Osmosis and active transport Flashcards
1
Q
What does a root hair cell absorb?
A
Water and mineral ions from the soil.
2
Q
What is active transport?
A
It is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration.
3
Q
What do particles do in active transport?
A
They move against the concentration gradient- and therefore require an input of energy from the cell.
4
Q
In humans, when does active transport take place?
A
It takes place during the digestion of food in the small intestine.
5
Q
What are carbohydrates broken down into?
A
They are broken down into simple sugars such as glucose.
6
Q
What is osmosis?
A
It is what happens when water molecules pass through a partially permeable membrane.
