Cell Structure and Function

The cell is the structural and functional unit of life, serving as the smallest unit that can carry out all essential processes necessary for living organisms.
Cells are responsible for various functions including metabolism, energy transformation, and reproduction.

Cell Division

All new cells arise through the process of cell division, specifically via mitosis or meiosis, where existing cells replicate their genetic material and divide.

Cell Membrane

Surrounding each cell is the cell membrane, also known as the plasma membrane, which functions as a selectively permeable barrier, regulating the movement of substances in and out of the cell.

Cell Walls

Plant cells, fungi, and certain prokaryotes (like bacteria) possess cell walls, which provide structural support and protection, differentiating them from animal cells that lack this feature.

Independent Existence of Cells

Cells can exist independently; single-celled organisms (prokaryotes and some eukaryotes) function autonomously, while multicellular organisms depend on the function and cooperation of their constituent cells.

Description

Test your knowledge on the structural and functional unit of life which is the cell. Learn about the different components of a cell, such as the plasma membrane, cell wall, and more. Understand the importance of cells in organisms' existence and growth.
