Gen Bio 1 - 1st periodical.pptx for the topic of cell cycle and cell transport

sharing is caring

1. It is the sequence of events from time a cell first arises as a result of cell division until the time when that cell itself divides. Cell Cycle Cell division

2. It is process by which a cell divides to form two new cells. Cell Cycle Cell division

3. Why do cell divides? For growth, development and reproduction. For growth, development and continence

4. It is the resting stage in a cell cycle. Interphase Prophase

5. The protein that activates the checkpoints in interphase. Kinase Enzyme

6. In this phase, the cell increases in size and takes up about 41% of the cell’s life cycle. G(1) Synthesis

7. In this phase, the cell forming double organelles, cytoplasm and all other structure need for mitosis G(1) G(2)

8. In this phase, the cell is taking up approximately 20% of the cell cycle and allows the DNA replication of the cell. G(1) Synthesis

9. It is the division of reproductive cells. Mitosis Meiosis

10. It is the division of body cells. pertaining to epithelial, bone, blood, and muscle cells and etc. Mitosis Meiosis

11. A part of a chromosome where the two chromatids are held together. Centromere Chromatin

12. It is an individual's complete set of chromosomes. Karyotype Genetics

13. Longest stage of mitosis that Taking up about half of the time of the entire mitotic cycle. Prophase Metaphase

14. Shortest stage of mitosis that the c hromosomes become more conspicuous, emerging to be dark and thick elongated boudes connected to the spindle fibers. Prophase Metaphase

15. What stage of mitosis that the s pindle fiber begins to form Prophase Anaphase

16. In the metaphase stage, the chromosomes move towards the cell’s equatorial plate known as? Metaphase plate Metaphase sheet

17. It is the stage of mitosis, where the chromatids are being pulled to opposite sides of the cell. Prometaphase Anaphase

18. It is the stage of mitosis, where the chromosomes assemble sets and uncoil. Telophase Anaphase

19. It is the stage of mitosis, where it completes the disintegration of the cleavage furrow. Karyokinesis Cytokinesis

20. It is the division of gametes (reproductive cells) specifically the female egg and male sperm. Meiosis Mitosis

21. What stage in meiosis division does the chromosome of the father’s genome pair up with the chromosome carrying the mother's genome? Prophase I Metaphase I

22. What do you call the pairing of two chromosomes that occurs during meiosis? Synapsis Zygote

23. What stage in meiosis division, is marked by the lining up of the homologous chromosomes in the said plate? Prophase I Metaphase I

24. What stage in meiosis division, m arked by the pulling apart of the homologous chromosome by the spindle fibers. ? Anaphase I Telophase I

25. What stage in meiosis division, that the complete set of chromosomes has fully migrated to the opposite poles? Anaphase I Telophase I

26. What division in meiosis , the number of chromosomes is reduced into half so that each of the daughter cells reaches haploid? Meiosis I Meiosis II

27. What division in meiosis , the number of chromosomes is reduced into half so that each of the daughter cells reaches haploid? Meiosis I Meiosis II

28. It is the production of gametes or the gamete formation from haploid precursor cells. Gametogenesis Oogenesis

29. It is the production of gametes of female gametogenesis. Gametogenesis Oogenesis

30. It is the production of gametes of male gametogenesis. spermatogenesis Oogenesis

31. It is abnormal mass of tissue that forms when cells grow and divide more than they should Tumor Lymph

32. A cancer cell may depart from its original location and travel to the different body parts through the bloodstream. Metastasis apoptosis

33. This process of “self-destruction” or programmed cell death. Metastasis apoptosis

34. These are capable of altering the DNA sequence which lead to damaging the cell structure Carcinogens Coarse chromatin

35. What do you call the fertilized egg? Zygote Ovum

36. It is the “ g atekeeper” of the cell—regulates flow of materials into and out of cell Cellular membrane Nucleus

37. The cell membrane is responsible for maintaining “a stable, internal environment” or what we called? Homeostasis Equilibrium

38. C ell membrane are made up of these materials: Phosphate, protein and lipids Ribose, lipids and phosphate

39.   A surface of a cell that has the ability to repel water. Hydrophilic Hydrophobic

40. It is the movement of water through a “selectively permeable” membrane like the cell membrane. Diffusion Osmosis

41. A process in cell transport that mostly does not require energy to move molecules from HIGH to LOW concentration. Passive transport Active transport

42. It is movement of small molecules/ions across the cell membrane. Diffusion Osmosis

43. One type of osmosis concentrations where the cells shrinks and wrinkles. Hypertonic Hypotonic

44. One type of osmosis concentrations where the cells swell up and burst. Cytolysis Plasmolysis

45. One type of osmosis concentration where the cells act normal. Hypertonic Isotonic

46. Facilitated transport makes use of these special proteins that enable huge and charged particles to enter the cell membrane. Carrier protein integral membrane proteins.

47. T he movement of particles opposite the concentration gradient and it requires the use of chemical energy. Active transport Passive transport

48. It a mode of transport of large quantities of materials and food particles across the membrane Bulk transport Macro transport

49. It is a cellular process in which substances are brought into the cell. Pinocytosis Endocytosis
