Organelles
These are like small organs in the cell that have specific jobs
What are organelles
What is the function of the cell membrane
Allows molecules to enter and leave the cell
What is the function of the chloroplast?
Where photosynthesis takes place
Membrane transport that does not require energy or a protein channel/carrier?
Passive transport
The sodium-potassium pump is a form of active transport, why is energy needed for active transport.
Energy is required to move ions from an area of low concentration to high concentration.
Protects and supports a plant cell
What is cell wall
Name two structural components of the cell membrane
phospholipids/protein channels/cholesterol
What is the function of the lysosomes
Contains digestive enzymes to dispose of unwanted cell material
Substance being dissolved
solute
Have equal amounts of solute inside and outside the cell
isotonic solutions
This organelle is the storage area in the cell
What is vacuole
Describe the small structure that makes up the bilayer of the cell membrane?
phospholipids with polar head and non-polar tail
What is the function of the nucleus?
Contains the cells DNA and control the cell functions
I have old cellular material that needs to be recycled. Which organelle will break down food and old cell parts?
Lysosomes
_____________ is the diffusion of water across the cell membrane
osmosis
What organelle is responsible for the production of energy (ATP) in the cell?
mitochondria
Occurs when the plasma membrane surrounds a large substance inside the cell and moves it out of the cell.
Exocytosis
What is the function of the Golgi apparatus
Process and package proteins and other material to be shipped outside the cell
This process depends on molecule size and solubility
diffusion
Water moves into the cell when the solution surrounding the cell is (hypertonic or hypotonic)?
hypotonic (high free water concentration)
What is the difference between the smooth ER and the rough ER
The rough ER has ribosomes on its surface
Occurs when small molecules move across the plasma membrane with the concentration gradient, enlisting the help of channel proteins.
facilitated diffusion
What is the main function of the nucleolus
Produce ribosomes
Type of active transport that moves large amounts of fluid into or out of the cell
pinocytosis
Name two organelles that are only in plant cells, not animal cells.
Chloroplast and cell wall
