|---|---|---|---|---|---|
| List the stages of mitosis in order: | prophase, metaphase, anaphase, telophase
🗑
|
||||
| How many daughter cells are produced from one cell after mitosis? | 2
🗑
|
||||
| Which phases of the cell cycle are represented by growth, carrying out cell function and preparing for the cell to divide. | G1 - phase where the cell grows and carries out its function
G2 - phase where the cell prepares to divide
🗑
|
||||
| What happens during the S phase of interphase? | DNA copies as the cell prepares to divide
🗑
|
||||
| If there are 46 chromosomes in a human skin cell, how many chromosomes are in a human sperm cell? | 23
🗑
|
||||
| When a chromosome copies itself, it is held together by a.....? | centromere
🗑
|
||||
| The two identical chromosomes held together by the centromere are called sister ______? | chromatids
🗑
|
||||
| In this stage of mitosis, the chromosomes line up in the middle of the cell. | metaphase
🗑
|
||||
| In this stage of mitosis, the sister chromatids can be seen and a spindle begins to form. | prophase
🗑
|
||||
| In this stage of cell division, the cytoplasm divides | cytokinesis
🗑
|
||||
| In this stage of mitosis, the sister chromatids begin to separate and move to opposite ends of the cell | anaphase
🗑
|
||||
| The period where the cell grows, copies its DNA, makes proteins | interphase
🗑
|
||||
| A highly regulated system of signals that controls normal cell divison | cell cycle
🗑
|
||||
| The X and Y chromosomes are called _____ chromosomes | sex
🗑
|
||||
| Gametes (sperm and egg) that have half the number of chromosomes are called ______________ | haploid
🗑
|
||||
| Before a cell can divide, what must happen to the DNA | must be copied (during the S phase of interphase)
🗑
|
||||
| Somatic cells (body cells) undergo ___________ (type of cell division) | mitosis
🗑
|
||||
| Sex cells (gametes) undergo _____________ (type of cell division) | meiosis
🗑
|
||||
| The longest phase of the cell cycle is | interphase
🗑
|
||||
| Why do cells need to undergo cell division? | So organisms can grow, and repair tissue
🗑
|
||||
| If a somatic cell has 20 chromosomes and undergoes cell division (mitosis), how many chromosomes will each new cell have after cell division | 20 because mitosis gives us identical daughter cells
🗑

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.
