defenition
define respiration
1 mark
a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

assimilation
a part of holozic nutrition
steps of respiration
explain thestep 1 of respiration
steps of respiration should be explained
breathing is a physical change taking oxygen rich air and give out carbondioxide rich air
breathing
steps of respiration
explain thestep 2 of respiration
steps of respiration should be explained
excahnge of oxygen and the carbondioxide into the body fluid across the body
gascious exchange
steps of respiration
explain thestep 3 of respiration
steps of respiration should be explained
releasing energywith every cell of the body due to the chemical change taking in glocuse
cellular respiratoin
types of respiration?
aerobic and anaerobic respiration
difference
differenciate between aerobic and anaerobic respiration
4 points
aerobic
1. in the presence of oxygen
2. glocuse + oxygen->carbondioxide+water +energy
3. 1 glocuse molecule produces 38 atpenergy
4. more efficiant
anerobic
1. in the absence of oxygen
2. glocuse–>lactic acid+energy
or
glocuse —>ethyle acid + co2+energy
3.1 glocuse molecule produces2 atp energy
4.less efficiant
amobea
how does amobea take in oxygen
through dissolved water
explanation
respiration of amobea
3 marks
Oxygen is entered by diffusion from sell wall into the body.
In return co2 formed when it combines with glocuse to release atp energy co2 and water vapour. Carbondioxide produced during respiration difuses out of the amobea cell into water.
you can try to compress in the exam if for lesser marks
plants
What is the microsopic pores which is used in respiration?
and is there any altranitive for breathing?
stomata
yes, root hair
How are earth worms important?
two pointer
- churns the soil and this produces air traps
- it enriches the soil with nitrogen in simpler forms
lenticles
What does this do and what is it?
2 pointer
- lenticles are present on the tree trunk.In absence of stomata the breathe
- plants being autrotrphs during the day they van take in co2
discribtion
describe the stomata structure
2 marks
stomata is present on the leaf lamina ,they are microscopic substances with 2 guard cells and stomatal porewhich help in exchange of gases.
finnally humans
tell the order of organs for human
- nostrils
- nasel passage
- nasel cavity
- pharenx
- lenyx
- trachea
- bronchii
- lungs
- bronchioules
- alveoli
where is the respiratory system present? protected by the rib cage
it is present in the chest cavity protected by the rib cage
what happens to different organs during inhalation
ex. diaphram –> dash
4 organs
lungs—->expands
ribcage—->moves upward
diaphram—>contracts
chest cavity—>volume increases
this can be written in a table
what happens to different organs during exhalation?
ex. diaphram –> dash
4 organs
lungs—->contracts
ribcage—->moves downward
diaphram—>expands
chest cavity—>volume decreases
this can be written in a table
What is the significance of floating ribs?
it makes it easy for the lungs to expand and contract during respiration.
What are the similarities of inhalation and exhalation?
-both are physical changes
-both are a part of breathing
-both are interactions of the surroundings
