Homework…. Find a diagram of a plant and animal cell (textbook or internet). Redraw both cells and label them fully. Research the difference between a prokaryote and eukaryote cell. Put your info into a suitable table. Due: 15/09
Title: Cells… Lesson Objectives : 1. Can I name and identify cell organelles? Grade C 2. Can I compare and contrast prokaryotic and eukaryotic cells? Grade B/A Starter: Study your pics of cells….then label mine…
The type of cell you are currently familiar with:
Cell theory…. The basic principles of the cell theory are: All organisms are made of cells that resemble each other by having internal structures and a boundary These cells are always formed by the division of pre-existing cells Cells contain inherited information which determines their activity Given suitable conditions, cells are capable of independent existence Can you name the 7 characteristics all living things share?
Cell Structure… Given these principles of cells, biologists recognise two types of cellular structure: Prokaryotic cells (‘before the nucleus’) Eukaryotic cells (‘with a nucleus’) Virus particles do not fulfil the criteria of the cell theory and so are regarded as being non-cellular. Some texts may refer to their structure as being ‘akaryotic’ (without a nucleus)
Your homework…. What did you discover about Prokaryote cells?
