Bio Unit 1 Flashcards
What’s the difference between monocular and binocular microscopes
Mono use one eye
Bino uses two eyes
How do you find the magnification
Multiply the the object number by the eyepiece
How do you carry the microscope
Carry the Microscope by the base and arm
How do you categorise cells
By the presence and absence of particular organelles
Why are cells small
So they can take in substances quickly and discrete waste
What is in the Cell membranes
Most cells have a cell membrane made of cytosol and ribosome.
What does the cell membranes do
Regulates the movement of substances into and out of the cell.
Why doesn’t Unicellular cells have cell membrane
Because they can carry out the same process without a cell membrane
How do cells reproduce
By splitting into 2
Five kingdoms
Protocitista Animalia Plante Fungi Prokaryotes
What are multicellular made up of
Different cells with different jobs. Those cells have particular structures
Nucleus
Controlling centre of cell
Mitochondria
Energy, power pack, deals with cell respiration
Chloroplast
On,h I’m plants
Uses energy from the sun to make food
Vacuoles
Stores water
Golgi bodies
Packages protein into membrane
Cell wall
Makes the plant cell rigid
Mitochondria and chloroplast are ….
Membrane- bound organelles
Mitochondria is found in …
All cells as they are involved in cellular respiration
What cells are chloroplasts found in
Cells that photosynthesis
How to make a wet mount
- Put a drop of water on a pipette
- Place cover slip over by putting one edge down first
- Use microscope
Microscope
An instrument for viewing small objects
Cells
Smallest unit of life
Building block of living things
Different sizes and shapes
Light microscope
Uses light to magnify things up to 1500 times bigger
