Peptidoglycan 1 of 16 The internal membranes inside chloroplasts form flattened sacks - what are these sacks called? Thylakoids 2 of 16 What is exocytosis? When materials are transported out of the cell via secretory vesicles 3 of 16 What are lysosomes? Specialised forms of vesicles containing hydrolytic enzymes (digestive enzymes) 4 of 16 During transcription, why is information from DNA copied onto RNA? DNA is too large to leave the nucleus so its information is copied onto RNA which is small enough to leave through the nuclear pores 5 of 16 The fluid interior of mitochondria is called? The matrix 6 of 16 What are microtubules? A component of the cytoskeleton that forms a scaffold like structure that determines the shape of the cell 7 of 16 What is the name of the dark region within the nucleus? The nucleolus 8 of 16 What is the difference in structure between the smooth endoplasmic reticulum and the rough endoplasmic reticulum? The rough ER has ribosomes attached to it, and the smoothh ER does not 9 of 16 What kind of arrangement do the microtubules in cilia have? A 9+2 arrangement 10 of 16 Where are proteins synthesised? On the ribosomes bound to the endoplasmic reticulum 11 of 16 I'm an organelle found in plant cells. I contain an inner membrane that's arranged in flattened sacs. Which organelle am i? The chloroplast 12 of 16 What are histones and whats there relevance? Histones are proteins that form chromatin 13 of 16 Why are chloroplasts only found in plant cells? Because they're the sight of photosynthesis 14 of 16 How is DNA arranged in prokaryotes and eukaryotes? Prokaryotes - circular Eukaryotes - linear 15 of 16 How is the size of ribosomes in prokaryotic cells determined? Its determined by the rate in which they settle or form a sedimate in solution 16 of 16
