Question 1 of 10
1. Question
The cell theory was proposed to explain the observation that all organisms are composed of cells. Which among the following statements is not a component of the Cell Theory?
Correct
Mitochondria is an organelle to produce energy for the cell, and it is only found in Eukaryote, Thus, not all living things have mitochondria.
Incorrect
Mitochondria is an organelle to produce energy for the cell, and it is only found in Eukaryote, Thus, not all living things have mitochondria.

2. Question
Eukaryotic cells have these membrane-bound structures that contain hydrolytic enzymes which are responsible for breaking down different substrates from endocytosis and cellular waste products. What cellular organelle is being described in the statement?
Correct
Endosomes transport materials to different parts of the cell. The endoplasmic reticulum is a series of interconnected membranes that reaches up to the nuclear envelope. Golgi Apparatus is a stack of membrane-bound sacs.

Question 3 of 10
3. Question
Most cells are relatively small for reasons related to different things. If the microfilaments act as a protection of the cell, which is responsible for the cell-adhesion or the maintenance of the cytoskeleton?
Correct
Intermediate filaments have a resistance to a tremendous amount of tension which increases the structural rigidity of the cell.
Incorrect
Intermediate filaments have a resistance to a tremendous amount of tension which increases the structural rigidity of the cell.

Question 4 of 10
4. Question
Prokaryotes are the simplest organism. Which organelle of prokaryotic cell has the ability to move toward food or away from toxins.
Correct
Flagella have long, whiplike structures used to drive itself forward or away from different substances.
Incorrect
Flagella have long, whiplike structures used to drive itself forward or away from different substances.

Question 5 of 10
5. Question
Since prokaryotes didn’t have multicellular organisms, it is responsible for protecting itself from the environment. Which of the following best describes the outer barrier of the cell and the inner layer that keeps the toxic substance out of the cell?
Correct
The outer barrier is called the cell wall, and the inner layer is called the cell membrane together they are called envelopes.
Incorrect
The outer barrier is called the cell wall, and the inner layer is called the cell membrane together they are called envelopes.

Question 6 of 10
6. Question
Prokaryotes are very important in the ecology of living organism.How do prokaryotes reproduce?
ConjugationCorrect
Binary fission is an asexual reproduction in which the chromosomes are attached to the cell wall, replicates while growing.
Incorrect
Binary fission is an asexual reproduction in which the chromosomes are attached to the cell wall, replicates while growing.

Question 7 of 10
7. Question
All prokaryotic cells contain organelles like ribosomes. What happens to an F+ cell during conjugation?
Correct
When F+ inserts itself from the genome, it becomes a part of the processes involved in transposons.
Incorrect
When F+ inserts itself from the genome, it becomes a part of the processes involved in transposons.

Question 8 of 10
8. Question
All organisms are single cells or aggregates of cell. What part of recombination process joins a foreign genetic material into the host genome?
Correct
Genetic recombination lets the foreign genetic material spill their contents into the vicinity of the bacterium carrying out the process called transformation.
Incorrect
Genetic recombination lets the foreign genetic material spill their contents into the vicinity of the bacterium carrying out the process called transformation.

Question 9 of 10
9. Question
Bacteria uses different forms and pattern during reproduction. When bacteria is being reproduced, what phase of the bacterial growth curve lets the bacteria adapt to its new local conditions?
Correct
The lag phase is the first phase where it allows the bacteria to be familiarized with their conditions.
Incorrect
The lag phase is the first phase where it allows the bacteria to be familiarized with their conditions.

Question 10 of 10
10. Question
The nucleus contains most of the genetic material of the cell. What genetic material is encoded in the nucleus and later is organized into chromosomes?
Correct
DNA is found in the cell nucleus. This is where genetic material is found and is vital during cell division.
Incorrect
DNA is found in the cell nucleus. This is where genetic material is found and is vital during cell division.
