1. The mode of nutrient procurement for a mutlicellular animal is ingestion, while a plant takes water and minerals from the soil by osmosis, so does a unicellular cell.
Mechanism of Gas exchange in animals, plants and in a unicellular organism is diffusion
Photosynthesis happens in green plants as well as in unicellular organisms like green algae with the help of chlorophyl
Movement by animals will be with the help of their skeletal system while plants are immobile and actin filaments help in the cellular movement
Animals have skeletal system for the support while plants and cetain unicellualr organisms have cell wall
Animals have sexual reproduction, while plants have both asexual as well as sexual means of reprodcution and unicellular organisms have mostly asexual reprodcution but there are certain unicellular microbes that have sexual method of reproduction.
2. Symbiosis is the association or living relationship between two species in which both the species are benefitted.
for example the association between legumious plants like pea plants (pisum sativum) and the bacterial species rhizobium ( like Rhizobium leguminosarum) that lives in the plant's root nodules. The bacteria fix atmospheric nitrogen making it available to the plant, there by helping the plant to live with out nitrogen containing fertilizers.
Another example is Fibrobacter succinogenes living in the gut of ruminant animals like cow, goat etc. the bactrium helps in the digestion of cellulose, a component of plant cell wall, wthe the help of the enzyme cellulase produced by the bacterium, while the baterium will get to house in the gut with food.
3. Biotechnology is the field of biology which employs genetically modified biological systems like unicellular organisms or animals or plants or the one of their process alone to manufacture products like drugs, antibiotics, vitamins, enzymes and many other useful materials for the human kind
Industrially many pharmaceuticals like antibiotic, different kinds of drugs are developed from genetically engineered
microbes.
Geneticaly modified crops and plants have been used to produce large amount of food materials by the food industry
genetically modified organisms are used in bio leaching of metals from metal ores
