I'm a parent and I think the teacher had been a bit harsh with marking most of these questions but can someone help me answer the very last question on the paper please (where someone has written SP against it). Is the answer mitochondria?

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Homework questions are off-topic on Biology unless you have shown your attempt at an answer. For more information see our homework policy." – rg255, AliceD, anongoodnurse
So, to go through the question in total:
(a) Part A nucleus is correct, but Part B ist the cytosol/cytoplasm, as the line does not stop at the border, but goes through it and ends in the gray part of the cell.
(b) For part C, it is the same problem as in your first question. Yes, the picture may be a plant cell, however, upon this drawing one cannot differentiate a mitochondrium from a chloroplast. In my opinion, a good teacher should have marked this answer as correct, even if he/she wanted to hear the other possibility. Part D is correct.
(c) 'Photosynthesis takes place here': Photosynthesis takes place in the chloroplasts. Mitochondria would have been correct, if the teacher would have asked for the respiratory chain or for the often in school simplified powerhouses of the cell. 'Many of the cell's chemical reactions take place here': I think, the teacher wanted to hear the cytosol as answer.
