The greater the surface area of a cell, the faster the cell can transport materials across its membrane because there is more area to absorb/excrete materials. We also want the surface area much higher than the volume of a cell. the more volume a cell has the slower the transport of diffusion will be. If the cell is smaller because it has a higher surface area than it does volume. Because of this larger SA:V ratio, smaller cells will transport materials faster.
Lipids contain more energy than carbohydrates because they contain more carbon to hydrogen bonds.
They release carbon dioxide into the atmosphere which in effect create green house gasses
Answer is A. It cant be B because they are to close together and it cant be C because some of the seeds are also to close together. Hope this helps!! :)
