Products of digestion are diffused into the surrounding cytoplasm and either stored or used for vital activity and growth. State the form in which the following are stored : (i) unused carbohydrates in plants (ii) the energy derived from food in humans. Food includes bacteria, unicellular plants (algae, diatoms, yeasts, etc.) They live in aquatic environments, and they are heterotrophs. Amoeba: Amoeba moves by forming pseudopodia. Respiration and excretion: takes place by general body surface through diffusion process. When a pseudopodium fuses with the food particle, it forms a food vacuole. The food goes through the cell mouth into the gullet. Soil pollution c. Water pollution d. Pesticides pollution Notes: students must use the separate answer sheet for the Dashain assignment. Introduction to paramecium nutrition : Paramecium nutrition is special in its own way. Food includes bacteria, unicellular plants (algae, diatoms, yeasts, etc.) Finally the undigested food materials is eliminated from the body through anal spot or cytoproct on ventral surface. Conjugation is considered to be an epi­sode in reproduction and not a mode of multiplication. The gametophyte produces gametes by mitosis while the haploid spores are produced by sporophyte following meiosis (reduction division). Give … 6. and small bits of animal and vegetables.
