Study Notes
Cell Types
- Prokaryotic and eukaryotic cells represent two primary cell types on Earth.
- Prokaryotes are always unicellular organisms, while eukaryotic cells can be unicellular or multicellular.
Eukaryotic Cells
- Eukaryotic cells are present in all living organisms made of more than one cell, including animals, plants, fungi, and protists.
- Eukaryotic cells are characterized by membrane-bound organelles such as a nucleus and mitochondria.
Animal Cells
- Fundamental units of all animals, including birds, fish, reptiles, mammals, and amphibians.
- Contain membrane-bound organelles: nucleus, mitochondria, Golgi apparatus, and endoplasmic reticulum.
- Surrounded by a plasma membrane.
Plant Cells
- Building blocks of plants, characterized by features common to eukaryotic cells.
- Possess a cell wall, which is absent in animal cells, providing structure and support.
- Contains organelles such as chloroplasts for photosynthesis.
Fungi Cells
- Cells contain structures and organelles found in both plant and animal cells.
- Lack the ability to perform photosynthesis.
- Have a cell wall primarily composed of chitin, a polysaccharide distinct from the cellulose found in plant cell walls.
Protist Cells
- Possess all membrane-bound organelles found in animal cells, with some types containing chloroplasts for photosynthesis.
Prokaryotic Cells
- Smaller and simpler than eukaryotic cells, lacking membrane-bound organelles.
- Always unicellular and categorized as either bacteria or archaea.
- The basic structural features of bacteria and archaea are similar, but they have different compositions and characteristics.
Bacteria Cells
- Unicellular prokaryotic organisms without membrane-bound organelles.
- Do not contain a nucleus, mitochondria, endoplasmic reticulum, or Golgi apparatus.
Archaea Cells
- Unicellular prokaryotes sharing several structural similarities with bacteria.
- Differ in biochemical and genetic composition from bacteria despite superficial similarities.
