3C Types of Cells Section 3C

Objectives I will be able to differentiate between eukaryotic cells and prokaryotic cells. I will be able to give examples of eukaryotic organisms and prokaryotic organisms.

Cell Types With more advanced microscopes, scientists discovered that all cells can be grouped into one of two major categories: prokaryotic cells eukaryotic cells

Cell Types - Prokaryotes Most prokaryotic cells are unicellular organisms called prokaryotes.

Cell Types - Prokaryotes The genetic material in a prokaryotic cell is not surrounded by a membrane.

Cell Types – Prokaryotic Cells Bacteria cells No nuclear membrane Contain only organelles that are not surrounded by a membrane (ribosomes)

Cell Types - Eukaryotes Plants, animals, fungi, and protists are all made of eukaryotic cells and are called eukaryotes. In eukaryotic cells, the genetic material is surrounded by a membrane.

Cell Types - Eukaryotes Every eukaryotic cell has membrane-surrounded organelles, which have specialized functions and enable the cell to carry out different functions at the same time.

Cell Types - Eukaryotes The nucleus is the part of a eukaryotic cell that directs cell activities and contains genetic information stored in DNA.

Diversity Among Eukaryotes Eukaryotic cells have much variety Cilia and flagella Chloroplasts Vacuoles Cell walls

Irreducible Complexity The parts of a cell are so dependent on one another that if just one part does not work right, the entire cell would most likely die.

Irreducible Complexity The cell cannot be reduced to something less complex and still function properly. Irreducible complexity points to a Designer of the cell and of the universe.
