Cells #1 -- Genoa

Microscopes, CLT, Cell History & Cell Theory

QuestionAnswer
organism an individual living thing
energy power from physical/chemical resources
wastes products of chemical reactions; must be eliminated from a cell
adapt a genetic variation that helps an organism survive in a changing environment
cell the basic/smallest unit of structure, function and organization in an organism (The second part of the "Cell Theory".)
unicellular a one/single celled organism
multicellular an organism made of many cells
stimulus a change in an organism's surroundings that cause it to react
response an action or change in behavior that occurs as a result of a stimulus
growth the process of becoming larger; the addition of mass (cells) to an organism
development the natural changes that take place during an organism's life-cycle which produce a more complex organism
reproduce to produce offspring that are similar to the parent(s); to make more of the same kind of organism
scientific theory an explanation of the natural world that is confirmed/proven with the scientific method--> observation & experimentation
cells All living things are made of one or more _____. (The first part of the "Cell Theory".)
six How many CLT are there? _____
three How many parts/statements are there in the "Cell Theory"? _____
seven In class, we listed how many "Cell History" scientists? _____
two In class, we have compound microscopes which means they are made with _____ convex lenses.
fine Because the objects we view under a microscope are 3-D, we must focus back and forth with the _____ focus knob while viewing on medium and high powers.
upside As a result of a compound microscope using two convex lenses, the image we see is _____ down.
forty If the eyepiece lens is 10x and the low power lens is 4x, the total magnification is _____x. (HINT: multiply the two numbers)
Schleiden Name the German scientist who studied/concluded that all plants are made of cells.
Schwann Name the German scientist who studied/concluded that all animals are made of cells.
The third part of the "Cell Theory" ALL cells come from existing cells.
Hooke While looking through a microscope, this English scientist saw "little rooms" (boxes) when looking at cork and was the first person to call them CELLS.
Leeuwenhoek This Dutch scientist built high-quality lenses/microscopes and was the first person to see living cells (protists, bacteria, red blood cells, etc.).
hundred If the eyepiece lens is 10x and the medium power lens is 10x, the total magnification is one _____x. (HINT: multiply the two numbers)
four If the eyepiece lens is 10x and the high power lens is 40x, the total magnification is ____ hundred x. (HINT: multiply the two numbers)
