Why mitochondria is known as powerhouse of cell?
Mitochondria are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP) the cell’s main energy-carrying molecule. … Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients.
Which is known as brain of the cell?
The cell membrane is found in all cells that separates the interior of the cell from the outside environment. So we can say that the nucleus controls the cell and acts as the brain of the cell.

Cells were first discovered by Robert Hooke in 1665. He observed the cells in a cork slice (dead cells) with the help of a primitive microscope. Leeuwenhoek (1674) with the improved microscope discovered the free-living cells in pond water for the first time.
How the first cell was made?
The first cell is presumed to have arisen by the enclosure of self-replicating RNA in a membrane composed of phospholipids (Figure 1.4). … Such a phospholipid bilayer forms a stable barrier between two aqueous compartments—for example separating the interior of the cell from its external environment.
