Plant Processes Flashcards
(27 cards)
Underground pathways that absorb water and nutrients from the soil
Roots
Above-ground “highway system” for plant nutrients and water
Stem
Channels that allow the transportation of water and nutrients in plants
Vascular Tissue
The force that causes water molecules to stick to other water molecules
Cohesion
Water molecules sticking to other surfaces, such as xylem walls.
Adhesion
The property of water that causes it to move up a tube against the force of gravity.
Capillary action
The evaporation of water through the stomata of leaves
Transpiration
The rigidity/firmness of plants due to water content.
Turgor Pressure
Plant growth response caused by environmental stimuli
Tropism
A plant’s response to LIGHT
Phototropism
A plant’s response to GRAVITY
Geotropism
Environmental change that cause a reaction in an organism
Stimuli
Water passageways made of non-living cell in plants that run one-way from root to leaves.
Xylem
Glucose passageways made of living cells in plants that run both directions to all parts of the plant
Phloem
Plants with soft green stems that are usually rigid when healthy, due to increased turgor pressure
Herbaceous
plants
Tiny openings in leaves that allow for transpiration of water and the exchange of gases
Stomata
Cells that control the opening and closing of the stomata
Guard Cells
Process by which cells get energy from glucose. It occurs in mitochondria.
Respiration
The process of a plant using sunlight to make glucose and oxygen. It occurs in chloroplast.
Photosynthesis
Substances that starts the chemical reaction
Reactant
Raw materials (CO2 , H20) for photosynthesis.
Reactant
materials created by photosynthesis. (Glucose and O2)
what is made during a chemical reaction.
Product
Energy from light
Radiant Energy
Energy from food and fuel (in the case of plants, from glucose)
Chemical energy
