THINGS I GOT WRONG

Question 1

aerobic respiration equation

Answer 1

O2+glucose-> CO2+H2O

Question 2

photosynthesis equation

Answer 2

CO2+H2O -> O2 + C6H12O2

Question 3

why do plants do photosynthesis

Answer 3

to make glucose
from glucose they make carbohydrates
store as starch
make other carbon compounds

Question 4

describe how carbon in the atmosphere is cycled through living organisms

Answer 4

photosynthesis
Co2 taken through the leaves
to make glucose/carbs
to make proteins lipids
glucose stored as starch
Respiration
animals respire release CO2 atmosphere
Bacteria help decay
decomposed by microorganisms
Feeding
animals eat plants
plants have carbon inside
we can make carbon compounds too

Question 5

how do orchid adaptations help plants survive+ compete

Answer 5

bright colors attract pollinators
large quantities of pollen= more seeds/reporductuon
small sneers= travels further grow jew reads
many seeds= new plants outcompete other Sp / more survive

Question 6

4 marks evolution
how have purple orchids evolved from pale yellow ancestors

Answer 6

1. mutation in species
2. isolation OR change in env
3. purple ones survive and breed
4. pass on mutation
5. until they are so different they can’t breed w someone else(a new species)
