Science Cell, Cell divison, mitosis& microscope test
| Question | Answer |
|---|---|
| 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 |
| Fills up cell and contains all organelles. | Cytoplasm |
| 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 |
