How to carry a microscope

By the arm and base

Eyepice

The part you look through

I know the three parts of cell theory (think of the song)

all living things are made up of cells cells are the basic unit of structure and function also has come from pre-existing cells

what did hooke and leeuwenhoek do

discovered the microscope

what objective lens do you use coarse fine knob

high power

arm

hold on to when carrying the microscope supports the stage and upper part of microscope

stage clips

holds the specimen in place

what objective lens do you use coarse adjustment knob

low and medium power

fine adjustment knob

moves the stage slightly to sharpen the image only used in high power

coarse adjustment knob

moves the stage up and down only used with low and medium power

light source

project light upwards through the diaphragm the specimen and the lenses

Lysosomes

recycles waste

Diaphragm

rotating Circle under the stage that changes the brightness you see through the lenses

stage

supports the specimen being viewed moves up and down to zoom in

Golgi body

the structure packages and moves proteins through the cell

mitochondria

the structures are known as the PowerHouse of the cell because they release and produce energy

ER

there are two types of this structure a smooth and a rough one produces energy for the rest of the cells to function

ribosomes

these organelles build or synthesize proteins for the cell

Chloroplast

this is a green structure is only found in plant cells and uses energy from the Sun to make food

vacuole

this is a large fact that holds food water and waste

cell membrane

this is an outer layer of an animal cell and it controls movement in and out of the cell

Nucleus

this is the brain of the cell and it controls the cell's activities

Cytoplasm

this is the jelly like substance that holds and protects the organelles

cell wall

this outer layer of the plants out supports the cell

objective lens

three objectives lens for times 10 times 40 times magnification
