Active Transport Flashcards
What’s the active transport concentration?
•Low to high concertration
What type of membrane does active transport occur across?
•A semi permeable membrane
In order for a plant cell to go through the process of active transport what will it require?
•Energy
What is transpiration?
•The process of movement of water up a plant.
What do root hairs do through active transport?
Take in minerals and water
How do minerals exit a root hair cell?
By diffusion
What can minerals be absorbed from?
Dilute solutions
How are minerals absorbed?
Against a concentration gradient
Definition of active transport
A substance being absorbed against a concentration gradient from a low to high concentration
What are minerals essential for?
Growth
What does active transport require?
Energy from respiration
Why can’t root hair cells use diffusion to absorb water and minerals?
The concentration in the root hair cell is usually higher than the surrounding soils concentration so the minerals can only diffuse from a high to low concentration and therefore can’t diffuse.
What does active transport take from the gut?
Gluecose
Why is it taken from the gut into the bloodstream?
Because there is a lower concentration of nutrients in the gut than in the blood.
What happens when there is a higher concentration of amino acids and gluecose in the gut?
They diffuse naturally into the bloodstream
