prokaryote: smaller ribosomes.
no nucleus
no membrane bound organelle.
no CELLULOSE cell wal
have mesosomes and slime capsule

Plant cell have cell wall animals dont
anmal cells have centrioles plants dont
plant cells have large central vacuole. animals have small ones.
plant cells have chloroplast animals dont

water is a solvent and hence a medium for metabolic reactions and is also a transport medium.
water has high specefic heat capacity and thus provides stable environment for organisms

I am sorry. there is too much info. i cant state it all here. you have to read the book.

this is all present in OCR and explained as clearly as possible. Instead of spamming the forums begging people to help you why don't you actually READ THE FREAKING BOOK?!?

oh my god there is LITERALLY a sub heading in transport in plants that says "unloading of sucrose"

READ IT JEEZ!

I'm pretty sure I'm not the idiot here /:

It's like maybe 5 lines, not really hard to make points out of that

no double membrane-bound organelles ;
no, nucleus / nuclear membrane / nuclear envelope / nucleolus ;
A DNA lies free in the cytoplasm
no mitochondrion ;
mesosomes ;
no (large) vacuole ;
no, ER / RER / SER ;
no Golgi (body / apparatus) ;
smaller / 70S / 18nm, ribosomes ;
cell wall made of, murein / peptidoglycan / different compounds (from eukaryote) ;
circular DNA / plasmid(s) / no linear DNA ;
no histones / not complexed with proteins ; A naked DNA / no chromosomes
AVP ; e.g. pili / no 9+2 microtubule pattern
mark scheme for " ways in which a prokaryotic cell differs from eukaryotic (yeast like fungus develops during AIDS)"

Effect of temperature on enzymes:
at low temperature the reaction takes place very slowly, substrate molecule wont often collide with active site of enzyme and so binding between substrate and enzyme is rarest at low temperature. as temperature rises, enzyme and substrate molecule move faster, thus collisions happen more frequently and the most at 40^c. as the temperature continues to increase, the speed of movement of substrate and enzyme also continues to increase.but after certain temperature(i.e after 40^c), they vibrate so energetically that some of the bonds holding the enzyme molecule in its precise shape begin to break. the enzyme molecule begin to lose its shape and is said to be denatured and which usually stops the reaction to occur. :friends:
