Transport systems
The movement of particles from a region of high concentration to a region of low concentration.
What is diffusion?
Soluble food materials made in photosynthesis
What does Phloem transport?
Water and mineral salts
What does the xylem transport?
release of energy in the form of ATP
What is the function of respiration?
What is Osmosis?
Long, narrow tubes with perforated sieve plates along their lengths.
What are phloem sieve tubes?
dead cells, bands of lignin
What is the Xylem made up of?
Carbon dioxide and water
What are the waste products of water?
The movement of particles down a concentration gradient using energy.
What is Active Transport?
Contains nucleus which controls the functioning of both cells.
What is the companion cell?
A chemical that strengthens the xylem so that it can help support the plant.
What is lignin?
Large surface area, moist,thin walls, access to air (gases)
What are features of gaseous exchange surfaces?
The upward movement of water through a plant due to the evaporation of water on leaves.
What is transpiration?
Structure with holes to allow soluble foods to pass through.
What is the sieve plate?
Long, narrow, hollow tubes formed from elongated cells.
What are Xylem vessels?
Lactic acid and ethanol
What are the products of anaerobic respiration? (in plants and animals
The transport of sucrose and other substances like amino acids around the plant.
What is translocation?
a strand of conducting vessels in the stem or leaves of a plant, typically with phloem on the outside and xylem on the inside
What is the vascular bundle?
a temporary oxygen shortage in the body tissues arising from exercise.
What is oxygen debt?
