CYTOPLASM

The cytoplasm is the gel-like substancresiding between the cell membranholding all the cell's internal sustructures (called organelles), excefor the nucleus. All the contents of thcells of prokaryote organisms (whic

lack a cell nucleus) are containewithin the cytoplasm. Within the celof eukaryote organisms the contents the cell nucleus are separated from thcytoplasm, and are then called th

nucleoplasm. The cytoplasm is abo80% water and usually transparent.

NUCLEUSIn cell biology, the nucleus (pl. nucle

from Latin nucleus or nuculeumeaning kernel) is a membranenclosed organelle found eukaryotic cells

It contains most of the cell's genetmaterial. Nuclear transport is crucito cell function, as movemethrough the pores is required fboth gene expression an

chromosomal maintenance. Tnucleus is the control center of thcell.

In cell biology, an organelle is

specialized subunit within a cell that ha specific function, and is usuaseparately enclosed within its own libilayer. Organelles are identified microscopy, and can also be purified

cell fractionation. There are many tyof organelles, particularly in eukaryocells. Prokaryotes were once thought to have organelles, but some examphave now been identified.

Eg. MITCHONDRIA

In cell biology, a mitochondrio

(plural mitochondria) is a membranenclosed organelle found in moeukaryotic cells. These organelles rangfrom 0.5 to 1.0 micrometer (m)diameter. Mitochondria are sometim

described as "cellular power plantbecause they generate most of the celsupply of adenosine triphosphate (ATPused as a source of chemical energy. addition to supplying cellular energ

mitochondria are involved in a range other processes

The Golgi apparatus, also known as thGolgi complex or Golgi body, is aorganelle found in most eukaryotic cellIt was identified in 1898 by the Italiaphysician Camillo Golgi and named afthim. Part of the cellular endomembransystem, the Golgi apparatus packagproteins inside the cell before they are seto their destination; it is particularimportant in the processing of proteins fsecretion.

The smooth endoplasmic reticulum (SER) has functions in severmetabolic processes, including synthesis of lipids and steroidmetabolism of carbohydrates, regulation of calcium concentration, drudetoxification, attachment of receptors on cell membrane proteins, an

steroid metabolism. It is connected to the nuclear envelope. Smooendoplasmic reticulum is found in a variety of cell types (both animal anplant), and it serves different function

Lysosomes are cellular organelles thcontain acid hydrolase enzymes to bredown waste materials and cellular debrThey can be described as the stomach of tcell. They are found in animal cells, whtheir existence in yeasts and plants adisputed. Some biologists say the same roare performed by lytic vacuoles, while othesuggest there is strong evidence thlysosomes are indeed in some plant celLysosomes digest excess or worn-oorganelles, food particles, and engulf virusor bacteria.

PLANT CELL ANIMAL CELL

A large central vacuole. A cell wallcomposed of cellulose and hemicellulose,pectin and in many cases lignin, is secretedby the protoplast on the outside of the cellmembrane.

An animal cell is a form of eukaryotic cthat makes up many tissues in animals. Tanimal cell is distinct from other eukaryotemost notably plant cells, as they lack cwalls and chloroplasts, and they hasmaller vacuoles.
