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)

Question 18 options:

True

False

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

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.
