Organelles
This exists in both plant and animal cells where organelles float amongst this and it holds everything together.
Cytoplasm
This helps to illuminate the specimen in the microscope.
Light source
Which process involves transport of water particles?
Osmosis
Osmosis is the movement of which type of particles?
Water particles
When using the microscope, you should start at which magnification?
4X
This is only found in a plant cell. This provides added stability for the cell and acts as a "double layer" of protection.
Cell Wall
This acts as a higher powered microscope which allows you to see more then our classroom microscopes.
Electron Scanning Microscope
Which process is sometimes referred to as 'cell eating'?
Endocytosis
Explain what an area of high concentration means.
Lots of particles together.
What does the Diaphragm do?
Controls the amount of light let through from the light source to help view the specimen
This is found in both animal and plant cells - often they are large and fluid filled.
Vacuoles
This cell type is responsible for photosynthesis.
Plant Cell
What process did the tea bag lab show?
Diffusion
How does temperature affect diffusion?
Hot temperatures make particles move faster, therefore diffusion happens faster!
How should you carry the microscope?
Ths exists in both cells. Used to transport materials into and out of the cell and for stability.
Cell Membrane
This technique is used for scientific drawings when we want to discuss shading of a specimen.
Stippling
In diffusion, particles move down a _____________________________.
Concentration Gradient
Particles want balace and equilibrium. They stop moving when this is achieved.
What do the stage clips do?
Hold the slide in place.
This is the 'brain' of the cell responsible for all decision making.
The nucleus
List the 5 characteristics of living things.
Grow, Change, Lifespan, Energy, Produce Waste
Name an example of actual cell transport in our bodies every day?
varies (Oxygen exchange; Insulin; Sugar; Salt)
What was the difference when using a salt water solution for the gummy bear lab? Did it make a big difference then just tap water?
varies. solute concentration.... depends
Give 3 pointers when completing a scientific drawing.
Straight lines, neat printing, stippling for shading, using a ruler to draw label lines, etc.
