GCSE Additional Science? Unit 1

That's how I felt, for example the 0.04 to 0.4 graph??

That was ridiculous- I was so confused- just made the whole thing up

Oh was that the one where you had to like add a line to the graph? Co2 or whatever? - if so, what did you put?

Yeah it was- I put the line going down steeper and then leveling off at like 90 light intensity after 9 days with the theory that if the co2 increased by x10 it would reduce the amount of days needed by half but the light intensity would not affect it as much (as in it would level off later) as the co2 would not be a limiting factor anymore.

Sorry if this doesn't make much sense but tbh I didnt really know what i was talking about either

Oh I get it. Yeah your answer seems pretty scientific, probs right :P the question way just way too confusing for me

What did you put for the 6 marker?

Said about how tissues are arranged into organs, organs into organ systems

Plants:
Organs: Stem, Roots and Leaves
Tissues: Mesophyll- Photosynthesis, Xylem- Water, Phloem- Minerals and Epidermal- Covers Plants

Animals:
Used digestive system example:
Tissues: Epithial- Covers inside and outside of stomach, Glandular- secretes digestive juices, Muscular- Churns food and contracts

Organs: Stomach- digest food, Small Intestine- Absorbs solouble molecules, Liver-produces bile, Large intestine- absorbs water

Probably wrote way too much what did you write?

Mentioned a couple of the tissues for plants and animals and explained them, but I didn't write near as much as you did lol. Didn't write anything about organs though. Hopefully i'll get a few marks

Are you all edexcel?
