Activity! Collect the cell function card sort activity and correctly match the structure with the function! Once you have finished copy the cell function table into your jotter!

Stains Stains are used to view cells under a microscope so that we can see the cell structures more clearly To view cheek cells, we use methylene blue To view onion cells, we use iodine solution Clearly / iodine solution / methylene blue / Structures

Field oF view The diagram below shows some animal cells under the microscope. Lets work it out! Count the cells in the field of view Divide the ‘field of view’ length by the number of cells. Remember to add in units! Field of view = 150 units Calculate the average diameter of one animal cell.

Cells Quiz! 2. Which part of the cell controls the activities inside the cell? A. Cytoplasm B. Nucleus C. Cell membrane D. Cell wall

Cells Quiz! 3. Which part of a plant cell contains chlorophyll? A. The nucleus B. The cell membrane C. The cytoplasm D. The chloroplasts

Cells Quiz! 4. Cellulose is a strong substance found in all plant cells. Which part of a plant cell contains cellulose?   A. The cell membrane B. The cell wall C. The chloroplasts D. The vacuoles

Cells Quiz! 5. What is the function of the cell membrane? A. To control which substances move in and out of the cell B. To help the cell to keep a firm shape C. To make food for the cell D. All of the above
