Respiration increases
Question 13 (1 point)
When looking at a stalk of celery that has been sitting in red food colored
water. Sarah notices the celery has red lines running through it. Why is this
possible?
Question 13 options:
The roots absorbed the water.
The stomata allowed the water in.
The xylem transported the water through the stem and to the leaves of the plant.
The phloem transported the water through the stem and to the leaves of the plant.
Question 14 (1 point)
If you forget to water a houseplant for a few a days, would its stomata be open or closed?
Question 14 options:
Open to allow water loss
Closed due prevent water loss
Question 15 (1 point)
This specialized cell controls gas exchange and water loss in a plant. It is found on the under-side of leaves. This structure is called a —
Question 15 options:
chlorophyll cell
chloroplast cell
stomata; guard cell
Question 16 (1 point)
Living Organisms need energy to carry on their life processes. Green plants get this energy by undergoing photosynthesis.
During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?
Question 16 options:
sugar
minerals
hydrogen
all of the above
Question 17 (1 point)
What is one reason why transpiration is important in plants?
Question 17 options:
It produces food from the sugar in the plant cells.
It enables the flow of water out of the plant.
It produces carbon dioxide in the leaves of the plant.
Question 18 (1 point)
Plants are green because of chlorophyll, the main photosynthetic pigment in chloroplasts.
Question 18 options:
True
False
Question 19 (1 point)
What type of energy is necessary for photosynthesis to occur?
Question 19 options:
heat
mechanical
electrical
sunlight
Question 20 (1 point)
Organelles found in plant cells that function through respiration to produce energy from oxygen and sugar are called —
Question 20 options:
Chloroplasts
guard cells
photosynthons
mitochondria
Question 21 (1 point)
A green plant must be able to perform three different processes in order to survive. What are they?
Question 21 options:
respiration, perspiration, photosynthesis
transpiration, respiration, photosynthesis
chlorophyll, photosynthesis, perspiration
transcription, photosynthesis, chloroplast
Question 22 (1 point)
Melissa is designing an experiment to learn what a plant needs to survive. She buys four plants of the same type. Then, she puts two in the light by the window and two in her closet where there are no windows
Finally, she gives the plants either no water or 100 milliliters ofwater every week for a month.
