Cell Organelles

Vyanna Melvin PD1

Plasma or Cell Membrane

Structure-Made of a phospholipid bilayer. The phospholipid has one head and two tails.

Function- Some membrane proteins sit on the face. Others are anchored in the membrane have pieces.

Plants, Animals or Both - Animals

Cell Wall

Structure -A rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants,fungi, and bacteria. In the algae and higher plants, it consists mainly of cellulose .

Function- helps plants keep its shape

Plants ,Animals or Both-Plants

Cytoplasm

Structure- a fluid that fills a cell

Function-it fills the cells dissolved enzymes

Plants , Animals or Both - Plants

Nucleus

Structure - big dark spot some in the middle of cytoplasm

Function- provides a site for genetic transcription

Plants, Animals or Both - Both

Nuclear membrane

Structure- two lipid bilayers

Function- To act as a barrier that seperates

Plants, Animals or Both-Both

Nucleolus

Structure- The fibrillar center, dense component

Function- Assembles ribosomes

Plants,Animals or Both-Animals

Centrioles

Structure- tube like structures that aid in cell division

Function- organize materials to produce micro tubes

Plants ,animals or Both- Animals

Chromatin

Structure-the complex of DNA

Function-organizes eukaryotic genomes

Plants,Animals or Both- Plants

Ribosomes

Structure-Celluar machine which is highly complex

Function- workhouses of protein bio synthesis

Plants ,Animals or Both- Both

Golgi apparatus

Structure- factory type

Function- modifying,sorting and packaging of proteins

Plants, Animals or Both- Both

Endoplasmic reticulum

Structure- Jelly like cytoplasm

Function- folding of protein molecules

Plants,Animals or Both- Animal

mitochondria

Structure- shaped perfectly to maximize productivity

Function- •outer membrane- covers organelle

•Inner membrane- folds over constantly

Plants, Animals or Both- Both

chloroplast

Structure- green plant cell found in higher plants

Function- they participate in plant immune response as they lack immune cells

Plants,Animals or Both-Plants

lysosomes

Structure- cellular organelles that contain hydrolase

Function-digest excess or waste out organelles, food, etc

Plants,Animals or Both- Animals

peroxisomes

Structure - long fatty acids converted to medium chains

Function - break down the fatty acids

Plants,Animals or Both - Both

vacuole

Structure - enclosed compartments

Function- isolating materials that might be harmful or a threat to the cell

Plants ,Animals or Both-Both

Cytoskeleton

Structure- the frame for cells

Function provides an important structural framework for cell shape

Plants,Animals or Both-Both
