FINAL Flashcards
Controlled experiment
Experiment in which all variables are kept unchanged except one
Manipulated variable
The variable that is changed between the control group and the experimental group
Control group
The group that is being tested under normal conditions
Experimental group
The group that is being tested under the new or experimental conditions
Monomer
Small repeating units that fit together to form polymers
Polymer
Large molecules that are formed by joining together many monomers
What is the total magnification under a microscope?
X10
Unicellular
An organism made up of one cell
Multicellular
An organism made up of many cells
Why do cells need to stay small?
If cells get to big they can’t take in nutrients and let out waste
Eukaryotic
A cell that has a Nucleus
Prokaryotic
A cell that does not have a nucleus
Cell membrane
Controls what enters and leaves the cell
Cytoplasm
Everything between the cell membrane and the nucleus
Nucleus
Control center of the cell
Nucleolus
Produces the ribosomes
Ribosomes
Produces the ribosomes
Golgi body
Notifies and packages proteins to be shipped where they are needed
Endoplasmic reticulum
Produces lipids, proteins and other particles use the ER to move about the cell
Mitochondria
Makes ATP energy through cellular respiration
Cellular respiration equation
02 + CHO»_space; H2O + CO2 + ATP
Chloroplasts
Makes food for the plants
Photosynthesis equation
H2O + CO2 + ATP»_space; O2 + CHO
Lysosomes
Breaks down food, bacteria, waste and worn out cell parts
What do plant cells have that animal cells do not?
Large vacuole, chloroplasts, cell wall
Diffusion
Particles move from an area of high concentration to an area of low concentration
Osmosis
The diffusion of water through a semi-permeable(water moves from high to low concentration of water)
Solute
Substance that dissolves
Solution
Mixture of 2 or more substances in which the molecules of each substance are evenly distributed
Solvent
Substance in which the solute is dissolved
Hypertonic
The one that has a higher concentration of solute
