Who built the first microscope and why was it so important?
Hooke and because we can't see cells with naked eye

the mitochondria because it produces energy
100
Where are electron microscopes used and why?
in medicine, NASA because it is very advanced

How does an electron microscope work?
the electron beams create the image

What do we call the Golgi Bodies and why? What do they do?
"mail room" because they pack protein from endoplasmic reticulum and send them to other parts of cell

Vacuoles are water filled sacs that store food, material, and waste. What is a waste that is released from the cell, where does it go?
carbon dioxide from cell to bloodstream in lungs and out

What are the 4 needs of living? What are animals that
"make food" and "get food" called? What is having "stable internal conditions" called?
1. water
2. food
3. living space
4. stable internal conditions.
- homeostasis.
- autotrophs (plants) & heterotrophs (animals)
500
What are the properties of protists? give me an example
some autotroph/heterotroph
mostly unicellular, some multicellular
ex) seaweed

What are the 3 things the cell theory states?
1. all living things made of cells
2. cells are basic unit of structure/function
3. cells are produced from other cells
500
What is the order of cell organization (5 steps)
cells --> tissues --> organs --> organ system ---> organism
500
What is Pasteur's experiment like? (give summary)
2 flasks with broth.
One is heated to get rid of bacteria.
Over time, that one NOT heated changes color (because bacteria is present).
When curved neck comes off clean broth, bacteria from air go in and it changes color
