Microscope
What is a diaphragm?
The diaphragm controls the amount of light that shines up to the slide.
All living things are what?
Organised
What is the function of the cell membrane?
Controls what goes in and out of the cell
What are some examples of carbohydrates?
Bread, vegetables, and pasta.
What does the cell membrane depend on?
Size, Pathway, and whether or not energy is required.
Which two brothers created the first compound microscope?
Hans and Zacharias Janssen
What is the smallest unit of organization of a living thing?
A cell
I transport materials from one side of the cell to the other who am I?
Endoplasmic reticulum.
C,H,O,N,P
What is ATP?
Energy used during active transport.
To calculate the total magnification what do you do?
You times the ocular lens by the objective lenses.
What is the most obvious characteristic of life?
Reproduction the production of offspring
How are animal cells and plant cells different?
A plant cell is square and an animal cell is a circle.
I am the building block of the cell membrane who am I?
Lipids
What is the difference between passive and active transport?
Passive is when energy is not needed and active is when energy is needed.
When focusing the microscope you always start by using what?
Scanning/ low power
What is the difference between growth and development?
growth is the addition of cells while development are the changes that occur over a lifespan.
Why do plants need both chloroplasts and mitochondria?
Because they needed both energy from the mitochondria and the sugar from the chloroplasts and the mitochondria breaks down the sugar to provide the energy.
Organic compounds are made of molecules that contain?
Carbon and hydrogen.
What is the passive transport and what are the three examples of it?
When energy is not needed for molecules to be transported for example diffusion, osmosis, and facilitated diffusion.
Compound microscopes use light with electron microscopes use what?
Beams to magnify an image of a specimen.
What does energy provide?
It provides organisms with the ability to maintain balance, grow, reproduce, and carry out other life functions.
What is the difference between rough endoplasmic reticulum and smooth?
Rough ER has tiny dots on it and makes protein while smooth ER has no dots and makes fat.
What do carbohydrates do?
They supply the energy needed for the cell processes.
What is the concentration gradient?
Differences in concentration between two areas.
