diamong [38]

Answer:

1. mitochondria  

2. centrioles

3. lysosome

4. cytoplasm (cytosol)

5. nucleolus  

6. nuclear envelope

7. chromosomes

8. cilia

9. Rough endoplasmic reticulum

10. Golgi apparatus  

11. citoesqueleton  

12. vesicles

13. ribosomes

14. smooth endoplasmic reticulum

15. cell membrane  

Explanation:

Mitochondria are the energy centers of the cell that work to produce ATP. Centrioles are organelles composed of tubulin protein that organize microtubules that serve as the cell's skeletal system. Lysosomes are vesicles that contain hydrolytic enzymes. The cytosol is a thick solution inside the cell which is enclosed by the cell membrane. The nucleolus is an organelle inside the cell nucleus involved in the transcription of ribosomal RNAs. The nuclear envelope is a membrane that surrounds the cell nucleus (in eukaryotic organisms). Chromosomes are linear molecules composed of chromatin (DNA + histone proteins) which contain the genetic material of the cells. The cilia are organelles found on eukaryotic cells involved in the movement of the cell. The rough endoplasmic reticulum is an organelle whose function is the processing of proteins synthesized in the ribosomes, while the smooth endoplasmic reticulum functions in lipid synthesis. The Golgi apparatus is an organelle involved in transporting and packaging proteins and lipids. The cytoskeleton is a dynamic network of protein filaments that act as the skeleton of the cells. Vesicles are membrane-bound structures that transport substances in the cell. The cell membrane is a lipid bilayer that acts to transport nutrients into the cell and waste products out of the cell.

Cell division is preceded by two growth phases. Besides growth, both G1 and G2
Leviafan [203]

Answer:

A

Explanation:

a. contain checkpoints that determine if the cycle will continue.

b. help move chromosomes to the new daughter cells.

c. produce more chromosomes before the cell divides.

d. grow and produce enough cytoplasm to fill two cells.

<em />

<em>The correct answer would be that G1 and G2 contain checkpoints that determine if the cycle will continue or otherwise.</em>

The cell cycle generally has three checkpoints that happen at G1, G2, and M phase of the cycle.

At G1 checkpoint, the integrity of the DNA of the cell is assessed to ensure that there are no damages and other conditions such as size and energy reserve are checked.

At G2 checkpoint, the cell is assessed for proper chromosome duplication to ensure that there are no mistakes or damages. The size of the cell and the amount of protein are also checked to ensure that the cell is ready for the active division phase.

At M checkpoint, correct attachment of the spindle fiber to the kinetochore of the chromosomes is checked. This checkpoint is also known as the spindle checkpoint and it happens towards the concluding phase of the metaphase stage.

<u>The correct option is therefore, A.</u>
