Answer:
Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.
Explanation:
undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.
Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.
Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

Because bryophytes do not have a vascular tissue they
D) grow close to the ground
Answer: Option C
Explanation:
These cells are soft because of its function. Gaseous exchange takes place by the help of these cells. Spongy mesophyll cells are covered by thin layer of water and are loosely packed.
This is because, during the day time when the plant is performing photosynthesis these cells allows the carbon dioxide into the mesophyll cells and the oxygen out of the plant body.
