Bacteria
What is the flagellum used for?
Movement
What does the cell wall do?
Maintains shape and structure; lets some things through
What is the cilia used for?
What is homeostasis and why is it important?
Homeostasis is a cell maintaining internal balance; it's important because being out of homeostasis could damage or kill the cell
What kind of transport requires no energy from the cell?
Passive Transport
What kind of cell are bacteria?
Prokaryotic Cells
What kind of cells are plant cells?
Eukaryotic Cells
What kind of cells are animal cells?
Eukaryotic Cells
What is a colony?
What kind of transport requires energy from the cell?
Active transport
What does the nucleoid do in bacteria?
Contains genetic material
What does the chloroplast do?
Converts light energy into chemical energy (photosynthesis)
What does the nucleus do?
Controls the actions of the cell and contains genetic material
Why does transport in cells happen?
What does the capsule do in bacteria?
What does the rough ER do?
transports things, maintains cell shape, processes proteins
What does the smooth ER do?
Transports things, maintains shape, process fats and breaks down toxic substances
What is positive feedback?
Name one kind of passive transport
Diffusion, osmosis, facilitated diffusion
What is cytoplasm?
The "blood" of the cell; the liquid in which organelles and other things float around in.
What does the central vacuole do?
What does the Golgi Apparatus do?
"post office" of the cell - packages substances into vesicles and sends them around
What is negative feedback?
A substance produced by a cellular process slows or stops the process
What is one factor that determines whether a cell can be passively transported?
Particle size, particle shape, particle polarity, membrane composition
