Cells And Cell Theory Quiz
This quiz will help you to see how much you know about cell theory.
- 1.
According to cell theory, all cells
- A.
Are eukaryotes
- B.
Are prokaryotes
- C.
Have nuclei
- D.
Come from other cells
Correct Answer
D. Come from other cellsExplanation
There are prokaryotic (means does not have a true nucleus) and eukaryotic (means does have a true nucleus) cells. There are some cells do not have a true nucleus. But all cells can only come from other cells.Rate this question:

- 2.
The mitochondrion of a cell
- A.
Has only one membrane
- B.
Has no membrane
- C.
Is circular
- D.
Is where cellular respiration occurs
Correct Answer
D. Is where cellular respiration occursExplanation
The mitochondrion has two membranes and is kidney-bean shaped. It is the site of cellular respiration because it is where sugars are broken down into energy. Cellular respiration is the process where the cell is provided energy.Rate this question:

- 3.
Structures that support and give shape to plant cells are
- A.
Microbodies
- B.
Golgi bodies
- C.
Nucleus
- D.
Cell walls
Correct Answer
D. Cell wallsExplanation
There are no microbodies, Golgi bodies modify and transport proteins, and the nucleus directs the cell by telling it what to do. Cell walls support the plant cell by giving a rigid shape of a rectangle. The cell wall also helps the plant hold on to the water that it has stored.Rate this question:

The storage of hereditary information in a eukaryotic cell is in the
- A.
Cytoplasm
- B.
Nucleus
- C.
Centrioles
- D.
Lysosomes
Correct Answer
B. NucleusExplanation
The nucleus has the DNA (hereditary info), the cytoplasm is the fluid that the organelles of the cell float in, the centrioles aide in mitosis, and the lysosomes break down materials in the cell.Rate this question:

- 5.
In what way are all cells similiar?
- A.
The function in a similiar way
- B.
The have similiar structures
- C.
The make similiar products
- D.
They are used by similiar organisms
Correct Answer
A. The function in a similiar wayExplanation
Plant cells have structures that the animal cell does not, cells don't really create a product, and all living organims have cells. But all cells function in the same way in that they respire, take in nutrients, respond to stimuli, reproduce and so on.Rate this question:

- A.
Organ system
- B.
Organ
- C.
Cell
- D.
Organelle
Correct Answer
A. Organ systemExplanation
The brain and spinal cord are seperate organs but they are working together to perform this job.Rate this question:

- 9.
Which of the following is listed from least to most complex?
- A.
Organ, organism, cells
- B.
Cells, tissues, organism, organ system
- C.
Cells, organ, organism
- D.
Tissues, organism, organ
Correct Answer
C. Cells, organ, organismExplanation

-
- 10.
Which of the following is an example of a tissue?
- A.
Chloroplast
- B.
Stomach
- C.
Human
- D.
Bicep
Correct Answer
D. BicepExplanation
Chloroplast is part of the plant cell, stomach is an organ, human is an organism but bicep is tissue because it is made up of the same type of cells doing the same job.Rate this question:
-
- 11.
What is the movement of substances into and out of a cell without the use of energy called?
- A.
Active transport
- B.
Passive transport
- C.
Exocytosis
- D.
Endocytosis
Correct Answer
B. Passive transportExplanation
Active and passive transport involves materials entering and leaving the cell. But, active requires energy and passive does not. Exocytosis means things leave the cell only. Endocyotosis means things enter the cell only.Rate this question:
-
- 12.
What happens during active transport?
- A.
Water moves passively through a membrane
- B.
The movement of particles occurs spontaneously in the opposite direction of concentration.
- C.
Cells must use stored energy to move substances across a membrane
- D.
Cells allow the spontaneuous movement of particles across the membrane.
Correct Answer
C. Cells must use stored energy to move substances across a membraneExplanation
Since the question asked about active you are looking for an answer the describes using energy. Answers a, b, d all refer to passive transport which does not require energyRate this question:
-
- 13.
The process of releasing energy from the chemical breakdown of compounds in a cell is
- A.
Hesitation
- B.
Expiration
- C.
Elimination
- D.
Respiration
Correct Answer
D. RespirationExplanation
The definition of respiration is breaking down chemcials to provide energy for the cellRate this question:
-
- 14.
What is the result of mitosis?
- A.
2 identical cells with identical amounts of genetic material
- B.
4 cells that have half the genetic material of the parent
- C.
2 cells that have half the genetic material of the parent
- D.
Genetic variation, which is vital to species survival
Correct Answer
A. 2 identical cells with identical amounts of genetic materialExplanation
In mitosis you end up with 2 daughter cells that are exact copies of the parent cell. In mitosis, you end up with 4 daughter cells that have half of the genetic material and this is where you see genetic variation. There is not way to end up with 2 cells with half of the material.Rate this question:

In photosynthesis, plants use carbon dioxide, water and light to produce
- A.
Carbon monoxide
- B.
Energy
- C.
Glucose and oxygen
- D.
Chlorophyll
Correct Answer
C. Glucose and oxygenExplanation
Carbon monoxide is harmful gas that comes out of our car's tail pipe, and chlorophyll is the green pigment that makes plants be green. Glucose and oxygen are produced in photosynthesis so that the glucose can be converted to energy for the cell.Rate this question:

- A.
Quick
- B.
Tumbling
- C.
Twirling
- D.
Oozing
Correct Answer
D. OozingExplanation
Amoebas move slowly using their pseudopods to anchor them and then the ooze their cytoplasm in the direction of the pseudopod to pull them in that direction.Rate this question:

Which structure below helps many protists rid themselves of wastes?
- A.
Oral groove
- B.
Eyespot
- C.
Flagellum
- D.
Lysosome
Correct Answer
D. LysosomeExplanation
Oral groove is for eating, eyespot is for sensing light and flagellum is for movement. Lysosomes break down wastes and other materials in a cell that are unwanted.Rate this question:

Which structure listed below helps the Euglena sense and respond to their environment?
- A.
Contractile vacuole
- B.
Flagellum
- C.
Eyespot
- D.
Chloroplasts
Correct Answer
C. EyespotExplanation
contractile vacuole gets rid of excess water, flagellum is for movements and chloroplasts are site of photosynthesis in plant cells. The eyespot detects light and helps the Euglena to know where to find light so that it can photosynthesize.Rate this question:
