Cell Theory, Types, and Organelles

What is the FIRST part of the cell theory?

• All cells come from pre-existing cells.

• Cells are the unit of structure and function in all living things.

• All living things are made of cells.

• Cells are cool.

How did people view cells BEFORE the microscope was invented?

• With their eyes

• They'd never seen cells!

What are the main differences between prokaryotes and eukaryotes?

CHECK ALL THAT APPLY.

• Prokaryotes have NO nucleus.

• Prokaryotes have NO membrane-bound organelles.

• Eukaryotes DO have a nucleus

• Eukaryotes DO have membrane-bound organelles.

What is FALSE about prokaryotic DNA?

• It is circular.

• It floats freely in the cytoplasm.

• Sometimes it is called "the nucleoid"

• It is kept safe in a membrane-bound nucleus.

What is FALSE about eukaryotic DNA?

• It is linear

• It free-floating in the cytoplasm.

• It is protected by a membrane-bound nucleus

• The mitochondria and chloroplasts in a eukaryote also have DNA.

Check off all of the unique features of animal cells.

CHECK ALL THAT APPLY.

• Large, central vacuole

• Many, small vacuoles

• Centrioles

• Cell Wall

Check off all of the unique features of plant cells. CHECK ALL THAT APPLY.

• Large, central vacuole

• Centrioles

• Cell Wall

• Chloroplasts

Multicellular organisms can have specialized cells that do certain jobs. For example, muscle cells carry weight. Energy is needed to carry heavy weight. So, muscle cells probably have lots of __________ since these structures make energy.

• chloroplasts

• cytoplasm

• ribosomes

• mitochondria
