3.2 Functions of Cell Organelles (NEW VERSION)

Microtubules and Micro-skeleton

Name two types of fibers that make up the cytoskeleton

microfilaments

These are tiny threads that allow the cell to move and divide.

microtubules

long and hollow, acts as "tracks" for the movement of organelles

nucleus

stores and protects the cells genetic information (DNA, Chromosomes)

Rough Endoplasmic Reticulum (RER)

processes and transports proteins made at attached ribosomes

ribosomes

site of protein synthesis

Golgi apparatus

process and package proteins

mitochondria

supplies energy to cell by converting glucose into ATP

vacuole

larger storage of materials for cell

lysosome

contain enzymes that break down viruses, bacteria, and waste

Centrioles

small cylinder shaped organelles that aids in cell division

cytoplasm

jelly like substance that fills the cell and contains dissolved molecular building blocks

cell membrane

determines what can go in or out of the cell

nucleolus

makes ribosomes

vesicle

short term storage for the cell

Smooth Endoplasmic Reticulum (SER)

this area makes lipids

Chromosomes

threadlike structures made of DNA molecules that contain the genes

Chloroplast

An organelle found in plant and algae cells where photosynthesis occurs

cell wall

A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.

large central vacuole

found in plants, this organelle stores water for the cell
