Study Notes
Cell Basics
- Cells are the fundamental building blocks of all living organisms.
- They contain a nucleus and various organelles.
- Two main types of cells: plant cells and animal cells.
Plant Cells
- Characterized by a rigid cell wall which helps maintain structure.
- Contain chloroplasts, enabling photosynthesis for food production.
- Generally have a square shape and one large vacuole for storage.
Animal Cells
- Surrounded by a flexible cell membrane, lacking a cell wall.
- Capable of movement due to their structure.
- Typically round in shape and contain smaller vacuoles compared to plant cells.
Similarities Between Plant and Animal Cells
- Both types of cells contain a nucleus and organelles, facilitating vital cellular functions.
Cell Structures
- Cell Membrane: Outer layer of animal cells that regulates entry and exit of substances.
- Cell Wall: A sturdy layer found in plant cells, primarily composed of cellulose, providing support and shape.
- Chloroplasts: Organelles in plant cells responsible for photosynthesis, containing chlorophyll.
- Cytoplasm: A gel-like substance between the cell membrane and nucleus where chemical reactions occur.
- Lysosomes: Contain digestive enzymes to break down waste.
- Vacuoles: Storage sacs for food, waste, and water; larger in plant cells than in animal cells.
Cell Types
- Eukaryote: Cells with a nucleus and membrane-bound organelles; includes protists, fungi, plants, and animals.
- Prokaryote: Simple cells without a nucleus or membrane-bound organelles; predominantly unicellular and include bacteria and archaea.
Differences Between Prokaryotic and Eukaryotic Cells
- Prokaryotic cells are simpler, lack a nucleus, and have no membrane-bound organelles.
- Eukaryotic cells are more complex, with a defined nucleus and various organelles allowing specialized functions.
- Both cell types contain ribosomes and genetic material (DNA).
Genetic Material
- Prokaryotes possess a single circular strand of DNA.
- Eukaryotes have multiple straight strands of DNA contained within the nucleus.
Additional Notes
- Eukaryotic cells can be unicellular or multicellular.
- Prokaryotic organisms are the simplest cellular forms, primarily unicellular bacteria.
- Membrane-bound organelles are characteristic of eukaryotic cells, enabling compartmentalization of cellular processes.
