6. During photosynthesis, carbon dioxide enters the plant through small openings in the leaf, which in turn, is also where oxygen escapes as a by-product of the food-manufacturing process. What do we call this structure in the leaves of plants?

7. Light-dependent reaction in photosynthesis requires light energy to break down water molecules into ATP, NADPH, and oxygen. This chemical reaction takes place in which of the following structure of chloroplast?

8. Which of the following best describes zoonotic viruses like the COVID-19-causing virus?

9. Helper T cells are essential in the body's immune response. When attacked, their number decrease resulting to a declined function in fighting off diseases and infection. Which of the following human viruses can do the abovementioned function to the human body?

10. Proteins are sorted, processed, and delivered in which of the following membrane-bound cell organelles?

11. Which of the following is/are the function/s of connective tissues?

I.          They serve as a binding substance.

II.        They cover the surface of the body and lines body cavities.

III.     They provide the framework that support epithelial and other tissues.

IV.     They are responsible for the protection, secretion, and absorption of materials.

12. What is the function of the microscope part being pointed by the arrow from the image below?

13. Mitosis replicates chromosomes which are contained in cells that arose from cell division. Which proposition of the Modern Cell Theory is being exemplified?

14. Jhon Aaron is viewing a sample slide through a compound microscope using the high-power objective lens. The specimen was magnified at 2000x. What is the original size of the specimen?

15. Paul was using a compound microscope to view cheek cells. The slide was stained with methylene blue to emphasize the structure of the specimen. However, the stain makes the view of the specimen dim. What must Paul do?

16. Which of the following exemplifies that cell arise from pre-existing cells?

17. Peter was examining a slide under a microscope. However, he couldn’t have a nice view of the specimen because of his height; so, he needs to tilt the microscope lower enough for him to view. Which part of the microscope must he adjust?

18. Jasper wanted to view a sample slide under a compound microscope. The specimen size is 2 microns, and he wants to magnify it 2000x. What objective lens must he use to achieve the magnification?

19. Foreign objects, like bacteria, enters the cell but is engulfed by an organelle which contains enzymes; thereby digesting them. Which organelle is responsible for this function?

20. Emerson is viewing a specimen through a compound microscope. He wants to move the objective lens nearer to the specimen he is viewing. Which part of the microscope must he manipulate?

41. Rudolf Virchow proposed that cells arise spontaneously.

42. Regardless of the specimen size, an object will be magnified by a total of 400x using the high-power objective lens.

43. Anton van Leeuwenhoek referred to bacteria and protozoa as animalcules because of their motility.

44. An organ system is a group of systems working together as one functional unit.

45. Cell wall is present in animal cells.

46. Mice arising from sweaty underwear exemplifies the belief on spontaneous generation.

47. The stage clips in microscope hold the stage in place.

48. The ocular lens magnifies the specimen image by 10x.

49. Reproductive organs, such as the testes and ovaries are made up of reproductive cells.

50. Resolution refers to the enlargement of the specimen’s image.

51. Pasteur’s swan neck flask experiment supported that cell arises from pre-existing cells.

58. Jansen was credited for the invention of the first compound microscope.

59. Twenty-five elements from the ninety-two naturally-occurring elements can be found in the human body.

60. Lazzaro Spallanzani supported the spontaneous generation of cells in his experiment.
