Vacuoles and Lysosome questions:

1. The tonoplast:

  1. stores food in the vacuole
  2. is the covering of the vacuole
  3. divides the cytoplasm from the vacuole
  4. balances pH
  5. is a type of vacuole

2. What is the significance of a vacuole in a cell?

The significance of the vacuole in plant cells allows the cell to maintain Homeostasis by controlling the turgor pressure. In animal cells, the vacuole is used for storing food and water as energy for the cell, and also for storing waste.

3. How does a food vacuole compare with a digestive vacuole?

A food vacuole takes in food from an outside source through endocytosis whereas a digestive vacuole digests and ejects the waste out of the cell through exocytosis.

4. Enzymes inside lysosomes are:

  1. protease
  2. nuclease
  3. phospholipase
  4. all of the above
  5. none of the above

5. What does a contractile vacuole do?

A contractile vacuole expands and contracts to pump out absorbed substances.

Nucleus:

1. The nuclear envelope:

  1. is a double lipid bilayer
  2. has an outer layer continuous with rough ER
  3. has nuclear pores
  4. a and c
  5. all of the above

2. Why is the nucleolus so significant inside the nucleus of a cell?

The nucleolus is very important because the cell needs proteins to survive, and the nucleolus manufactures ribosomes, which produce proteins.

3. Label the parts of the nucleus:

4. The types of RNA are:

  1. messenger
  2. transfer
  3. ribosomal
  4. a and b
  5. all of the above

5. The nucleus contains the most of:

  1. ribosomes
  2. genetic material
  3. lysosomes
  4. vacuoles
  5. mitochondria

Endoplasmic Reticulum and Golgi apparatus:

1. The difference between the rough ER and the smooth ER is:

  1. The rough ER is studded with lysosomes
  2. The smooth ER is longer than the rough ER
  3. The rough ER is studded with ribosomes
  4. The smooth ER has genetic material
  5. There is no difference!

2. What is the significance of the Golgi apparatus?

The Golgi apparatus is a very significant part of the cell because of its role in protein synthesis. The Golgi apparatus modifies the proteins delivered from the rough endoplasmic reticulum.

3. Label the following parts:

  1. Nuclear membrane
  2. Nuclear pore
  3. Rough endoplasmic reticulum
  4. Smooth endoplasmic reticulum
  5. Ribosome
  6. Macromolecules
  7. Transport vesicles
  8. Golgi apparatus
  9. Cis face of Golgi apparatus
  10. Trans face of Golgi apparatus
  11. Cisternae of lipids

4. There are this many types of endoplasmic reticulum:

  1. 1
  2. 2
  3. 3
  4. 4
  5. 5

5. The smooth endoplasmic reticulum does the following:

  1. Synthesis of lipids
  2. Metabolism of carbs
  3. Steroid metabolism
  4. Only a and c
  5. All of the above

Power Stations:

1. The following are parts of mitochondria:

  1. Matrix
  2. Intermembrane space
  3. Pores
  4. Only a and b
  5. Only b and c

2. What is the significance of mitochondria in cells?

Mitochondria are very significant in cells because they produce ATP, which is the cell’s chemical energy.

  1. Label the following parts of a chloroplast:

  1. Stroma lamellae
  2. Stroma
  3. Thylakoids/ Granum
  4. Outer membrane

4. The group that all plastids are derived from is:

  1. Leucoplast
  2. Chromoplast
  3. Etioplast
  4. Proplastid
  5. Chloroplast
  1. What is a chloroplast responsible for?

A chloroplast is responsible for photosynthesis and starch formation.

Cytoskeleton:

1. The cell wall is:

  1. a membrane of the cell
  2. a wall of cells
  3. the outermost covering of the cell
  4. a and c
  5. all of the above

2. What is the significance of cilia and flagella in a cell?

The significance of cilia and flagella is to allow the cell to move itself. Without these organelles, the cell wouldn’t be motile.

3. Locate the flagella in the following cell:
