The document provides information about human physiology and cell organelles. It defines the cell as the basic structural and functional unit of living matter. It then describes some of the key organelles found in animal cells, including the nucleus, which stores and duplicates genetic information; mitochondria, which generate ATP energy; the plasma membrane, which acts as a physical barrier and facilitates cell signaling and selective permeability; the Golgi apparatus, which modifies and packages proteins and lipids; lysosomes, which contain digestive enzymes; and the endoplasmic reticulum, which helps transport molecules within the cell. The document focuses on describing the basic structures and functions of these important organelles found within animal cells.

3. What is Cell?
The Cell is the structural and functional unit of
the living matter and is capable of carrying on
the processes of life independently.

Functions of The nucleus
▪ It serves the function of
information storage,
▪ retrieval and duplication of
genetic information.
▪ It is referred to as the brain of
the cell
Nucleus
8. Mitochondria
▪ Present in nearly all
types of human cell,
▪ They generate ATP,
▪ The energy currency of
the cell
▪ Signaling between cells
and cell death
9. Physical Barrier
The plasma membrane surrounds all
cells and physically separates from
the extracellular fluid outside the cell.
Cell Signaling
Facilitate communication and signaling
between cells.
Selectively Permeable
Only certain molecules can pass through
Plasma membranes.
