2.2 - How do pieces of the cell support life? (Review)

How do you change the Cell Theory?

• Discovering new evidence

• Proving that you are correct

• Giving ideas based on your opinion

• Testing the hypothesis

Where does a cell come from?

• Pre-existing cells

• Emerged from the ground

• Remains of dead organisms

• Bacteria and viruses

What is the main function of large central vacuole in plants?

• If with enough water, it causes the cell to become more rigid and creates structural support to the plants

• It provides shelter for ATP inside the cell

• It protects the DNA from foreign materials that enter the cell

• With a good amount of sunlight, it will produce food

Mitochondria have double-membrane system. What is the main function of the inner membrane?

• To provide protection for the ATP  inside the cell

• To provide large space area for the production of ATP

• To create design and to make it more appealing

• To instruct the proteins to make more ATP

Inside the nucleus is the DNA which carries the instruction to make protein, it needed to be delivered to the ribosome to synthesize the protein. Why is the rough ER located near the nucleus?

• to protect it

• to allow the ribosomes to make proteins more efficient

• to give aesthetic to the cell

• to get better directions in producing ATP

Active transport uses ATP to facilitate the movement of molecules against the concentration gradient.

• True

• False

Which characteristics are shared by all cells?

• Cell wall and cell membrane

• Genetic material and ribosome

• Genetic material and chloroplast

• Mitochondria and chloroplast

• Prokaryotic-1

What are the characteristics of plant?

• Surrounded by a rigid coat of cellulose

• Contains mitochondria and chloroplast

• Has DNA and cell wall

• Has flagella and cilia
