in a plant cell you would find a cell wall
One in each cell.

Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.

The kind of cell would you expect to find the most mitochondira includes any aerobically active cell.
The organelle that you would expect to find in a plant cell but not animal cell is the centrosomes.
active cell
Well, I suppose that since mitochondria are the the main production centers of ATP and Active Transport requires ATP, that these two are directly proportional. The more mitochondria a cell has, the more ATP it can make, and the more it can do Active Transport

At any moment in time, at least one cell has to be selected in Excel. It is known as the active cell. There has to be a focal point so that data or formulas can be typed in. Even when more than one cell is selected, there is only one active cell. Which cell is the active cell can be changed at any time, but there always has to be an active cell. If there isn't then, before you do anything, you would have to make a cell active. Cells are fundamental to Excel so there has to be an active cell at all times.
