Study Notes
- Plants are autotrophic organisms, producing their own food through photosynthesis.
- Photosynthesis requires energy from light, water, carbon dioxide, and minerals from the soil.
- Macronutrients essential for plant growth include nitrogen, phosphorus, and potassium, which are crucial for amino acid synthesis, protein production, energy production, root development, flower/seed formation, water balance, transport, and enzyme activation.
- Micronutrients essential for plant growth include iron, zinc, copper, boron, manganese, and molybdenum, which are involved in photosynthesis, enzyme function, protein synthesis, plant defense, cell wall formation, sugar metabolism, nitrogen fixation, and flower/seed formation.
- Autotrophic nutrition is the mode of nutrition in which plants produce their own food through photosynthesis.
- Heterotrophic nutrition is the mode of nutrition in which plants obtain their nutrients by decomposing organic matter or parasitizing other organisms.
- Roots are responsible for absorbing water and minerals from the soil.
- Xylem transports water and minerals from roots to shoots.
- Phloem transports sugars, amino acids, and other organic compounds produced by photosynthesis.
- Symplast refers to the living contents of plant cells, where nutrient transport and storage occur.
Learn about the essential nutrients, modes of nutrition, and processes of nutrient uptake and transport in plants. Understand the importance of macronutrients and micronutrients, and how plants produce their own food through photosynthesis.
