This homework?

If not homework, then certainly revision.

Have a go yourself. If you don't know, look it up in the notes you will (should) have taken from the lesson. Otherwise, search for, eg "cellular membrane" and see if you can find out what it does.

There's nothing gained by someone else completing this for you.

why are you finding this difficult ?
we will help with difficulties
but here - you just read the chapter

actually the questions arent bad
No5 - does a nucleus capture sunlight - no that is a chloroplast
does it - get rid of waste - no that is exocytosis of a vesicle
does it produce energy - no that is a mitochondria

honestly you look at a diagram of a cell
and learn all the names and what they do
we all did

and as I keep saying a please and thank you never come amiss

This takes me back, and I could still tell you all the answers but they won't stick. If you do the work yourself you are more likely to remember the answers when they come up in exams. Thank you for bringing back memories of my school days though.
