Cells are the basic building blocks of life.
All living things consist of at least one or more cells.

ORGANELLES - STRUCTURES
Organelles are “little organs” – structures with particular functions within cells
You need to know the function of the organelles and differences in what organelles there are in plant cells, animal cells, and unicellular orgs (e.g. Paramecium)
![Page 21: DO NOW!!](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816509550346895dd77c7e/html5/thumbnails/21.jpg)

Make a Cell
Plant cell we will make and copy into your notes
Copy animal cell into your notes and label
Leave two full pages in your notes for functions◦ Cell membrane, mitochondria, nucleus, endoplasmic reticulum (smooth
and rough), Golgi bodies, cytoplasm, chloroplasts, cell wall, vacuole, cilia, flagella, lysosomes, ribosomes, centrioles, contractile vacuoles, eyespot, anal pore, oral groove

To Do:
Using the handout from Mrs H you need to fill this out
In pairs or groups of three to speed the process up
Then copy into your books the graphic organiser from the next slide

Organelles
Organelles are “little organs” – structures with particular functions within cells
Organelles common to all eukaryotic cells:◦ Nucleus◦ Ribosomes◦ Cell membrane◦ Cytoplasm◦ Mitochondria
Use the text to find the functionof each of these organelles.
Include a sketch of the organelleto help you identify it later

MAH 2011
Nucleus
Contains genetic material
Controls the functioning of the cell
Has pores so that things can enter and exit
![Page 26: DO NOW!!](https://reader036.fdocuments.in/reader036/viewer/2022062410/56816509550346895dd77c7e/html5/thumbnails/26.jpg)

MAH 2011
Structure of plasma membranes
Contains lipids called phospholipids in two layers (a lipid bilayer)
Contains cholesterolContains integral membrane proteins:
◦ receptors for hormones◦ transport proteins (ion channels etc.)◦ structural proteins
Forms a semi-permeable barrier for the transport of materials due to the nature of the phospholipids in the membrane
