Types of Transport
What is the job of the cell membrane?
To control what enters and exits the cell.
The RELEASE of large amounts of material by infoldings or pockets of cell membrane.
Exocytosis
In what organelle does photosynthesis take place?
Chloroplasts
In what organelle does cellular respiration take place?
Mitochondria
Stores the cell's DNA
Nucleus
List three types of passive transport
Diffusion, facilitated diffusion, osmosis
Taking material INTO the cell by infoldings or pockets of cell membrane.
Endocytosis
What types of cells have chloroplasts? List all that apply.
Plant cells only
What types of cells have mitochondria?
Plant AND animal cells
Structures within a cell that perform a specific function.
Organelles
A blue food coloring tablet is placed in a cup of vinegar and water. The blue tablet will dissolve and spread evenly throughout the liquid.
Is this diffusion or osmosis?
Type of transport across the cell membrane without using cellular energy.
Passive transport
What gas is removed from the atmosphere through photosynthesis?
Carbon dioxide
What energy storage molecule is produced at the end of cellular respiration?
ATP
Which organelle is responsible for making proteins?
Ribosomes
What macromolecule are the pumps and channels made of that help materials move from one side of the cell to the other?
Proteins
Process by which particles move from an area of high concentration to an area of lower concentration easily, without energy.
Diffusion
Why are photosynthesis and cellular respiration considered opposite processes?
The products of one are the reactants of the other. The equations are reversible.
How do the processes of photosynthesis and cellular respiration work together to make ATP?
Photosynthesis produces the oxygen and glucose that go into cellular respiration. Through cellular respiration, ATP is made.
Small, simple, no nucleus, no organelles
Prokaryotic cell
Draw a phospholipid on the board. Label the hydrophilic and hydrophobic regions.
Teacher discretion
Process in which molecules that cannot directly diffuse across the membrane pass through special protein channels from an area of high concentration to low concentration.
Facilitated diffusion
What is the chemical formula for photosynthesis?
Write it on the board.
Sun+ Carbon dioxide+ Water --> Oxygen + glucose
What is the chemical formula for cellular respiration?
Write it on the board.
Glucose + Oxygen --> Water + Carbon dioxide + ATP
Which organelle would be required for muscle cells, which use A TON of energy?
Mitochondria
