what is the balanced equation for respiration?

C₆H₁₂O₆ + 6O₂ → 6C0₂ + 6H₂O

what substances are in the blood

oxygen, carbon dioxide, glucose, hormones, electrolytes, proteins, urea

what is glucose used for?

energy, respiration, iron for haemoglobin and red blood cells, amino acids for protein synthesis, fatty acids for insulation, water for hydration and transport, protein for growth

difference between insect and wind pollinated flowers

stigma is feathery, has large surface area and is exposed, insect is sticky petals are absent/small and is not coloured, the filament is longer and exposed, pollen is light, dry abundant for wind and sticky for insect, stamen is inside the flower for insect, wind pollinated its exposed

difference betwen sexual and asexual flowers

no gametes, no fertilisation, mitosis, for asexual, offspring are clones, no genetic variation

how is yogurt made?

milk is heated for pasteurisation, which ensures bacteria is killed, the bateria lactobacillus is added, which a type of sugar called lactose to do anaerobic respiration, this produces lactic acid

difference between red blood cells and white blood cells

RBC has no nucleus, is smaller, has haemoglobin, has bi concave shape

nitrate role in plants

make amino acids which are building blocks for protein, which produce enzymes

calcium role in plants

bonds with pectin to make calcium pectate which holds cells together, affects the permeability of membranes

nitrate deficiency in plants

older yellow leaves, stunted growth

calcium deficiency

young yellow leaves which are crinkly and die back at growing points

magnesium role in plants

producing chlorophyll, needed for some enzymes to function and in the production of nuclei acids which helps with growth

magnesium deficiency in plants

leaves turn yellow and growth slow down

phosphates role in plants

needed to make DNA and cell membranes, needed for energy release and is also needed as part of the support substances in plant cells

phosphate deficiency in plants

dark green leaves with purple veins and stunted growth

what are the enzymes produced in the pancreas?

amylase, protease and lipase

why do plants need to photosynthesise?

to produce glucose for respiration
