|---|---|---|---|---|---|
| occurs in a series of stages, or phases | Cell division
🗑
|
||||
| chromosomes are copied(# doubles) chromosomes apper as threadlike coils (chromatin)at the start, but each chrtomosomee and its copy change to sister chromatids at the end of this phase | Interphase
🗑
|
||||
| mitosis begins (cell begins to divide) centrioles (or poles) apper and begin to move to opposite ends of cell spindal fibers form between the poles | Prophase
🗑
|
||||
| chromatids (or pairs of chromosomes) attach to the spindal fibers | Metaphase
🗑
|
||||
| chromatids (or pairs of chromosomes) seperate and begin to move to opposite ends of the cell. | Anaphase
🗑
|
||||
| two new nuclei form chromosomes appear as chromatin(threads rather than rods) mitosis end | Telophase
🗑
|
||||
| cell membrane moves inward to create two daughter cells-each with its own nucleus with identical chromosomes | Cytokinesis
🗑
|
||||
| protects and supports cell | Cell wall
🗑
|
||||
| protection; controls what enters and leaves cell | Cell membrane
🗑
|

| Stores materials | Vacuole
🗑
|

| Transport system for the cell | Endoplasmic Reticulum
🗑
|
||||
| Produces protiens | Ribosome
🗑
|
||||
| Packages and prepairs materials to be shipped out of cell | Golgi body
🗑
|
||||
| produces energy for the cell | Mitochondria
🗑
|
||||
| Allows substance to enter and leave nucleus | Nuclear Membrane
🗑
|
||||
| Directs all cell activities | Nucleus
🗑
|
||||
| Produces Ribosomes | Nucleolus
🗑
|
||||
| contains instructions for traits and physical characteristics | Chromosome
🗑
|
||||
| Contains Chlorophyll: site of photosynthesis | Chlorophyll
🗑
|
||||
| Helps the cell during cell division | Centriole
🗑
|
||||
| Cellular digestion; breaks down proetiens,fats and carbohydrates | Lysosome
🗑
|
||||
| Centriole/ Centrosome | The organelles only found in plant cells
🗑
|
||||
| Lysosome | The organelles only found in animal cells
🗑
|
||||
| In plant cell it has Chloroplats, and in animal cell it has Lysosome | The difference between animal and plant cell is:
🗑
|
||||
| contains the ocular lens | Eyepiece
🗑
|
||||
| connects the eyepiece to the nosepiece | Body Tube
🗑
|
||||
| Hold the low and high power objective lenses can be rotated to change magnification. | Nosepiece
🗑
|
||||
| Magnification ranges from 4x to 40x. | Objective lenses
🗑
|
||||
| Moves the stage up and down for focusing | Coarse adjustment knob
🗑
|
||||
| Moves the stage slightly to sharpen the image | Fine adjustment knob
🗑
|
||||
| Used to support the microscope when carried | Arm
🗑
|
||||
| Supports the slides being viewed | Stage
🗑
|
||||
| Holds the slide in place | Stage Clips
🗑
|
||||
| Regulates the amount of light on the specimen | Diaphragm
🗑
|
||||
| Projects light upward through the diaphragm and the eyepiece | Light source
🗑
|
||||
| Supports the microscope | Base
🗑

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.
