Study Notes
Unicellular Organisms
- Bacteria and protozoans are unicellular.
Prokaryotic Cells
- Bacteria are not eukaryotic.
- Bacterial genetic material is located in the nucleoid.
- Cytoplasmic streaming is a system of fibers within a bacterium to move substances.
- Ribosomes read RNA and assemble amino acids into proteins
Cell Structures
- Chromatin: DNA, RNA, and proteins in the nucleus.
- Optimal Temperature Range: A species of bacteria grows best between 16-20°C.
- Isotonic Solution: Solutions containing equal amounts of solute, maintaining cell balance.
- Active Transport: Requires energy to move substances across the cell membrane.
- **Cell Theory:**Explains how cells work. It is false that cells in a colony can't live independently.
- Eukaryotic and prokaryotic cells share organelles (true).
- Photosynthesis: Happens in chloroplasts' grana (true).
- Lipid Bilayer: The hydrophobic portion of the lipid bilayer is region 'a' in the diagram.
- Diffusion and Osmosis: Different terms, but the same process; their definitions are false (Diffusion and osmosis are not the same process, they are both forms of passive transport).
- Semipermeable Membrane: Allows particle movement, in both directions (true).
- Passive Transport: Cannot move particles from low to high concentration areas (false).
- Spontaneous Generation: Life arises from non-living things (incorrect model).
- Cell Theory: All living things are made of cells (correct model).
- Preformation Model: Eggs and sperm contain miniature people.
- Unicellular Organisms: Organisms consisting of a single cell.
- Capsule: A slimy coating surrounding the cell wall of a bacterium.
- Plastids: These include chloroplasts and leucoplasts.
- Turgor Pressure: Maintained by central vacuoles, providing cell rigidity.
- Rough Endoplasmic Reticulum: Studded with ribosomes.
- Nuclei: Found only in eukaryotic cells.
- Lysosomes: Vacuoles with digestive enzymes.
- Golgi Apparatus: Receives substances from the endoplasmic reticulum and packages them.
- Cell Structures (List): Endoplasmic reticulum, mitochondrion, Golgi apparatus, cilium, nucleus, cell membrane, chromatin, nucleolus
- Plant Cell-Specific Structures: Cell wall, central vacuole, and chloroplasts.
