Section 1: “Cell Structure
Pages 38 – 40
COMMON CELL TRAITS
• A cell is the smallest unit that is capable of
performing life functions.
COMPARING CELLS
• The size & shape of
a cell relates to its
function. (job it does)
Prokaryotic Cells
(proh KAYR ee yah tihk)
• cells without membranebound structures
• EX: bacteria
pond scum
Eukaryotic Cells
(yew KAYR ee yah tihk)
• cells with
membrane-bound
structures
• EX: animals, plants,
fungi and protists
CELL WALL
•
•
•
•
protects the cell
gives shape
is made of cellulose
A cell wall is found in plants, algae, fungi,
& most bacteria.
CELL MEMBRANE
• Outer covering, protective
layer around ALL cells
• For cells with cell walls,the
cell membrane is inside the
cell wall
• Allows food, oxygen, &
water into the cell & waste
products out of the cell.
CYTOPLASM
• gelatin-like inside cell membrane
• constantly flows
• aka protoplasm
NUCLEUS
• Directs all cell
activities
• Contains instructions
for everything the cell
does
• These instructions are
found on a hereditary
material called DNA
• Usually the largest
organelle
CHLOROPLASTS
• Green organelles that
make food
• found only in plant cells
CHLOROPHYLL
• A green pigment that
gives leaves & stems
their color
• Captures sunlight energy
that is used to produce
food called glucose
• Glucose is a type of
sugar
MITOCHONDRIA
• Organelles that release
energy from food
• This energy is released
by breaking down food
into carbon dioxide
• AKA the powerhouse b/c
they release energy from
food
• Some muscle cells have
20,000 mitochondria
VACUOLES
• Temporary storage
spaces
• Store food, water,
waste
