Absence of organelles. There is no true nucleus. Some bacteria have flagellum.

Ultrastructure of E. coli Draw and label a diagram of the ultrastructure of Escherichia coli (E. coli) as an example of a prokaryote

What are the functions of these prokaryotic cell parts? Annotate the diagram from with the functions of each named structure

2.2.3 Identify structures from in electron micrographs of E. coli

Prokaryotic cells divide by binary fission Asexual method of reproduction. The cells produced are genetically identical (clones) State that prokaryotic cells divide by binary fission

2.3.1.Draw and label a diagram of the ultrastructure of a liver cell as an example of an animal cell

2.3.2 Annotate the diagram from with the functions of each named structure.

Identify structures from in electron micrographs of liver cells.

Which structures can you identify in this false- coloured TEM (transmission electron microscopy) image?

2.3.3 Identify structures from in electron micrographs of liver cells.

Magnification x47,500 at 10X8 cm size.

Magnification x47,500 at 10X8 cm size. Nucleus Nuclear membrane mitochondria endoplasmic reticulum (ER) ribosomes Identify structures from in electron micrographs of liver cells.

What are the differences between prokaryotic and eukaryotic cells? Comparison of prokaryotic and eukaryotic cells Comparison of prokaryotic and eukaryotic cells

1 Differences between plant and animal cells fixed and rather regular shape Can change shape, usually rounded State three differences between plant and animal cells

Extracellular matrix: refers to components outside the cell. PLANT CELLS Prevents excessive uptake of water by the cell ANIMAL CELLS Support: Provides structural support for the integrity of the tissue or organ. extracellular matrix protein (fibronectin, green) cytoskeletal microfilaments (actin, red) Outline two roles of extracellular components
