Study Notes
Plant Structures and Processes
- Seed plants are the largest group of plants. Each seed plant part has specific functions.
- Roots absorb water and nutrients, anchoring the plant.
- Stems transport water and food, supporting leaves and flowers.
- Leaves produce food for the plant, exchanging gases (oxygen and carbon dioxide) and allowing water to exit.
- Flowers are reproductive structures.
- Seeds contain an embryo and a food supply for the developing plant.
Moving Water in Plants
- Osmosis: A type of diffusion where water moves through a selectively permeable membrane.
- Capillary action: Water is attracted to itself and to the tube walls, moving it upward.
- Xylem: Plant tissue that transports water from roots to leaves.
- Transpiration: The loss of water through evaporation from leaves.
- Active transport: Moves substances against a concentration gradient, needing energy.
Plant Food Production
- Chlorophyll: Pigment that makes leaves green, trapping sunlight for energy.
- Photosynthesis: Process that converts light energy into chemical energy (sugar).
- Ingredients for Photosynthesis: Carbon dioxide and water
- Products of Photosynthesis: Sugar and oxygen.
Using Food in Plants
- Cellular Respiration: A process where plants release stored energy from sugar in the presence of oxygen.
- Products of Cellular Respiration: Energy, carbon dioxide, and water.
