Biology--Cells

cells and functions

The cell theory states that...

All cells are made from pre-existing cells
All organisms are made of cells
Cells are the basic unit of life

Cell Membrane

controls what goes in and out of the cell

Nucleus

controls cell activites and is involved with reproduction and protein synthesis

Cytoplasm

fluid of the cell, allows organells to float and move in the cell

SER

involved in lipid sythesis, used in detoxication and a storage of calcium ion

Ribosomes

protein production

Golgi Apparatus

packages materials for the cell

Vacuoles

fluid filled sacs, store wastes or food, larger in plant cells

Mitochondria

Powerhouse of the cell, ATP, sit of respiration where energy is released

Chloroplast

site of photosyntehsis where food is made

Cell Wall

protects and supports in cell in plant cell

Lysosomes

small vesicles that contain enzymes and chemicals tha thelp digest materials brought into the cell and also breaks it down

Capsule

provides protection

plasmid

circular, double stranded confer antiboiotics

Cell Envelope

boundry between internal and external environiment

Pili or Pilus

used in hollow tubes for conjugation

Microtubles

structure and tracks for moving materials

Centersome

cell devision and mitoioc spindles

Peroxisome

oxidative organelles, breaks down hydrogen perixide into water and is a catalase

Cytosol

the liquid component in cytoplasm

Nucleolus

ribosome production

Micro and intermdediate filaments the cytoskeleton

microfilaments, provides support and structure amoeboid movement

Secretory Vesicles

allow for secretion and are nuero transmitters

RER

protein sythesis and attaached meaning ready for export and free meaning used within
