for light capture.

A severe thunderstorm moved through Dallas producing wind speeds in excess of 60 mph. It stripped all the leaves from the seedlings in its path. These seedlings eventually died. What probably caused the deaths of these young trees?

The trees died due to lack of energy.

Heavy rainfall caused severe flooding which drowned the trees.

The wind damaged the trees’ roots, so they were not able to absorb water and nutrients from the soil.

The weakened trees were attacked by insects; which caused them to die.

According to the diagram, Product 2 is -

oxygen produced by photosynthesis

carbon dioxide produced by photosynthesis

carbon dioxide produced by respiration

A student placed a flower in a vase but forgot to add water. The picture above shows the flower’s appearance after a few days. What force/s contributed to the flower’s appearance?

loss of turgor pressure and gravity

Which question is this apparatus most likely designed to answer

Does geotropism affect the growth of a plant?

Does turgor pressure affect the absorption of water?

Does phototropism affect the growth of a plant?

Do plants exhibit fight or flight reactions?

Which of these equations does the diagram support?

Water + Carbon dioxide + Sunlight = Glucose + Oxygen

Oxygen + Water + Sunlight = Carbon dioxide + Glucose

Glucose + Water + Sunlight = Carbon dioxide + Oxygen

Carbon dioxide + Glucose = Sunlight + Water + Oxygen
