Organelles
Cell Wall
Functions:
-protects and supports plant cells
-prevents water loss
-made of cellulose
Location: outer layer of plant cells
Factory = exterior walls, sub floor and roof
Body = not in animal cells
Cell MembraneFunctions:
-protects the cell, barrier
-controls materials that go in and out of the cell
Location: around the cell
Factory = ceiling, floor, doors and windows
Body = our skin with pores
CytoskeletonFunctions:
-support structure of cell
-prevents cell collapse
-aids in movement
-made of Microtubules (thin hollow) & Microfilaments (thin solid) network
Location: Inside the cell
Factory = interior walls, poles…
Body = our bones
CYTOSKELETON
Functions:-control center-largest organelleLocation: inside the cell, near the center
Factory = Main boss’s officeBody = our brain
Nucleus
Nucleolus (Nucleoli)Function:-makes ribosomesLocation: inside the nucleus (dark spot)
Factory = CEO or boss manBody = cerebrum of the brain
Nuclear MembraneProtects nucleusLets things in/out of nucleus (pores)Location: around nucleus
RiobosomesFunction:
-makes proteins
-float free or attached
-smallest & most numerous
Location: in cytoplasm or
attached to E.R.
Factory = secretary, memos, gophers
Body = nerves of the nervous system
Endoplasmic Reticulum (E.R.)Function:-series of folded membranes
-makes & transports proteins
-two types: smooth & rough (w/ ribosomes)
Location: attaches from cell membrane to nuclear
membrane
Factory = machines that make
a product
Body = stomach
MitochondriaFunctions:
-makes energy/powerhouse
-has a double membrane
-turns sugar to ATP
Location: in cytoplasm
Factory = electric power,
generator
Body = lungs & heart
Mitochondria
Functions:-smooth folded membrane packages proteins and secretes waste Location: in cytoplasm
Factory = packaging part of assembly lineBody = lg. & sm. intestines
Golgi complex (or apparatus)
Golgi Apparatus
ChloroplastsFunctions:
-traps sun’s energy and
makes food (photosynthesis)
-full of chlorophyll
Location: in plant cells
Factory = vending machine
Body = we don’t have
Lysosomes
Functions:
Contains digestive enzymes
Destroys bacteria, old cell parts…
Location: in cytoplasm
Factory = inspectors, janitors
Body = liver & kidneys
Functions:-stores food and water-has digestive enzymes-plants have a large one usuallyLocation: in cytoplasm
Factory = warehouse of goods Body = kidneys
Vacuoles
Few Extra Cell Structures
Cytoplasm
Gel-like substances, holds all
organelles in cell
Location: in cell
Centrioles
-Helps the cell to divide
Location: in cytoplasm
