not es at ot 1n e - I j scie nce 10th ooso on hoi. LIFE PROCESSES Viruses show no molecular mouement in them until they infect a cell, that is why it is not known if they're aliue or not. Diffusion isnt enough to get oxygen in multi cellular organisms as cells may not be in direct contact with the enuironment, unlike in unicellular. Nutrition: Process of obtaining nutrients and transfering it from outside to inside the body is called nutrition Nutrients are substances essential for growth & deuelopment of body. Enzymes are bio - catalysts which break down food into simpler substances so that it can be digested. Autotrophic nutrition is when organisms manufacture their own food by photosynthesis. For example plants, blue-green algae. Euents in photosynthesis: Absorption of light energy by chlorophyll Conuersion of light energy to chemical Splitting of water molecules Into hydrogen and oxygen. Reduction of carbon dioxide to carbohydrates. ~j,r,.l 0 ~ ~ (:TitG3 (iTI] bi!.tUoo ~ CmI!oo tttllffl b [ ,I !filliGJ ((I )'lr, (fl!f,Jt] &4 (0 m ffl1Nu tt!lliW fjtJJm fuJ ffitf1i lb Gf,]!Y}, TJl ro,1hrtit.Jl ulill@tbJ cq]Nib mm ™.b o ~ ttljf4~it@ ~ t;.t.HbrJJ ~ ~NufuID ~ ~ lliJJ@lt,Jfil @lb ~ fuJ t4If1iiltffi fuJ ®fi1100 0 ~ \jfMtth t3 ~ ffl.rg r fkfuiUitl lht. 1;1, tA1filM3Jjiili ru ~ n:rm ~ w; tt Jil;E 0 LiG)m ™ ttillE o ~ fuJ -i!-~-~j-iI!-~ ~ [I{tjli lJli{- 0 utl~ ~ [email protected]© o[IB]i{ntkfurn,rrn o [J.m,r
