Organisms In The Environment Flashcards
the process of photosynthesis is what?
carbon dioxide + water + light energy –> glucose + oxygen.
what is the function of the stomata?
allows gasses to move in and out of the cell.
when something is short supply to the cell or organ it is known as?
the limiting factor.
what are the three most common limiting factors for photosynthesis?
Light, Temperature and carbon dioxide levels.
carbon dioxide in photosynthesis is needed for?
to create glucose.
how do plants create amino acids?
they combine glucose sugars with nitrate ions and other mineral ions found in soil.
how is starch stored in plants?
either in the form of bulbs or tubers.
how can humans make the most of photosynthesis?
they can change the environment the plants are kept in.
how can we control the temperature of the plants environment
we can stick them into greenhouses or polytunnels, this makes the environment a lot more controllable.
what is the name of the technology which allows plants to grow on water (contains all the ions that the plants need)
hydroponics
chemical reactions are controlled by what?
enzymes
