Intro to Cells 2022

The main difference between PROkaryotic and EUkaryotic cells is that

• one is alive and the other is not

• one has a nucleus and the other does not

• one makes proteins and the other does not

• one has a cell membrane and the other does not

One thing that both PROkaryotic and EUkaryotic cells have in common is

• they both have membrane bound (fancy) organelles

• they both have a nucleus

• they both have DNA

• they are ALWAYS unicellular

Prokaryotic cells do not have DNA.

• true

• false

An example of a prokaryotic cell is

• bacteria

• plant

• animal

• all of the above

The building blocks of all living things

• cells

• atoms

• proteins

• DNA

This organelle is a rigid outer layer that protects plant, bacteria, and fungus cells.

• Cell Membrane

• Cell Wall

• Nucleus

• Chloroplast 

What is one way in which all living things on Earth are alike?

• All living things have hair.

• All living things are made of cells.

• The cells of all living things have chloroplast.

• All living things can move.

The _____________ holds the DNA, and controls the functions of eukaryotic cells.

• Nucleus

• Nuclear Membrane

• Mitochondria

• Chloroplast

The _____________ is a gel-like fluid that fills plant and animal cells. It holds the organelles in place and gives each cell its shape.

• Cytoplasm

• Cell Membrane

• Cell Wall

• Chloroplast

What can only be found in plant cells?

• Cell membrane

• Nucleus

• Chloroplast

• Mitochondria
