  3. Prokaryotic cell Prokaryotic cells do not have a nucleus or any other membrane-bound organelles , so their genetic information is kept in a circular loop called a plasmid. Some examples of prokatyoric cells are those in the monera kingdom such as bacteria and cyanobacteria.

  4. Parts of a Prokaryotic cell

  5. Eukaryotic cell • Eukaryotic cells contain complex structures enclosed within membranes. They have a nucleus where the DNA is carried. There are three main types of eukaryotic cells: plant cells, animal cells and fungal cells.

  6. Plant Cell Plant cells differ from other eukaryotic cells by: • A large central vacuole (controls movement of molecules) • A cell wall (containing cellulose, hemicelluloses and pectin) • A chloroplasts that contain chlorophyll ( the pigment that gives plants their green color and allows them to do photosynthesis)

  7. Animal cell • Animal cells are different from other eukaryotes because they don’t have cell walls either chloroplasts, and they have smaller vacuoles. The lack of cell wall is what allows this kind of cells to adopt different shapes.

  8. Fungal cell Fungal cells differ from other eukaryotes by: • They have a cell wall (containing chitin). • There is less definition between cells; some of them have porous partitions called septa • Some of them haven’t got flagella.

  9. Important scientists related to the cell • Robert Hooke was an English scientist who discovered the cell and proposed the Cell Theory in the 17th century. His theory says that new cells are formed from other existing cells, and that the cell is a fundamental unit of structure, function and organization in all living organisms.

  10. Antonie van Leeuwenhoekwas a Dutch tradesman and scientist. He is commonly known as "the Father of Microbiology. He also discovered bacteria, spermatozoa and blood flow in capillaries.
