Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

5 notecards = 2 pages (4 cards per page)

Chapter 12 Quiz

front 1

Why do some species employ both mitosis and meiosis, whereas other species use only mitosis?

  • They need meiosis if the cells are producing organs such as ovaries.
  • They need only meiosis if they produce egg cells.
  • They need both if they are producing plant gametes.
  • They need only mitosis to make large numbers of cells such as sperm.

back 1

They need both if they are producing plant gametes.

Ex.

The production of gametes in plants is a function of both mitosis and meiosis. The form of cell division that produces animal gametes is meiosis, not mitosis.

front 2

A human bone marrow cell, in prophase of mitosis, contains 46 chromosomes.

  • True
  • False

back 2

True

front 3

Which of the following is true of kinetochores?

  • They are sites at which microtubules attach to chromosomes.
  • They are located at the center of the centrosome; their function is to organize tubulin into elongated bundles called spindle fibers.
  • They attach to the ring of actin along the cytoplasmic surface of the plasma membrane, causing the actin to contract to form the cleavage furrow.
  • They are the primary centromere structures that maintain the attachment of the sister chromatids prior to mitosis.

They are sites at which microtubules attach to chromosomes.

front 4

G1 follows cell division.

  • True
  • False

back 4

True

front 5

In some organisms, such as certain fungi and algae, cells undergo the cell cycle repeatedly without subsequently undergoing cytokinesis. What would result from this?

  • a decrease in chromosome number
  • division of the organism into many cells, most lacking nuclei
  • a rapid rate of gamete production
  • large cells containing many nuclei

back 5

large cells containing many nuclei
