Study Notes
Cell Theory
- States that all living things are composed of cells.
- Cells arise from preexisting cells.
- Cells perform essential functions necessary for life.
Tissues
- Defined as a group of similar cells working collaboratively.
- Function together to carry out specific tasks in an organism.
Organs
- Composed of multiple tissue types working in unison.
- Each organ has a specialized role contributing to the organism's overall function.
Organelles
- Membrane-bound structures found in eukaryotic cells.
- Perform specialized functions vital for cell operation (e.g., energy production, waste processing).
Cell Membrane
- Encloses all types of cells.
- Regulates the movement of substances in and out of the cell.
Cell Wall
- Present in certain cells, offering a rigid structure.
- Provides protection and support, commonly found in plant cells and some bacteria.
Capsule
- A protective, slimy layer surrounding some bacteria.
- Shields bacteria from harmful substances and helps retain moisture.
Cytoplasm
- The jelly-like substance within a cell, exclusive of the nucleus.
- Contains organelles and is the site for many cellular processes.
Flagellum
- A whip-like appendage allowing some cells to move in their environment.
- Facilitates mobility in certain bacteria and single-celled organisms.
DNA
- Contains genetic information essential for protein synthesis.
- Plays a crucial role in regulating various cellular functions.
Chromosome
- Consists of tightly coiled DNA within the cell.
- Carries the genetic blueprint necessary for inheritance and cellular activities.
