Cell Theory,
Pro/Eu Cells
Pro/Eu Cells
What is the first part of the Cell Theory?
All living things are made up of cells.
What is the job of the vacuoles (or vacuole) in a cell?
Storage!
Which organelle controls what goes in and out of the cell?
The cell membrane
Does Passive Transport require energy?
NO!
Does Active Transport require energy?
YES!! (ATP)
What does "unicellular" mean?
An organism made up of one cell.
Which organelle contains genetic material (DNA)?
The nucleus.
Which organelle protects and maintains the shape of the ONLY plant cells?
Cell Wall
What are the three types of passive transport?
Simple Diffusion, Facilitated Diffusion, and Osmosis.
What's an example of Active Transport?
Sodium-Potassium Pump
What is the third part of the cell theory?
All cells come from pre-existing cells.
Where does cellular respiration happen?
The mitochondria (the powerhouse of the cell)
Give me one orgnelle that can be found in a plant cell but NOT an animal cell.
- Chloroplasts
- Central Vacuole
Which way do the molecules move?
From high to low concentration.
Which way do the molecules move?
From low to high concentration.
What are the two types of Eukaryotic Cells?
Plant and Animal
Which organelle has this job: where proteins are assembled, makes (synthesizes) proteins in a process called translation."
The Ribosomes
Modifies, sorts, and packages materials to be sorted or secreted out of the cell.
Water!
What does "Pinocytosis" mean?
Is the cell drinking.
Give one example of a difference between plant and animal cells.
- Plant cells are more square, animal cells are more round.
- Plant cells use chloroplasts to get their energy, and animal cells have mitochondria to get energy.
- Plant cells have a cell wall; animal cells do not.
- Plant cells use photosynthesis to get energy, whereas animal cells use cellular respiration.
In a Prokaryotic Cell, where is the DNA found?
The Nucleoid.
What's the difference between the rough ER and the smooth ER?
The rough ER has ribosomes, the smooth does not.
Draw examples of each Tonicity level.
Hint: Hypertonic, Hypotonic, Isotonic
Hypertonic: Cell shrivels
Hypotonic: Cell swells
Isotonic: Cell stays the same
What does exocytosis mean?
Process of bringing large particles/materials out of the cell using vesicles. (exo = exit)
