Mitochondria (09:13) This is where energy is derived from carbohydrates, fats, and other fuels and is converted into adenosine triphosphate or ATP, which is like the main currency that drives life in Eukaryopolis.
A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell's DNA. It is also where most RNA is made.

What is a cell? A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.
All living organisms (whether they are bacteria, archaea or eukaryote) share several key characteristics, properties or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation (including homeostasis), energy processing, and evolution with adaptation.
Answer: The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life".
Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
The nucleus of a cell is like your parents. Your parents control most of things that take place inside your house. The cytoskeleton of a cell can be compared to the walls of a house. The walls of a house are similar to the cytoskeleton of a cell because they provide support for a house.
The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant. Golgi apparatus is like the fuel pump on a car. The fuel pump pushes the fuel to the carburetor like the golgi apparatus pushes/sends the package.
A cell is the smallest unit of life and is capable of all living functions. Cells are the building blocks of life. This is the reason why cells are referred to as the basic structural and functional units of life. All cells vary in their shape, size, and activity they perform.
a. Cell is the smallest unit of life. They are the structural, functional and biological uits of life. The discovery of cells was first made by Robert Hooke. While examining a section of a cork under the microscope, he observed small compartment-like structures and named them cells.
Cells: The cell is the basic structural and functional unit of life. All living organisms are made up of cells. Cells make tissues, tissues make organs, organs make organ systems and organ systems make a living organism. Thus, the cell is the building block, or the structural unit of the living body.
Sickle-cell anemia is a genetic disease where the blood cells aren't in their correct doughnut-like shape, and they are more of a crescent moon (or sickle) shape. They can't carry oxygen very well. People with sickle-cell anemia are usually tired, or dizzy, and it can be painful in the heart.
They also replicate independently and more frequently than the cells that contain them. This means they can accumulate quite a lot of errors and since there is no crossing with the father's mitochondrial DNA, there is no way to get rid of the errors.
