nutrition Flashcards
auto trophic hetero torpic
what is photosyntheis equation and who proposed it and their opinion
6CO2 +12H2O C6H12O6 + 6H20 +6O2 and its was proposed by CB van neil in 1931
who discovered chloroplast? and other pigments
pallletier and caventour in 1817 discovered chloroplast but didnt knew the location, other pigments are carotenoids and phycobilin
MR, for presence of starch
thin leaves, methylated spirit, iodine solution beaker, boiling test tube, tripod stand, bunsen burner, asbestos gauze, watch glass, dropper
priestly experiment
to proof air is essential for plant growth, 1770 performed series of exp in 1774 discovered oxygen but name was given by levoisier in 1775
mint plant, candel, bell jar, mouse
MR, to prove CO2 is essential for photosynthesis
iodine solution, potassium hydroxide (KOH) destarched potted plant, wide mouth bottle, split cork, petridish
MR, to prove O2 is produced in photosynthesis
hydrilla plant, water, insence stick, beakers, funnel, testtube, match box
MR, to prove sunlight is necessary for photosynthesis
destarched potted plant, black paper, iodine solution, stapler
who discovered the location of chloroplast
julius von sach in 1883, not spread in entire plant only in speciall organell inside leave
structure of chloroplast
stroma, stroma thyllacord, grana, thallycords, inner/outer membrane
light dependent reaction is also known as
photochemical reaction
light independent reaction is also known as
biosynthetic phase
describe 3 steps in light dependent reaction
1) absorbs photons and activates
2) breaks down H20 in H+ and OH- ions
3) takes OH- to makes H2O and O2
steps in light independt reaction
H+ is taken by NADPH and uses its hydrogen to undergo changes to make starch/ glucose
types of heterotrophic nutrition
1)saprophytes- moulds, yeast, mashroom
2)parasitic- lice, leaches, tape worm
3) holozoic- humans, animals, ameoba, paramecium
ingestion, digestion, absorbtion, assimilation, excreation
nutrition in ameoba
pseudopodia
nutirtion in paramecium
cillia, cytostome, anal pore
disgestive system are divided into
2 parts alimentary canal, digestive glands
name 5 digestive glands
slivary glands- submandibular- side of jaw
sublingual- below toung
parotid- side of ear
produce enzymens- amylase, slivary amylase, phytin
gastric gland- wall of stomatch
liver- bile juice/ no enzymes
pancreas-
intestinal glands
flow chart of human digestive system
mouth, buccal cavity, pharynx, oesophagus, stomatch, duodenum- phytoric spincher liver panchreas, small intes, large intest, rectum, annus
causes of vomitting
over eating, posinious food, high fat,
how to avoid indigestion
proper balance diet, mastification of food, avoid excersise soon after eating, drinking water
what is malnutirition
eating of food which dosn’t have one or more them one nutrition needed
reasons of malnutirition
1)poor health
2)full starvation
3)lack of awareness of balance diet
4)socio economic factors
types of malnutirion and their diesases
protein malnu- kawashiorkar
calorie malnu- obesity
protein/ calorie malnu- marasmus
