The organelles of plant and animal cells Generalized plant cell Generalized animal cell

cell wall Provides structural support to the cell cell membrane

Semi-permeable Acts as a gatekeeper, controlling what can enter or leave the cell

cytoplasm The fluid matrix that holds all the organelles in place Composed of 80% water Location of many chemical reactions

Consists of the everything contained inside the cell membrane nucleus The nucleus controls the activities of the cell through the code stored in the DNA

The chromatin (which become visible as chromosomes during cell division) contains the DNA (genetic material) The nuclear membrane protects the DNA and allows transport of material in and out of the nucleus.

endoplasmic reticulum The endoplasmic reticulum (ER) is connected and continuous with the nuclear membrane and the cell membrane It forms a transportation network throughout

the cell ribosomes Produced by the nucleolus (in the nucleus) Create proteins which are the building blocks of many structures

Found in the cytoplasm and on some kinds of endoplasmic reticulum Golgi apparatus A series of folded membranes that packages and transports products Small membrane bound structures called

vesicles are pinched off and carry the materials out of the cell vesicles Membrane covered sacs produced by Golgi apparatus that store and transport

materials Can fuse with the cell membrane to transport materials out of the cell vacuole Vacuoles store:

food water wastes The central vacuole of a mature plant cell is often quite large Animal cells often have several small

vacuoles mitochondrion Create energy from food (glucose) chloroplast

The sites of photosynthesis (production of glucose from sunlight, water and CO2)
