HOW WELL DO YOU
KNOW
THE CELL?
Nucleus
Contains DNA - chromosomes
2 membranes surrounding it, the
envelope/membrane
Controls all of the cell’s activities –
including information needed to make
proteins
Microtubules
Part of cytoskeleton
Hollow tubes made of tubulin
Hold organelles in place, maintain a cell’s
shape, & act as tracks that guide
organelles and molecules as they move
through the cell
Ex. cilia, flagella, centrioles
Cell Membrane
Covers cell surface
Determines what enters or exits the cell
– selectively permeable
Prokaryotic
Cell that lacks a nucleus and membrane
bound organelles
Bacteria and Archea
Hooke
First person to identify and name cells –
coined the term “cell”
Microfilaments
Part of cytoskeleton
Long threads made of actin
Changes cell shape, especially during
muscle contraction
Allows movement of cytoplasm within the
cell (cytoplasmic streaming)
Rough ER
Transports materials within or out of
the cell
has ribosomes attached
produces phospholipids and proteins
Golgi Bodies/Apparatus
Stacks of flattened, membranous sacs
Many proteins and lipids pass from ER
to here for final modifications;
Like a POST OFFICE - modifies,
packages and secretes various
molecules
Lysosomes
Contain digestive enzymes to break
down large molecules as well as nonfunctioning cell parts and cells
Small, membrane-bound organelles
formed by Golgi complex
Leeuwenhoek
Looked at living cells in pond water;
invented first mini-microscope
Centrioles
Used in cell division
Seen in animal cells
Ribosomes
Site of protein synthesis
Can be free (in cytoplasm) or bound
(attached to ER)
Produced in nucleolus
Made of RNA and proteins
Smooth ER
Transports materials within and out of
the cell
Functions in lipid synthesis ex.
cholesterol
No ribosomes attached
Eukaryotic
Type of cell with a true nucleus and
membrane bound organelles
Plant, protists, animal and fungi
Mitochondria
Transfer energy from organic molecules
(like glucose) to ATP (cellular energy)
Muscle cells have lots of these
Nicknamed the POWERHOUSE
Inner folds called cristae to increase
surface area
Plant Cell
Type of cell with a cell wall, chloroplasts
and a large central vacuole
Virchow
Stated cells come from the division of
preexisting cells
Cytoskeleton
General term to describe the structures
that give cells internal organization,
shape, and ability to move
Cell Wall
Made of cellulose
Protects, prevents excess H2O
uptake, maintains shape of plant
cell
Animal Cell
Type of cell with lysosomes and
centrioles
Lack a cell wall
Chloroplasts
Use light energy to make carbohydrates
from CO2 and H2O
Contains chlorophyll
Responsible for photosynthesis
Vacuole
Stores water, enzymes, wastes, and
other materials
Largest organelle in a plant cell
Schleiden
Stated all plants are made of cells
Schwann
Stated all animals are made of cells
Cell Theory
All living things are composed of cells
Cells are the basic units of structure and
function in living things
All cells come from preexisting cells
Chromosomes
Structures that form when DNA
supercoils around proteins
Organizes DNA for cell division
Chromatin
Uncondensed/uncoiled DNA
DNA present in this form when the cell
is not dividing
Vesicle
Stores and moves materials between cell
organelles (ie. Rough ER to golgi)
Moves materials to and from the cell
membrane
Cilia
Short, hair-like projections found on the
outside of cells
Used for movement
Flagella
Long, tail-like projections found on the
outside of cells
Used for movement
Cytoplasm
Jelly-like material found between the
cell membrane and the nucleus
Contains the organelles of the cell
Nucleolus
Found inside of the nucleus
Makes ribosomes
