What are the outputs of respiration
carbon dioxide, glucose and oxygen
oxygen, carbon dioxide and water vapor
carbon dioxide, glucose and energy
carbon dioxide, energy, and water
Plants are able to carry out photosynthesis because of the organelle known as the mitochondria.
True
False
What conclusion can be drawn about respiration based on the chart shown.
Plants release more gas when they are closer to light
plants release less gas when they are closer to the light
the plant that is 40 cm from the light makes the most bubbles
plants release more gas when they are far away from the light
What is the role of stomata during photosynthesis?
allow oxygen into the leaf and to release carbon dioxide
allow carbon dioxide into the leaf and release oxygen
allow water vapor into the leaf to make sugar
release water from the leaf
The image shows the opening and closing of the stomata. What structure is responsible for opening and closing the stomata?
guard cells
xylem cells
guard chloroplast
chlorophyll
Which of the below is not true of photosynthesis?
some of the sugar is turned into other compounds, such as cellulose
some of the sugar is stored in the plants cells for later us
the waste product carbon dioxide is given off through tiny openings in the underside of the leaf
the products are used by both plants and animals
For transpiration to occur, what part of the leaf must be open in to allow the release of excess water?
guard cells
roots
stomata
xylem
Martha was trying to identify a weed in her garden. She made the following observations about the weed listed below. Which of her observations supports the inference that photosynthesis can take place in the weed she found?
it had a smooth stem
it had a rough, dry texture
it was green in color
Plant cells lose water through transpiration. Which of the following processes keep the plant from drying up completely?
stomata release water vapor
guard cells open the stomata
the stomata take in oxygen
guard cells close the stomata
Plants take in carbon dioxide through openings in their leaves known as________.
guard cells
xylem
stomata
chloroplasts
Cacti live in a very dry environment and need to store water that they are able to collect. Which explanation best describes a catus?
stomata would be closed during the day to prevent water loss and open at night to allow the entry of needed gases.
stomata open and close whenever they want.
during the day they keep their stomata open so they don't lose water and closed at night because the temperature is cooler.
What are the outputs of photosynthesis?
Sunlight, carbon dioxide and water
sunlight, oxygen and glucose
glucose and oxygen
energy, oxygen and carbon dioxide
Water being absorbed by the roots, pulled up to the leaves and then released into the air through the stomata is an explanation of what plant process?
transpiration
condensation
photosynthesis
respiration
What process converts sugar into energy, allowing the plant to grow and develop?
mitosis
respiration
photosynthesis
transpiration
What are the three things a plant needs in order to go through the process of photosynthesis?
glucose, oxygen and water
water, carbon dioxide and sunlight
sunlight, oxygen, and carbon dioxide
oxygen, carbon dioxide and water
What are the inputs of photosynthesis?
Sunlight, carbon dioxide and water
sunlight, oxygen and glucose
glucose and oxygen
energy, oxygen and carbon dioxide
What are the inputs for the process of respiration?
water and carbon dioxide
glucose and carbon dioxide
oxygen and carbon dioxide
water vapor and sunlight
Oxygen is a product of cellular respiration.
true
false
Which of the below represent the raw materials of photosynthesis?
carbon dioxide and oxygen
carbon dioxide and water
glucose and oxygen
water and oxygen
During plant respiration, oxygen in the air combines with glucose. The sugar is broken down and produces what three products?
nitrogen, oxygen and water vapor
carbon dioxide, energy, and water vapor
water vapor, glucose, and energy
