What is the function of the golgi complex? |
Packages proteins. |
What is the function of the cytoplasm? |
All living material outside of the nucleus. |
What is the function of a the cell membrane? |
Controls movement into and out of the cell. |
What is the function of a lysosome? |
Removes waste from the cell. |
What is the function of a vacuole? |
Stores waste and other raw materials. |
What is the function of the mitochondria? |
Provides energy to the cell and the location for cellular respiration. |
What is the function of a chloroplast? |
The location of photosynthesis in a plant cell. |
What is the function of a cell wall? |
Provides support and protection to plant cells. |
What is the primary shape of a plant cell and how does this compare to an animal cell? |
Plants are rectangular while animals are circular. |
What process can plant cells do that animal cells cannot? |
Plants can perform photosynthesis while animals cannot. |
Which organelle do plants have only a large one vs. animals have many small ones? |
Vacuole |
What provides plants support and protection but is missing in animal cells? |
a cell wall. |
What is a eukaryotic cell? |
a cell with a nucleus such as plant and animal cells. |
What is a prokaryotic cell? |
cells without nucleus such as bacteria. |
What does the cell theory say about where cells come from? |
Cells come from other cells. |
What does the cell theory say is the basic unit of life? |
the cell |
What is the smallest number of cells needed for an organism to be alive? |
one |
Define diffusion |
The movement of particles from high concentration to low concentration |
Define osmosis |
A special case of diffusion involving water |
Define semi-permeable |
A membrane that allows somethings to go through but stops other things |
What are the 3 rules of diffusion |
concentration must be balanced; movement is from high to low concentration; particles must fit through an opening. |
What is the formula for finding the volume of a regular solid? |
length x width x height. |
How do you calculate the density of a material? |
Density = mass / volume |
When two materials are added together how can you tell which will float and which will sink? |
The higher density material will sink. |
What is matter? |
Matter is anything that contains both mass and volume |
What are the three phases of matter |
solid, liquid, and gas |
Define Solid |
state of matter with a fixed volume and shape. |
Define Liquid |
state of matter with a defined volume but will take the shape of its container. |
Define Gas |
state of matter with no fixed volume or shape. |
What do Solid molecules look like? |
Tightly packed molecules with slight vibrations. |
What do Liquid molecules look like? |
Loosely packed molecules and able to slide over one another. |
What do Gas molecules look like? |
Molecules are far apart with little attraction to each other. |
Define Evaporation |
Phase change from a liquid to a gas. |
Define Condensation |
Phase change from a gas to a liquid. |
Define Melting |
Phase change from a solid to a liquid. |
Define Freezing |
Phase change from a liquid to a solid. |
Define Exothermic |
Releases heat during a phase change. |
Define Endothermic |
Gains heat during a phase change. |
Define Heat |
The vibration of particles |
Idenfity a Similarity between heat and temperature |
They are both vibrations of particles |
Idenfity a Difference between heat and temperature |
Temperature can stop changing while heat is always changing. |
define Molecules |
2 or more atoms that are together |
define Atoms |
single elements. |
What are the 3 state/phase of matter? |
solid, liquid, and gas |
define Density |
mass divided by volume; example of physical property. |
Define Potential Energy |
stored energy |
Define Kinetic Energy |
energy of motion such as push, pull, twist, turn |
How do you locate areas of high and low kinetic energy? |
the longer something falls the faster it goes leading to higher kinetic energy. |
How do you locate areas of high and low potential energy? |
the higher something is the more potential energy it has. |
What is the Law of Conservation of Energy? |
the total amount of energy in a closed system is conserved |
What are the 5 levels of the organization of life? |
cells -> tissues -> organs -> organ systems -> organisms |
Define speed |
ratio of distance:time. |
How do you calculate speed? |
distance divided by time. |
