Plants make their own nutrients; humans must consume theirs.
|
|
Plant nutrition consists mainly of protein; human nutrition consists mainly of carbohydrates.
|
|
Plants absorb their nutrients from the soil; humans get theirs from food.
|
|
Plants cannot make their own food.
|
Detailed explanation-1: -Plants make their own nutrients; humans must consume theirs. b. Plant nutrition consists mainly of protein; human nutrition consists mainly of carbohydrates.
Detailed explanation-2: -Humans require proteins, carbohydrates, lipids, vitamins and mineral elements as their nutrients, while plants only require mineral elements for their growth and development. The mineral elements which humans need are directly and indirectly derived from various diets, which are produced from different crops.
Detailed explanation-3: -In what way does plant nutrition differ from human nutrition? Plants make their own nutrients; humans must consume theirs.
Detailed explanation-4: -1) Plants make their own food while animals depend upon the plants or other animals for food, 2) In photosynthesis plant converts carbon dioxide and water (in the presence of light energy and chlorophyll) to glucose, water and oxygen. 3) Hence the end products of plant nutrition are actually glucose and oxygen.
Detailed explanation-5: -Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.
