The Mitochondria
Active transport takes place in the small intestine, where nutrients are absorbed from the intestine and into the bloodstream. More specifically, it is the structures known as villi that contain the protein receptors necessary for active transport to take place. The process also happens in the nephrons of the kidneys, where glucose and water/ions are selectively reabsorbed back into the bloodstream.
If a cell is actively performing functions that require energy, such as muscle cells during exercise, it will likely have more mitochondria to meet the increased energy demand. Mitochondria are the powerhouses of the cell, responsible for producing ATP through aerobic respiration, so more active cells typically have more mitochondria to support their metabolic needs.
The Brain cell structures are different from the basic animal cell. The brain cells has more functions than the basic animal cell
It means it need more energy. So it is a very active cell. Examples are muscle cells,cardiac cells
The structures allow the cell to perform specific functions.
If the muscle cell in question is part of a muscle the active person uses regularly, the cell will be bigger and have more nuclei than a less active muscle cell.
If you select one cell, it will be active. However, if you select multiple cells at once, only one can be the active cell. That is usually the cell you select first.
Plant
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.

active transport
It can be referred to as the current cell or the active cell or just the selected cell.
The active cell is the one that is currently selected. Into it you can type something, so it is for typing data or a formula into. Even if more than one cell is selected, only one is the active cell and it will show in a different colour to the other selected cells. The active cell can also be used to enter something and put it into the other selected cells.
It has more cell structures
The active cell is the cell that the cursor is on or the cell where whatever you type appears.
