- chloroplast
- cell organelles that capture light energy and converts it to chemical energy. Heart of the generator
- vacuole
- Membrane-bound compartments. For temporary storage of materials. Plant cell.
- chromatin
- When a cell divides, the chromatin condenses to form chromosomes. Master set of directions for making proteins is contained here.
- flagella
- long projections that move with a whip like motion. In unicellular they are major means of locomotion and feeding.
- chlorophyll
- Green pigment. Traps light energy and gives leaves and stems their green color. Plant cell only.
- cytoskeleton
- Network of tiny rods and fillaments. Framework for a cell, supports the structure.
- golgi apparatus
- Flattened stack of tubular membranes that modifies the proteins. Modifies the proteins, sorts protein into packages for membrane-bound structures.
- cell wall
- A non-living section of the cell membrane, composed of celluse. Provides protection from physical injury, with vacuole, provides skelatal support. Plant Cell
- cell membrane
- composed of proteins and lipid molecules. Acts as a boundary layer to contain the cytoplasm. It interlocks cells together. It selects chemicals that can pass in and out of cells.
- nuclear envelope
- A double layer membrane covering the nucleus. It enclosed the contents of nucleus during most of the cells lifestyle.
- ribosome
- non-membrane spherical composed of RNA and protein. Used in protein synthesis.
- lysosome
- Are organelles that contain digestive enzymes. Digest excess or worn out organelles, food particles, engulfed viruses or bacteria. Animal cell
- endoplasmic reticulum
- Organell in euxariatic cell with a series of highly folded membranes surrounded in cytoplasm, rough have ribosomes. Is the site of cellular chemical reactions.
- nucleolus
- Large spherical domain for nucleous. Ribosomal RNA's are synthesized
- plastid
- Used for storage. Named according to the color of their pigment. Plant cell only.
- mitochondria
- Membrane bound organelles. Transform energy for the cell.
- micorfilament
- Solid protein fibers. Help maintain the shape of the cell.
- phospholipid
- Eukariotic membrane, highly folded, inner membrane. Bound organells that transform energy stored in food molecules it produces energy. Plant cell.
- microtubule
- thin hollow cylinders made of protein. Helps maintain the shape of the cell
- nucleus
- Responsible for cell division. Controls cellular functions.
- cilia
- Short, numerous projections that look like hairs. Help in locomotion and feeding.
