50% it said i need more words hope this helps have a nice day.
Cell surface or membrane is made of phospholipid bilayer with embedded proteins and sugars. Cell membrane acts as a barrier between cell and its external environment but it is also responsible for the communication with other cells and transport of molecules inside and outside the cell. It is selectively permeable to ions and molecules (some of them pass through the membrane easily, while others require transport proteins or channels). There are 4 ways of molecule transport:
1. Diffusion – no energy required
2. Facilitated transport – transport proteins included
3. Active and co-transport – energy required
4. Vesicle transport (exocytosis and endocytosis)
Microvilli are extensions of cell membrane that increase its surface for diffusion.
Different types of cell junctions have a different influence on the membrane transport. For example, tight junctions are a barrier and the molecules are unable to pass through.
Answer 2: Chlorophyll is a green<span> pigment that gives most plants their color.The reason that it is </span>green<span> is because it absorbs other colors of light such as </span>red<span> and </span>blue<span>, so in a way the </span>green<span> light is reflected out since the pigment does not absorb it.

Answer:
Nutrient poor soil
Explanation:
Because rainforest have very poor infertile.The soil also contains Less organic.
Or for simple answers wet forest bad, dry and healthy forest is good.
Answer:
its gonna be D
Explanation:
It can't be A, since cells only divide once they are past interphase
It can't be B, becuase cell division does have an order
It can't be C, becuase a dying cell is still a functioning one
And it is D becuase daughter cells are haploid, while parent cells are diploid
