Essay on autotrophic nutrition

Heterotrophic Nutrition Heterotrophic Nutrition Every non-autotrophic organism which depends on others for their food is called heterotrophs. Heterotrophs include every animal and non-photosynthetic plant which are unable to prepare organic molecules on their own. Heterotrophic nutrition can be classified into three types, based on the ways in which organisms obtain their food: Saprophytic Nutrition Saprophytes animals which follow saprophytic nutrition feed on dead and decayed organisms for energy.

Essay on autotrophic nutrition

The literal meaning of this term is self-nutrition. Autotrophic nutrition is a process where the organism prepares their food from the simple inorganic materials like water, mineral salts and carbon dioxide in the presence of sunlight. All the green plants possess an autotrophic mode of nutrition.

The autotrophic organisms contain a green colored pigment called chlorophyll which helps in trapping energy from the sun. They prepare their own food by utilizing the solar energy, water, and carbon dioxide by the process of photosynthesis. This results in forming of glucose. Plants like blue-green algae and cyanobacteria could be considered as the example of autotrophic nutrition.

Photosynthesis Photosynthesis is a process to convert the solar energy into chemical energy to synthesize starch. Different parts of a plant play different roles to complete this process.

Extraterrestrial life, also called alien life (or, if it is a sentient or relatively complex individual, an "extraterrestrial" or "alien"), is life that occurs outside of Earth and that probably did not originate from hypothetical life forms may range from simple prokaryotes to beings with civilizations far more advanced than humanity. The Drake equation speculates about the.

Leaves — They are considered as the food factories of the plant. Stomata— It is present in the lower epidermis of the leaf which uses carbon dioxide from the air. Roots — They absorb minerals and water from the soil and transport it to different parts of the plant.

Leaves of the vascular plants have a special structure known as chloroplasts which possess chlorophyll. Plants synthesize glucose with the help of carbon dioxide and water in the presence of sunlight. The stomata present in the leaf releases oxygen and water as a by-product during the daytime.

The synthesized food is transported to different parts of the plant for storage and utilization. These green plants prepare proteins using nitrogen which could be obtained from the soil.

All the minerals which are dissolved in water are used to convert sugar into proteins, fats, and carbohydrates. These food components act as the source of energy for other heterotrophic animals and plants. Glucose is synthesized by this process and converted into different compounds like cellulose and starch which is stored in different parts of the plant.

What are the differences between Hetrophic & Autotrophic nutrition? -

Photosynthesis: Green plants, which are autotrophic, synthesize food through the process of photosynthesis. Devil In The Dark () The Horta was an example of Silicon life.; Now we are really sailing off into terra incognito. "Here be dragons" and all that. But if you have starships, you almost have to have aliens (Isaac Asimov's Foundation trilogy being the most notable exception).The "science" is called Astrobiology, the famous "science in search of a subject".

The parasitic nutrition is that nutrition in which an organism derives its food from the body of another living organism (called its host) without killing it. The organism which obtains the food is called a 'parasite', and the organism from whose body food is obtained is called the 'host'.

The alga Cyanophora, a glaucophyte, is thought to be one of the first organisms to contain a chloroplast. The glaucophyte chloroplast group is the smallest of the three primary chloroplast lineages, being found in only 13 species, and is thought to be the one that branched off the earliest. Glaucophytes have chloroplasts that retain a peptidoglycan wall between their double membranes, like.
