Study Notes
Nutrition in Plants
- Plants are the only organisms that can prepare their own food using water, carbon dioxide, and minerals from their surroundings.
- Autotrophic nutrition is the mode of nutrition in which organisms make their own food from simple substances.
- Plants are called autotrophs, whereas animals and most other organisms that take in food prepared by plants are called heterotrophs.
Photosynthesis — Food Making Process in Plants
- Leaves are the food factories of plants, where raw materials like water, carbon dioxide, and minerals are converted into food.
- Water and minerals from the soil are absorbed by the roots and transported to the leaves through vessels.
- Carbon dioxide is taken in through tiny pores on the surface of leaves, surrounded by 'guard cells', called stomata.
- Chlorophyll, a green pigment in leaves, helps capture the energy from sunlight, which is used to synthesize food from carbon dioxide and water.
- Photosynthesis is the process of synthesizing food in the presence of sunlight, and it requires chlorophyll, sunlight, carbon dioxide, and water.
- Photosynthesis is a unique process that captures solar energy and stores it in plants in the form of food, making the sun the ultimate source of energy for all living organisms.
Importance of Photosynthesis
- Photosynthesis is essential for the survival of almost all living organisms, as they directly or indirectly depend on the food made by plants.
- Oxygen, which is essential for the survival of most living organisms, is also produced during photosynthesis.
Test your knowledge on the transport of materials in plants, focusing on the special ability of leaves to synthesize food through photosynthesis. Explore concepts such as chlorophyll, sunlight energy utilization, and food synthesis.
