Download Cells and Their Organelles

Cell Membrane



Phospholipid bilayer
Separates inside of cell from environment
Maintains homeostasis via selective permeability
Cell Wall

Firm, protective structure that gives the cell its
shape in plants, fungi, most bacteria, and some
protists
Cytoplasm


Jelly-like substance in
the cell
Suspends and
protects organelles
Vacuole

Stores material within the cell
Ribosome

The sites of protein synthesis
Golgi Apparatus

Packages proteins for transport out of the
cell
Endoplasmic Reticulum



Network of
membranes found
throughout the cell
Smooth: stores
substances
Rough: synthesize
and package proteins
Central Vacuole


Store water for plants
Provide structure for plants when full
Chloroplast


Contains chlorophyll, a green pigment that traps energy
from sunlight and gives plants their green color
Site of photosynthesis
Mitochondria

Produces a usable form of energy (ATP)
for the cell
Nucleus


Controls all the cell functions in a
eukaryotic cell
Contains DNA
Nucleolus

Site where ribosomes are made
Nuclear Membrane

Keeps all of the chromatin and nucleolus
inside
Lysosomes

Digests excess or worn-out cell parts, food
particles and invading viruses or bacteria
using enzymes
Microtubules


Proteins that help define cell structure and
movement
Form part of the cytoskeleton
Nuclear Pores

Allows RNA and proteins to pass through
Centrioles

Help animal cells divide
