Science Cell, Cell divison, mitosis& microscope test

QuestionAnswer
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
