Answer:
Modes Of Nutrition
The process of obtaining food and utilizing it to grow, stay healthy and repair any damaged body part is known as nutrition. Plants produce their food by taking raw materials from their surroundings, such as minerals, carbon dioxide, water, and sunlight. There are two modes of nutrition:
Autotrophic – Plants exhibit autotrophic nutrition and are called as a primary producer. Plants synthesis their food by using light, carbon dioxide, water, carbon dioxide, or other chemicals.
Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
Conditions necessary for Photosynthesis
Sunlight
Water
Carbon dioxide
Chlorophyll
Steps in Photosynthesis
Absorption of energy from sunlight
Conversion of light energy into chemical energy
Hydrolysis of water into oxygen and hydrogen
Carbon dioxide is reduced to form glucose by utilizing chemical energy
Heterotrophic Nutrition in Plants
Some plants do not contain chlorophyll and depend on other plants for their food through the heterotrophic mode of nutrition. These type of nutrition in plants are referred to as Heterotrophic nutrition in plants, hence are called parasites.
Heterotrophic Plants
Listed below are different types of heterotrophic plants that are mainly classified based on their mode of nutrition:
Parasitic
Insectivorous
Saprophytic
Symbiotic
Parasitic Nutrition
Some heterotrophic plants depend on other plants and animals for nutrition. Such plants are known as parasitic plants. However, the host is not benefitted from the parasite.
For eg., Cuscuta, Cassytha.
plant prepared their food by using sunlight,water, carbon dioxide etc .
this process is also known as photosynthesis
