Study Notes
- A cell constitutes the smallest unit in living beings.
- Cells are too small for naked eye observation.
- Cells exhibit varied shapes.
- All cells have an external envelope and an aqueous interior housing various organelles.
- Cells execute nutrition, relationship, and reproduction.
- Nutrition transforms substances into energy.
- Relationship involves interacting with environmental stimuli.
- Reproduction directs growth and division.
- Living organisms are either unicellular or pluricellular, based on cell number.
- Unicellular organisms consist of a single cell, like bacteria.
- Pluricellular organisms consist of numerous cells, examples include trees, animals, and humans.
- Cells are classified as prokaryotic or eukaryotic based on their structure.
- Prokaryotic cells feature DNA dispersed in the cytoplasm, lacking a nucleus; bacteria exemplify this type.
- Eukaryotic cells contain a nucleus, bounded by a membrane, that houses DNA, which carries genetic material.
- Eukaryotic cells include vegetal and animal types.
