1.2 - Ultrastructure of cells
Assessment statements
DCS Topic Code | Statement | Guidance |
1.2.U1 | Prokaryotes have a simple cell structure without compartmentalization. | |
1.2.U2 | Eukaryotes have a compartmentalized cell structure. | |
1.2.U3 | Electron microscopes have a much higher resolution than light microscopes. | |
1.2.A1 | Structure and function of organelles within exocrine gland cells of the pancreas and within palisade mesophyll cells of the leaf. | |
1.2.A2 | Prokaryotes divide by binary fission. | |
1.2.S1 | Drawing of the ultrastructure of prokaryotic cells based on electron micrographs. | Drawings of prokaryotic cells should show the cell wall, pili and flagella, and plasma membrane enclosing cytoplasm that contains 70S ribosomes and a nucleoid with naked DNA. |
1.2.S2 | Drawing of the ultrastructure of eukaryotic cells based on electron micrographs. | Drawings of eukaryotic cells should show a plasma membrane enclosing cytoplasm that contains 80S ribosomes and a nucleus, mitochondria and other membrane-bound organelles are present in the cytoplasm. Some eukaryotic cells have a cell wall. |
1.2.S3 | Interpretation of electron micrographs to identify organelles and deduce the function of specialized cells. |
