Prokaryote vs. Eukaryote

Based on complexity of the cell, does this appear to be eukaryotic or prokaryotic?

• Prokaryotic

• Eukaryotic

• not enough information

• neither

Answer explanation

This cell has DNA, but it is free-floating (not in a nucleus). It is also missing "membrane bound" organelles like mitochondria. It is PROKARYOTIC

Based on the complexity of this cell, do you think it is prokaryotic or eukaryotic?

• prokaryote

• eukaryote

• both

• neither

Answer explanation

This cell has a nucleus and many membrane bound organelles. It is a EUKARYOTE.

This cell is a plant cell. What organelles does it contain that supports this claim? Check all that apply - there are 3!

• cell wall

• chloroplasts

• mitochondria

• cell membrane

• very large vacuole

Answer explanation

An animal cell would not have the following: very large vacuoles, chloroplasts, or cell walls.

Which organelle below is NOT membrane bound?

• endoplasmic reticulum

• ribosome

• nucleus

• mitochondria

• chloroplast

Answer explanation

Ribosomes are found in both eukaryotes and prokaryotes, therefore we know they are not membrane bound (since they're also in prokaryotes!)

Which organelle below is found in prokaryotes?

• endoplasmic reticulum

• ribosome

• nucleus

• mitochondria

• chloroplast

Answer explanation

Every organelle in this list except ribosomes are membrane bound organelles, therefore not found in prokaryotes.

DNA is found in both prokaryotes and eukaryotes. What is different in how each cell contains its genetic material?

• DNA is contained in the nucleus in prokaryotes, and free floating in the cytoplasm in eukaryotes

• DNA is contained in the nucleus in eukaryotes, and free floating in the cytoplasm in prokaryotes

• DNA in prokaryotes is composed of different nucleotides than DNA in eukaryotes

• Prokaryotes do not contain their own genetic material, and eukaryotes do

Prokaryotes cannot make their own energy because they do not have membrane bound organelles. Eukaryotes can make their own energy. Which organelle makes energy in eukaryotes, out of oxygen and sugar?

• chloroplast

• mitochondria

• ribosomes

• nucleus

Prokaryotes have cytoplasm.

• True

• False

All eukaryotes have cell walls.

• True

• False

Both eukaryotes and prokaryotes have ribosomes, because they are not a membrane bound organelle.

• True

• False
