Animal Cell


generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy

Therefore is called the "powerhouse" of the cell

Also involved in a range of other processes, such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth

compartments or regions include the outer membrane, the intermembrane space, the inner membrane, and the cristae and matrix, which carry out specialised functions

outer and inner membranes composed of phospholipid bilayers and proteins

inner mitochondrial membrane is compartmentalized into numerous cristae, which expand the surface area of the inner mitochondrial membrane, enhancing its ability to produce ATP

the area of the inner membrane is about five times greater than the outer membrane for liver mitochondria


The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA

The genes within these chromosomes are the cell's nuclear genome

function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression — the nucleus is therefore the control center of the cell

The nuclear envelope consists of two cellular membranes, an inner and an outer membrane, arranged parallel to one another

Nuclear pores provide aqueous channels through the envelope


Are spherical organelles that contain enzymes (acid hydrolases)

digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria

The membrane around a lysosome allows the digestive enzymes to work at the 4.5 pH they require

fuse with vacuoles and dispense their enzymes into the vacuoles, digesting their contents

Plasma Membrane

surrounds the protoplasm of a cell and, in animal cells, physically separates the intracellular components from the extracellular environment

made of two layers of phospholipids

regulates what enters and leaves the cell. Many molecules cross the cell membrane by diffusion and osmosis

Endoplasmic Reticulum




Synthesise proteins from amino acids

DNA makes RNA, which then makes protein

Golgi Apparatus

The primary function of the Golgi apparatus is to process and package macromolecules, such as proteins and lipids, after their synthesis and before they make their way to their destination; it is particularly important in the processing of proteins for secretion, and forms part of the cellular endomembrane system

composed of membrane-bound stacks known as cisternae

integral in modifying, sorting, and packaging macromolecules for cell secretion (exocytosis) or use within the cell

primarily modifies proteins delivered from the rough endoplasmic reticulum but is also involved in the transport of lipids around the cell, and the creation of lysosomes

The transport mechanism which proteins use to progress through the Golgi apparatus is not yet clear


Used for storage, and usually contain water or food

Are enclosed compartments which are filled with water containing inorganic and organic molecules including various enzymes in solution, though in certain cases they may contain solids which have been engulfed

no basic shape or size, its structure varies according to the needs of the cell
