Passive Transport
What is not used in passive transportation
ATP Energy
What is the concentration gradient of active transport
Low concentration to high concentration (Against)
Define Osmosis
Water moving across the cell membrane
Why do grocery stores spray vegetables with water?
The water also keeps produce firm by entering plant cells via osmosis and restoring turgor pressure.
Which organelle controls what enters and exits the cell?
Cell membrane
What is osmosis?
Movement of water across the cell membrane without the use of energy
How does active transport differ from passive transport?
Active transport uses ATP energy
Define hypertonic solution
There is more concentration of water inside the cell rather than outside the cell causing water to move out of the cell
How do sports drinks help athletes after exercise?
The electrolytes and carbohydrates in a sports drink increase the solute concentration of the extracellular fluid. Water then moves from the areas of lower solute concentration (the blood) toward the higher solute concentration in the cells, balancing the fluid inside and outside the cells.
Which organelle packages proteins
Golgi Bodies
Name one example of passive transport.
Osmosis or facilitated diffusion
Name one type of active transport.
Endocytosis Or Exocytosis
What would happen to a cell if there is more concentration of water outside of the cell rather than inside?
The cell would swell
Why is it dangerous to drink seawater?
its high salt concentration creates a hypertonic solution, causing water to move out of your cells via osmosis, which leads to cellular dehydration and dehydration.
Which organelle of the plant cell captures sunlight for photosynthesis?
Chloroplast
Describe how diffusion works.
Molecules move from high concentration to low concentration
Compare endocytosis and exocytosis AND draw a picture
Endocytosis brings large molecules in Exocytosis gets rid of large molecules
Why do plant cells not burst when placed in pure water, but animal cells can?
The cell wall keeps them from bursting
If you sprinkle sugar on strawberries and leave them out, juice forms on the surface. Why?
Sprinkling sugar creates a high concentration of dissolved particles (solutes) on the strawberries' exterior. The water inside the strawberry's cells, in comparison, has a lower concentration of solutes.
Who released the song Espresso in 2024
Sabrina Carpenter
Explain why passive transport does not require energy.
because substances naturally move from an area of high concentration to an area of low concentration
Explain why a cell would use active transport instead of passive transport.
to move substances against their concentration gradient, or to transport large molecules like proteins and other macromolecules that cannot cross the membrane passively.
A student places a gummy bear in distilled water overnight. Predict what will happen and explain why.
When a gummy bear is placed in distilled water overnight, it will significantly increase in size, swell, and become much softer due to the process of osmosis.
Farmers sometimes lose crops after fertilizing too heavily because the soil water becomes too salty. Explain what happens to the plant cells.
When a farmer over-fertilizes, the salt concentration in the soil water becomes much higher than the salt concentration inside the plant's root cells. This causes water to leave the plant cells, a process that leads to dehydration, wilting, and, eventually, crop death.
What would happen if ribosomes stopped working in a cell?
the cell could not synthesize proteins, which would halt essential functions like metabolic processes, cell structure, and signaling.
