Extra Parts of Plant Cells compared to Animal cells

Cell Wall

Chloroplasts

Permanent Cell Vacuoles

Structure of Bacteria Cells

Peptidoglycan Cell Wall

Cell membrane

Cytoplasm

Ribosomes

Circular DNA

Plasmids

Flagella

Function of Nucleus

Contains DNA (genetic information) which controls the activities of the cell

Function of Cytoplasm

Gel like substance composed of water and dissolved solutes

Supports the internal structures of the cell

Site of many chemical reactions (including anaerobic respiration)

Function of Cell Membrane

Holds the cell together separating the inside of the cell from the outside

Controls which substances enter or leave the cell (partially permeable)

Function of Ribosomes

Found in Cytoplasm

Site of protein synthesis

Function of mitochondria

Site of aerobic Respiration

Function of cell wall

Made of cellulose in plants, peptidoglycan in bacteria

Gives extra support defining its shape

Function of chloroplasts

Contains the Green Chlorophyll pigment that absorbs light energy for photosynthesis

Function of Permanent Cell Vacuole

Contains Cell sap, solution of sugar and salt

Used for storage of certain materials

Helps to support the shape of the cell

Functions of Plasmids

Small rings of DNA that contain extra genes to those found in the circular chromosome

Function of Flagella

Long thin whip like tails attached to bacteria that allow them to move

How are new cells produced

Cell division

Specialized cells are cells with

Specific Functions

Function of ciliated cells

Movement of mucus in the trachea and bronchi

Function of root hair cells

Absorbtion

Function of palisade mesophyll cells

Photosynthesis

Function of neurons

Conduction of electrical impulses

Function of red blood cells

Transport of Oxygen

Function of sperm and egg cells

reproduction

Cells

Basic functional and structural units in a living organism

Tissues

Groups of cells or similar structure working together to preform the same function

Organs

Made from different tissues working together to preform specific functions

Organ systems

Groups of organs with related functions, working together to preform body functions
