|
Plant and animal cells (eukaryotic cells) have a cell membrane, cytoplasm and genetic material enclosed in a nucleus. |
|
What is the basic structure of plant and animal (eukaryotic) cells? Recall structure of plant and animal cells as teams with whiteboards. |
|
|
|
Bacteria have cytoplasm and a cell membrane surrounded by a cell wall. |
|
What is the structure of a bacterial cell? GF - Justify why the majority of disease causing organisms are prokaryotic. |
|
|
|
Students should be able to demonstrate an understanding of the scale and size of cells and be able to make order of magnitude calculations, including the use of standard form. |
|
What is the order of magnitude of an ant, DNA, red blood cell, carbon atom and bacterial cell? |
|
|
|
Bacterial cells (prokaryotic cells) are much smaller in comparison. |
|
Are bacterial (prokaryotic) cells bigger or smaller than eukaryotic cells? |
|
|
|
In bacteria the genetic material is not enclosed in a nucleus. It is a single DNA loop and there may be one or more small rings of DNA called plasmids. |
|
What is unique about the DNA in a bacterial cell? Use plasticine to make a model of a bacteria cell.
Extension: make a model (scaled up) of an animal cell to visualise difference in size. |
