Questions and Answers

1.

What structure do a volvox and a euglena use for movement?
- A.
  
  Cilia
- B.
  
  Pseudopods
- C.
  
  Flagella
- D.
  
  Eyespot
Correct Answer
C. Flagella

Explanation
While the euglena does have an eyespot, it is used to detect light. Amoebas use pseudopods for movement. Cilia are used for movement by paramecium.

- A.
  
  Hotdog
- B.
  
  Cell phone
- C.
  
  Golf ball
- D.
  
  Tree leaf
Correct Answer
C. Golf ball

Explanation
because both the volvox and a golf ball are spherical in shape

A ______________________ is a type of cell that has a true nucleus.
- A.
  
  Prokaryote
- B.
  
  Eukaryote
- C.
  
  Bacterium
- D.
  
  Virus
Correct Answer
B. Eukaryote

Explanation
prokaryotes and bacteria have primitive nuclei and virus are not even living

4.

Two structures found in plant cells that are not found in animal cells are the
- A.
  
  Mitochondria and ribosomes
- B.
  
  Cell wall and plastids
- C.
  
  Cell membrane and centrioles
- D.
  
  Nucleolus and endoplasmic reticulum
Correct Answer
B. Cell wall and plastids

Explanation
all others are found in both.

5.

Somatic cells reproduce using
- A.
  
  Sexual reproduction
- B.
  
  Asexual reproduction
- C.
  
  Gametes
- D.
  
  Mutations
Correct Answer
B. Asexual reproduction

Explanation
somatic cells are your normal body cells they use mitosis and your gametes are your sperm or egg cells and they use meiosis.

6.

The necessary characteristics a substance must have in order to be classified as living are
- A.
  
  A heart and lungs
- B.
  
  The ability to nourish itself, grow, and reproduce
- C.
  
  The ability to photosynthesize and to eliminate waste products
- D.
  
  A true nucleus and nuclear membrane
Correct Answer
B. The ability to nourish itself, grow, and reproduce

Explanation
to be living: have to be made of carbon, have to be able to respire (breathe), to take in nutrients, eliminate wastes, respond to stimuli, grow and reproduce.

7.

Groups of cells that perform the same function are collectively known as
- A.
  
  Plastids
- B.
  
  Tissues
- C.
  
  Organs
- D.
  
  Molecules
Correct Answer
B. Tissues

Explanation
Cells make us tissues, tissues make up organs, organs make up organ systems, organ systems make up organism.

Rate this question:
8.

Amoebas obtain food by wrapping the cell membrane around the food particle, creating a vesicle. The food is then brought into the cell. This process is called
- A.
  
  Exocytosis
- B.
  
  Endocyotosis
- C.
  
  Osmosis
- D.
  
  Photosynethesis
Correct Answer
B. Endocyotosis

Explanation
Photosynthesis is using the sun to make energy. Osmosis is water moving across a cell membrane. Exocyosis is particles leaving a cell using a vesicle. Endocyotosis is particles crossing a cell membrane using a vescile. Remember ENDO looks and sounds like IN.

Rate this question:
9.

Mitosis generates
- A.
  
  Daughter cells identical to the mother cell
- B.
  
  Many reproductive cells
- C.
  
  Diseased cells
- D.
  
  Gametes
Correct Answer
A. Daughter cells identical to the mother cell

Explanation
After mitosis is complete the daughter cells are exact copies of the mother cell. Gametes are sex cells and they are not exactly the same as the mother cell. Mitosis only generates one new daughter cell for every mother cell.

Rate this question:
10.

Meiosis is a type of cell division that
- A.
  
  Leads to genetic mutation
- B.
  
  Creates somatic cells
- C.
  
  Is necessary for sexual reproduction
- D.
  
  Causes alleles to deform
Correct Answer
C. Is necessary for sexual reproduction

Explanation
Meiosis generates the sex cells so it is necessary for sexual reproduction.
