Plant vs. Animal Cells
Which organelle specific to plant cells protects and provides structure and support to the cell?
Cell wall
During the disease outbreak lab, what event got us sick?
Swimming at Old Orchard
This is the control center for the cell, it contains the DNA
Nucleus
Which scientist named the cell while looking at cork under the microscope?
Robert Hooke
What are the two major types of cell transport (think broad terms, not specific methods)
Active and Passive Transport
Which organelle takes in light energy to produce glucose for the cell?
Chloroplast
In the bubble lab, what did the loop of thread represent?
a protein channel
Which organelle provides energy to the cell?
Mitochondria
What scientist found that all animals are made of cells?
Theodor Schwann
What is the major difference between active and passive transport?
Active transport requires energy (ATP) this is because particles are moving against the gradient (low to high)
Passive transport relies on the gradient for movement of particles, it does not need energy.
What is the difference between the vacuoles found in plant cells and those found in animal cells?
Plant cells have one large vacuole, while animal cells have many smaller ones.
In the osmosis lab, why did the potatoes soaked in the salt water lose mass?
The water moved from inside of the potato, to the outside. Causing it to shrink.
Which organelle controls what goes in and out of the cell?
Cell membrane
What did Anton Leeuwenhoek contribute to the cell theory?
He discovered bacteria and other microbes while looking at pond water and dental scrapings under the microscope.
This is the movement of substances out of the cell through vesicles.
Exocytosis
When looking at plant and animal cells under the microscope, what did you notice about the organization of plant cells?
They are more in order, compact, rigid
During the bubble lab, what did we use to represent gap junctions in the cell?
The straw tunnel
Which organelle cleans up waste and old cell parts?
Lysosome
What did Rudolf Virchow contribute to the cell theory?
What is special about facilitated diffusion?
It uses protein channels to guide larger molecules with the gradient, this does not need energy
Choose an organelle only a plant has, then explain why this is specific to plants.
Chloroplasts: plants have to make their own food.
Cell Wall: they need to be able to stand, remain in place
In the osmosis potato lab, which two types of solutions did you make?
1 hypotonic and 2 hypertonic
Which organelle creates proteins?
Ribosome
What are the three parts of the cell theory?
1. all living things are made of cells
2. cells are the basic unit of all life
3. cells come from pre existing cells
What is homeostasis? How does the cell membrane help maintain this within the cell?
Homeostasis is a constant stable physical and chemical state within a cell. The cell membrane is able to regulate what goes into and out of the cell.
