7A CELLS topic

You have been given a CONCEPT MAP which has been made by a Year 7 group to help them to
remember the main facts about cells.

Unfortunately, they have NOT included all the information they need AND some of the
information is NOT correct.

YOU HAVE A CHOICE:
EITHER
   Try to IMPROVE and CORRECT the concept map. Make sure that you indicate with a TICK
    those parts that you think are CORRECT and a CROSS beside any part that you think is
    INCORRECT. You may ADD as much detail as you like in the form of words or drawings.

OR
   Develop your OWN concept map including as much information as you can in words and/or
    drawings.
LEVEL DESCRIPTION              (complex for cells as higher level concept however can make judgment on ability to
extract information, recognise words and add information)

Level 3     Will not recognise that some parts are incorrect and will try to correct information that is already
correct, will tick most parts, will add little extra information but may add diagrams of cells or simple descriptions
e.g. Sperm cell for making babies.
 Own concept map will be a COPY of the one given with some drawings.

Level 4     Will use more scientific words in added details eg. Sperms used for reproduction, should spot that
“hairy” cell is not scientific but may not know correct term, will identify most correct parts, will not identify cell
wall/membrane as incorrect or skin. Should recognise that “dots in cell” is not scientific enough but may not
correct appropriately.
Own map will contain all keywords with an attempt at description.

Level 5     Will recognise that cell wall and cell membrane are in wrong areas and may include fairly accurate
drawings of plant and animal cells.
Must add that tissues are a collection of similar/same cells. Should recognise skin as incorrect and add suitable
tissue eg. Muscle, nerve
Add simple detail about function of cell parts e.g. chloroplasts used to produce food, vacuole full of cell sap etc

Level 6     Add more detail about parts of cell re. Nucleus..Controls the cell (not brain), chloroplast is green used in
photosynthesis, cell membrane controls what enters and leaves etc.
Add ciliated cell and detail about functions of cells eg. Used to filter the air, carries oxygen around the body (red
blood cell etc)
Most of drawings more accurate showing structure
Level 7 Add more explanation re. HOW cells are adapted for function.          Add detail re. cell division or Hooke
using evidence of cork to name “cells” etc
All drawings accurate detail. All incorrect parts identified and corrected.
