| During interphase, most cells go through three stages-rapid growth and ____________ of the organelles; replication of ______________, the genetic information in a cell; and preparation for ________________. | replication(1) DNA(2) cell division(3)
🗑
|
||||
| During the mitotic phase, a cell ____________ . | divides
🗑
|
||||
| __________makes most of the cell cycle. | Interphase
🗑

||||
| During interphase, the DNA in the cell is called __________. | chromatin
🗑
|
||||
| Interphase begins with a period of rapid growth-the _______ stage. | G1
🗑
|
||||
| During the _______ stage of interphase, the cell replicates its strands of chromatin. | S
🗑

| _______________________ are the two identical strands of DNA that make up the duplicated chromosome. | Sister chromatids
🗑
|
||||
| Sister chromatids are held together by a structure called the ___________________. | centromere
🗑
|
||||
| The final stage of interphase-the ______ stage-is a period of growth and final preparation for the mitotic phase. | G2
🗑

🗑
|
||||
| During ___________, the chromosomes line up in the middle of the cell. | metaphase
🗑
|
||||
| During ____________, sister chromatids in each duplicated chromosome separate and are pulled in opposite directions by the spindle fibers. | anaphase
🗑
|
||||
| During ____________, chromosomes begin to uncoil, and two new identical nuclei form. | telophase
🗑
|
||||
| After mitosis, cytokinesis usually divides a cell’s cytoplasm, forming a new cell ________________ around each daughter cell. | membrane
🗑

🗑

||||
| In plant cells, a(n) _______________ grows outward toward a new cell wall until two new cells form. | cell plate
🗑

| The cell cycle results in two new ________ that are genetically identical to each other and to the original cell, which no longer exists. | cells
🗑

||||
| The cell cycle is important for reproduction in some organisms, growth ______________organisms, replacement of worn-out or damaged cells, and repair of damaged tissues. | multicellular

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
