Answer:

Cell

Explanation:

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

Cytoplasm

Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. ... All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.

Cell Membrane

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures

Nucleus

The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes

CELL~

A cell is a structural and functional part of a body.

CYTOPLASM~

The cytoplasm is a jelly-like and semi-solid substance made up of mainly salts,water and organic molecules. Cytoplasm holds the organelles in the cell. All the life functions take place in the cytoplasm.

CELL MEMBRANE~

All the organelles of a cell like cytoplasm and nucles are enclosed within the cell membrane also called the plasma membrane. The cell membrane seperates the cell from its surroundings and also one cell from the other. The main function of the cell membrane is to regulate entry and exit of substances in the cell. It is a thin, flexible and selective permeable membrane.

NUCLEUS~

The nucleus is also known as "brain of the cell", nucleus is an important component of the cell. It acts as the control center for all the activities of the cell. The nucleus is spherical in shape and situated in the centre of the cell.
