Comparing Cell Types
What are some main differences between these two cells?
• Stores and protects genetic
information
• Makes sure the DNA is available
for use at al times
• Enclosed in a double membrane
called the nuclear envelope
• Inside the nucleus is the
nucleolus – the site where
ribosomes are housed for
making protein
Smooth ER –
No Ribosomes
Rough ER
Studded with
Ribosomes which gives
it a bumpy look
Ribosomes – made of protein
and RNA
site of protein synthesis
Found in the ER and suspended
in the cytoplasm
• Consists of closely layered stacks
of membrane-enclosed spaces
• Processes, sorts and
delivers proteins
• Supplies energy to the
cell by converting the
food you eat into useable
energy
• Has its own ribosomes
and DNA just like the
nucleus
• Contain enzymes
• Can engulf and digest targets molecules:
This helps the cell:
1. Defend cells from invading bacteria
and viruses
2. Break down damaged or worn-out
cell parts
• Small region of
the cytoplasm
that produces
microtubules
• Contains
centrioles
• Cylinder-shaped
organelles made up
of microtubules
arranged in a circle
• Divide DNA during
cell division
Chloroplasts:
Cell walls:
• Provide rigid support
and give the cell its
shape
• Carry out photosynthesis
• Made up of sacs that
contain chlorophyll – a
light absorbing molecule
that gives plants their
green color
• Have their own DNA and
Ribosomes like the nucleus
and mitochondria in
animal cells
