A. A chloride ion moves across the plasma membrane from a higher to lower concentration inside the cell.
Explanation:
Diffusion is the movement of particles from a region of higher concentration to that of lower concentration. Sometimes diffusion may require energy input to drive it.
- In facilitated diffusion, the concentration gradient creates the drive that fosters the diffusion.
- A membrane allows for the movement of tiny particles of matter across two regions.
- When the concentration in a region is above that of another, particles will move from the area having high concentration to that with a lower concentration till they both attain uniform concentration.
- This is known as facilitated diffusion.

Answer:
True.
Explanation:
The life of a plant alternates between haploid and diploid generations. From a fully matured diploid plant (2n) which is known as sporophytic generation a lot of spores which are haploid are produced by the process of meiosis. By the process of mitosis, these spores then develop into new multi-cellular plant which is also haploid just like spores (n), this phase of plant life cycle is known as gametophytic phase. This haploid plant is capable of producing gametes (n) which are also haploid. When two such gametes from the same or different plant fuse with each other a diploid cell is produced which is known as zygote (2n). This zygote subsequently divides and grows into a diploid plant which is a part of sporophytic generation. This is how the entire life cycle of various plants alternate between gametophytic and sporophytic phase.
This diploid plant then later again produces spores and the cycle of reproduction goes on in the same manner as described above.
