Osmosis
Does osmosis need energy to work?
No, it's a passive process, requiring no energy from the cell.
What is diffusion?
The movement of particles moving from high to low concentration
What is the cell theory?
The cell theory is a theory in biology that describes the basic properties of all living organisms
When plants absorb the water through their roots what is this called?
Osmosis
What is osmosis?
Osmosis is the natural movement of water across a semipermeable membrane from a high-water concentration area to a low water concentration.
Does diffusion require energy?
No, diffusion is a form of passive transport and does not require cellular energy
How many cells does the human body have?
30-40 trillion
Plants absorbing water via roots, wilting leaves, getting thirsty after eating salty food, what is this called?
Osmosis
What's the difference between osmosis and diffusion?
Diffusion is the movement of any particles from high to low concentration; osmosis specifically refers to water movement across a semipermeable membrane.
If the temperature decreases, the rate of diffusion will?
It will decrease
What organelle is the powerhouse of the cell?
The Mitochondria
Imagine you pour vanilla in a ballon. Why can you smell the vanilla from outside the ballon?
The vanilla particles diffused through the ballons material
Why can't we drink ocean water?
Because drinking it will cause the water to move out your body cells and into your digestive system.
Why is the cell membrane semi permeable?
Its semi permeable because this is essential for the cell to survive and function by controlling what can come in and out.
What is ATP?
It is the primary energy currency for all living cells
Why when you put food coloring in water why does it spread out?
It spreads out due to diffusion moving the particles from high concentration to low concentration
Why do plant and animal cells need osmosis?
They need osmosis to regulate water balance, making cells don't break or burst by moving water in and out across semipermeable membranes .
An animal cell surrounded by fresh water will burst because the pressure causes what?
The water to move into the cell
Why do plant cells have way bigger vacuoles than animal cells?
It is because they need it for structural support, to store water, nutrients, and waste.
How does oxygen get from your lungs into your bloodstream?
The oxygen molecules move by diffusion from the air in the lungs where concentration is high to the where the concentration is low.
