7. What is the difference between plants and animals with regard to nutrition?
Answers
Answer:
heterotypic nutrition in animals and autotrophic nutrition in plants
Answer:
1 ) Plants make their own food while animals have to rely on 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.
4) On the other hand, in animal nutrition, large food molecules are broken down into smellier soluble molecules. -
5) In humans proteins are broken down into amino acids, carbohydrates are broken down into glucose, fructose and galactose while fats are broken down into fatty acids and glycerol.
6) Thus the end products of animal/human nutrition are amino acids, simple sugars/ monosaccharides, fatty acids and glycerol.
7) The features/organs involved in the nutrition in plants are also different from that in animals.
8) In plant nutrition leaf plays an important role. Petiole, lamina, upper and lower epidermis, chloroplasts and mesophyll tissues are also essential in plant nutrition.
9) In contrast organs involved in animal/human nutrition include the mouth, buccal cavity, oesophagus, stomach, small intestine and large intestine.
