CELL ORGANELLE

Cell Membrane/Cell Wall

• surrounds cytoplasm of living cells
• protects interior contents in the cell

PHOSPHOLIPID BILAYER

• physically separates organelles
• regulation of transport into and out of cells and organelles
• cell to cell recognition
• cell to cell communication

Untitled Slide

Cytoplasm

• protector/barrier that is made of lattes, that are connected together
• main purpose is to hold together the organelles within the cytoplasm
• it is the substance that fills the cell.

Untitled Slide

Cytoskeleton

• helps the cell with shape, support, and movement
• mediates movement by helping the cell move in its environment

Untitled Slide

THREE MAIN STRUCTURAL COMPONENTS

• microtubules: composed of alpha and beta tubulin; fairly strong
• actin filaments: composed of G-actin proteins
• intermediate filaments: composed of keratin; resist tension

Untitled Slide

RIBOSOME

• read and translate a cell's genetic code
• then it replicates the proteins that the code represents

Untitled Slide

FLAGELLUM and Cilium

• moves liquid past surface of the cell

Untitled Slide

Nucleus

• regulates all cell activity
• controls the enzymes that are present

Untitled Slide

MITOCHONDRIA

• production of energy

Untitled Slide

CHLOROPLASTS

• produces food

Untitled Slide

LYSOSOME

• break down waste materials
• hold enzymes that digest excess organelles

Untitled Slide

GOLGI APPARATUS

• processes and packages macromolecules
• this happens after synthesis & before it makes it way to its destination

Untitled Slide

SMOOTH ENDOPLASMIC RETICULUM

• creates storage for the organelle
• important in creation of storage for steroids

ROUGH ENDOPLASMIC RETICULUM

• important for the synthesis and packing of proteins

Untitled Slide

VESICLES

• breaks down substances in cell
• breaks them into smaller molecules

Untitled Slide

CENTRAL VACUOLE

• storage bubbles that are found in the cell
• might store food
• might store waste
• will store anything to keep cell satisfied
