Study Notes
Introduction to Cells
- All living organisms are composed of cells, which classify into two main categories: prokaryotic and eukaryotic cells.
- Organisms can be unicellular (made of one cell) or multicellular (made of multiple cells).
Prokaryotic Cells
- Prokaryotic cells are unicellular microorganisms.
- They lack a distinct nucleus and membrane-bound organelles.
- Prokaryotic cells are simple, small, and primarily consist of bacteria.
- DNA in prokaryotes is free-floating within the cell.
- Reproduction in prokaryotes is asexual, resulting in exact copies or clones.
Eukaryotic Cells
- Eukaryotic cells can be unicellular or multicellular.
- They have a nucleus and membrane-bound organelles, making them larger and more complex.
- Examples of eukaryotic organisms include animals, plants, fungi, and protists.
- Each organelle within a eukaryotic cell has specific functions that help maintain homeostasis.
- Eukaryotes can reproduce asexually (clones) or sexually (producing variations).
Comparison of Prokaryotic and Eukaryotic Cells
- Prokaryotes are smaller than eukaryotes.
- Prokaryotes lack a nucleus, while eukaryotes possess one.
- Organelles in prokaryotic cells lack membranes, whereas eukaryotic organelles are membrane-bound.
- Prokaryotic DNA is free-floating compared to eukaryotic DNA, which is located in the nucleus.
- Prokaryotic reproduction is entirely asexual, while eukaryotes can reproduce by both asexual and sexual means.
Performance Assignment
