Study Notes
Photosynthesis and Nutrition
- Food is essential for all living organisms and contains nutrients such as carbohydrates, proteins, fats, vitamins, and minerals.
- Nutrients enable living organisms to build their bodies, grow, repair damaged parts, and provide energy.
- Nutrition is the process of obtaining and utilizing food by an organism.
- Autotrophic nutrition is when organisms can make their own food from simple raw materials, while heterotrophic nutrition is when they depend on others for it.
- Photosynthesis is the process by which plants synthesize their food using carbon dioxide, water, and sunlight in the presence of chlorophyll.
- Leaves are the food factories of plants, and chlorophyll helps capture the energy of sunlight.
- Carbon dioxide and water are the raw materials for photosynthesis, and the presence of sunlight and chlorophyll is necessary.
- Water and minerals are absorbed by roots from the soil and transported to other parts of the plant by vessels.
- Carbon dioxide enters the leaves through stomata, surrounded by guard cells.
- Chlorophyll gives leaves their green color and helps capture solar energy for photosynthesis.
- Photosynthesis supplies food and oxygen needed by all living organisms for respiration.
- Life on earth would not be possible without photosynthesis.
