It'll be something you remember pretty easily by the end of this unit because you get introduced to cells called phagocytes. What they do, eat things essentially, will give you that cue to remember. But as MM1 said, you definitely need to know it.

Phagocytosis is basically when bulk material is taken up by a cell as a solid yeah?
Any more detail required?
Also, what is the function of the nucleus? Its pretty simple but I am having trouble wording it :(

thanks

Yeah, that's pretty much it. Phagocytosis mainly involves cells and pieces of cells really. And nope, no more detail required other than perhaps how it works (which is the same as endocytosis because it is endocytosis).

That is a hard one to word, so I'll leave that to someone else for practice.

Controls all cellular activity within the cell [by controlling what proteins are synthesized?]

(Please quote me if I'm wrong/should use better wording haha)

Right track, but yeah, needs better wording.

Do we need to know what the cell skeleton is? Such as tubules, microtubules etc.
Also, how is everyone making their summary notes? Summarising the textbook chapter by chapter or summarising stuff they learn at school?

I think it has been said here before that this is no longer in the course. TO be honest, I didn't know it in year 12

oh really? That makes life so much easier :)
Is this correct? " Osmosis is the passive, net movement of water molecules across a semi-permeable membrane, from a hypotonic solution to a hypertonic solution."

The nucleus contains chromosomes that control the hereditary characteristics of an organism. DNA is mainly located in the nucleus and is responsible for protein synthesis and maintenance of the genetic features of an individual.

Maybe mention "free water molecules" instead, but otherwise it sounds like a good definition.

Good point. Ill add that in. Will this definition get me full marks?

How would you define it properly?


Also, what do we exactly have to know about the 'ATP-ADP cycle; factors affecting rate of energy transformations' which is in the current study design? I'm confused with what we are actually required to know.

Hmmm it's difficult. To be honest, I'm finding it a bit difficult myself to word it properly.

I'd say it's function is to store and synthesise hereditary information, but even that sounds a little shit.
