Question 2

What is a cell?

Answer 2

The smallest unit that can live on its own

Question 3

Difference between prokaryotic and eukaryotic

Answer 3

Prokaryotic: Lack membrane-bound organelle, genetic material lays free in cytoplasm, simple

Eukaryotic: membrane-bound nucleus storing genetic material, membrane-bound organelles performing specific functions (nucleus, ribosomes, cell membrane), complex

Question 4

What is a membrane-bound organelle?

Answer 4

Organelles protected from cytoplasm by an outer layer (found in eukaryotic cells)

Question 5

What are the four macro molecules?

Answer 5

Carbs (energy), Lipids (energy storage), Proteins (diverse functions), nucleic acid (genetic material)

Question 6

What is cellular respiration?

Answer 6

Process in which cell obtains ATP

Question 7

Why do cells need ATP?

Answer 7

ATP is the currency of the cell - main energy source

Question 8

What are some other needs of the cell?
