Plasama or Cell membrane

*The cell membrane controls the movement of substances in and out of cells.

*The basic function of the cell membrane is to protect the cell from its surroundings.

*It consists of the phospholipid bilayer with embedded proteins.

*It can be found in plants and animal.

Cell wall

*The cell wal is a very tough, flexible and sometimes fairly rigid layer that surrounds some types of cells.

*The cell wall provides shape to the many different cell types needed.

*It's found in plants.

Cytoplasm

*It is a special fluid.

*The special fulid fills up cells and is mostly made up of water and salt.

*It can be found and both animal and plant.

Big image

Nucleus

*The nucleus contains the DNA that determines the entire structure and function of that cell.

*The nucleus function is to maintain the integrity of these genes and to control the activities of the cell.

*It can be found in animal cells and plants.

Nuclear Membrane

*Surrounds the nucleus.

*The function is to act as a barrier that separates the contents of the nucleus from the cytoplasm.

*Found in both animals and plants.

Big image

Nucleolus

*The nucleolus is a non-membrane bound structure composed of proteins and nucleic acids.

*The function is to assemble ribosomes.

*Found in animals and plants.

Big image

Centrioles

*Centrioles structure is they are paired structures lying at right angles to one another.

*Function is cell divison.

*Only animals.

Big image

Chromatin

*Structure to organize DNA.

*The functions of chromatin are to package DNA into a smaller volume to fit in the cell.

*Found in both animal and plants.

Big image

Ribosomes

*Structure is composed of RNA.

*To link amino acids.

*Found in both animals and plants.

Big image

Golgi apparatus

*Golgi apparatus move by being built at the cis face and destroyed at the trans face.

*Function sorting and packaging of proteins for secretion.

*Found in both animals and plants.

Big image

Endoplasmic reticulum

*The structure is an extensive membrane network.

*The function folding of protein molecules.

*Found in both animals and plants.

Big image

Mitochondria

*The structure has 7 levels.

*Function It is where the citric acid cycle takes place

*Found in animals and plants.

Big image

Chloroplast

* Chloroplast are the sites of photosynthesis. These double-membrane bound organelles enclose additional membranes called thylakoids.

*The function absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.

*Only plants

Big image

Lysosomes

*The structure is stomach of the cell.

*The function is they are cellular organelles that contain acid hydrolase enzymes that break down waste materials and cellular debris.

*Found in animals and plants .

Big image

Peroxisomes

*The structure is they carry out oxidation reactions that break down fatty acids and amino acids.

*Function is the breakdown of very long chain fatty acids through beta-oxidation.

*Found in animals and plants.

Big image

Vacuole

*The organelle has no basic shape or size.

*The function is plants use cell walls to provide support and surround cells.

*Found in both animals and plants.

Big image

Cytoskeleton

*The cytoskeleton provides support in a cell.

*It is a network of protein fibers supporting cell shape and anchoring organelles within the cell.

*Found in both animals and plants.
