The concentration of carbon dioxide is higher outside a plant leaf than inside a plant leaf. What will happen?
Select one:
a. Carbon dioxide diffuses away from the plant
b. Carbon dioxide concentrations do not change
c. Carbon dioxide diffuses into the plant for photosynthesis
d. Carbon dioxide diffuses out of the plant for photosynthesis
I think its c. Help me please.
"When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. Water vapour also diffuses out of the stomata."
sorry if this doesn't help;-;. I found it on google. bbc.co.uk bitesize
Oh thank you :) I'll let you know if its correct. i'll put c
It was all correct! Thank you sooo much! :D
To determine the correct answer, we need to understand the process of diffusion and the role of carbon dioxide in plant photosynthesis.
Diffusion is the movement of particles (in this case, carbon dioxide molecules) from an area of high concentration to an area of low concentration. In this scenario, the concentration of carbon dioxide is higher outside the plant leaf than inside. When there is a concentration gradient like this, diffusion occurs to equalize the concentrations.
In the context of photosynthesis, plants utilize carbon dioxide from their surroundings to produce glucose and oxygen. This process occurs in specialized structures called chloroplasts within the plant cells, specifically in the green pigment-containing cells called mesophyll cells found in the leaf.
Given that the concentration of carbon dioxide is higher outside the plant leaf, it means there is a higher concentration gradient, with carbon dioxide molecules outside the leaf moving towards lower concentrations inside the leaf. Therefore, the correct answer is option c: Carbon dioxide diffuses into the plant for photosynthesis.
As a result, the carbon dioxide molecules will enter the plant leaf through tiny pores called stomata, which are present on the leaf's surface. Inside the leaf, the carbon dioxide will be used by the plant for photosynthesis, along with sunlight and water, to produce glucose and release oxygen as a byproduct.
So, when the concentration of carbon dioxide is higher outside a plant leaf than inside, carbon dioxide will diffuse into the plant for photosynthesis.
