B.2 Plant Processes Flashcards
What is Transpiration?
evaporation of water from the plants leafs
What is capillary action?
water attracts to itself and moves up the stem
What is Osmosis?
water from the soil enters the roots (water goes where there is less water)
What is a Chloroplast?
structure in a leaf where photosynthesis occurs ( makes leafs green)
What is the formula for photosynthesis?
water + carbon dioxide + energy -> oxygen + sugar
what are pores?
tiny openings in a membrane that allows only some substances to pass through
What does concentration mean?
The amount of something in a solution.
What is diffusion?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
what is the purpose of having pores in a membrane?
It only allows only important substances to make it in and out of the plant cell.
What is active transport
Movement of substances using energy. Plants use active transport to absorb nutrients in the roots.
what is passive transport?
passive transport is a natural process where no extra energy is needed. Two examples are osmosis and diffusion.
How is diffusion useful in a plant?
It allows carbon dioxide to move into plant cells and oxygen to move out of plant cells.
