Presentation Transcript

  1. Give 4 reasons why cells divide. L X W X 6 = know units L X W X H = know units What measurement determines the rate at which materials enter and leave a cell? What measurement determines how much a cell needs the materials (metabolic rate)?

  2. As a cell grows, the ratio of surface area to volume ________________. Larger cells have (more or less) trouble getting needed nutrients.

  3. asexual reproduction sexual reproduction # parents, type of offspring, speed, type of environment suited for, energy requirements, examples

  4. Which has more DNA, prokaryotes or eukaryotes? What must happen to the genetic material prior to cell division? Why?

  5. 12 chromosomes - mitosis = # cells, # chromosomes 12 chromosomes - meiosis = # cells, # chromosomes haploid vs. diploid genetically diverse cells vs. genetically identical cells somatic cells vs. sex cells (gametes)

  6. Why does a cell spend so much time in interphase? What important process happens in interphase? Why is it necessary?

  7. 2 differences between plant and animal mitosis?

  8. Longest part of cycle? Longest part of mitosis? Opposites? Chemicals that control the cell cycle? Uncontrolled cell cycle?

  9. 2 reasons this process is important?

  10. biopsy carcinogen benign malignant neoplasm metastasis p53 chemotherapy radiation

  11. side effects? why?

  12. totipotent pluripotent multi-potent adult embryonic What is bone marrow? What are some human cells that don’t divide? Why not? How does this affect our health?
