CELL ORGANELLES
Cell is the structural and functional unit of the body
Various types of organelles are present inside the cell
Organelle= “little organ”
![Page 4: Welcome](https://reader033.vdocument.in/reader033/viewer/2022060121/55944f021a28ab3f6f8b47e1/html5/thumbnails/4.jpg)
Various components of the cell are enclosed by a membrane is called plasma membraneor cell membrane
All the components within the plasma membrane are called protoplasm
Components other than the nucleus in the protoplasm are known as cytoplasm

CELL MEMBRANE
Boundary of the cell.
Cell memberane.
Made of a phospholipid
bilayer.

NUCLEUS
Control center of the cell
Contains DNA
Surrounded by a double membrane
Usually the easiest organelle to see under a
microscope
Usually one per cell

ENDOPLASMIC RETICULUM
Connected to nuclear membrane
Highway of the cell
Rough ER: studded with ribosomes; it makes proteins
Smooth ER: no ribosomes; it makes lipids

RIBOSOME
Site of protein synthesis
Found attached to rough ER or
floating free in cytosol
Produced in a part of the nucleus
called the nucleolus

GOLGI BODIES
Looks like a stack of plates
Stores, modifies and packages proteins
Molecules transported to and from the
Golgi by means of vesicles

LYSOSOMES
Garbage disposal of the cell
Contain digestive enzymes that break down
wastes
![Page 12: Welcome](https://reader033.vdocument.in/reader033/viewer/2022060121/55944f021a28ab3f6f8b47e1/html5/thumbnails/12.jpg)
CENTROSOME
Aids in cell division
Usually found only in animal cells
Made of microtubules
![Page 13: Welcome](https://reader033.vdocument.in/reader033/viewer/2022060121/55944f021a28ab3f6f8b47e1/html5/thumbnails/13.jpg)
MITOCHONDRIA
“Powerhouse of the cell”
Cellular respiration occurs here to release energy for the cell to use
Bound by a double membrane
Has its own strand of DNA
