Study Notes
Cells
- All organisms have cells that specialize.
- Cells are categorized into two groups: prokaryotes and eukaryotes.
Prokaryotic Cells
- Prokaryotic cells are simpler than eukaryotic cells.
- Prokaryotic cells are single-celled organisms.
- Prokaryotic cells lack organelles and a nucleus.
- Prokaryotes belong to the kingdom Monera.
- Examples include bacteria.
- Genetic material (DNA) is free in the cytoplasm.
Eukaryotic Cells
- Eukaryotic cells are more complex.
- Eukaryotic cells contain both a nucleus and organelles.
- Eukaryotic cells belong to the kingdoms Animalia, Plantae, Fungi, and Protista.
- Eukaryotic cells keep genetic material inside the nucleus.
- Most eukaryotes are multicellular.
Plant Cells
- Plant cells use chloroplasts to photosynthesize.
- Plant cells have cell walls for support.
- Many plant cells store nutrients in large vacuoles.
Fungal Cells
- Fungi, unlike plants, lack chloroplasts, preventing photosynthesis.
- Fungi absorb nutrients from the environment.
- Fungi typically do not have large vacuoles filled with liquid.
Protist Cells
- Protists are a diverse group of mostly unicellular organisms.
- Some protists are photosynthetic.
- Some protists consume other organisms.
- Protists can cause diseases.
- Their shape and structure are adapted to their environment and food sources.
Animal Cells
- Animal cells are multicellular.
- Animal cells communicate and work together.
- Animal cells have different sizes and shapes depending on their function.
- Animal cells contain a nucleus and organelles, though they lack chloroplasts and cell walls.
