Answer:

Because green plants are capable of making their own food, they are called autotrophs.

  1. Photosynthesis. Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
  2. Plants absorb sunlight and turn that energy into food; the process is known as photosynthesis. This is a compound word made up of photo (which means "light") and synthesis (which means "to put together")
  3. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. ... Two types of chlorophyll exist in the photosystems of green plants: chlorophyll a and b.
  4. Fungi are mostly saprobes (saprophyte is an equivalent term): organisms that derive nutrients from decaying organic matter. They obtain their nutrients from dead or decomposing organic material derived mainly from plants.
  5. Solar energy gets converted by chlorophyll. Glucose is stored in the form of sucrose.
  6. The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.

  1. Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2. During this process, organisms such as plants go through the light-dependent and light-independent reactions to convert carbon dioxide and water into sugars and oxygen.
  2. A lichen is not a single organism; it is a stable symbiotic association between a fungus and algae and/or cyanobacteria. ... The lichen symbiosis is thought to be a mutualism, since both the fungi and the photosynthetic partners, called photobionts, benefit.
  3. a) Nutrition is defined as the processes by which an animal or plant takes in and utilises food substances. Essential nutrients include protein, carbohydrate, fat, vitamins, minerals and electrolytes. Normally, 85% of daily energy use is from fat and carbohydrates and 15% from protein.

b) Stomata absorb carbon dioxide from air for photosynthesis. Stomata facilitates exchange of gases and transpiration.

4. Rhizobium is a bacterium found in soil that helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development.
