Cell Parts and Functions Table Essay
Parts and Functions Table| Cell Organelle| Cell Function| Nucleus| Directs all cell activities “Brain or Control Center of cell”| Nuclear Envelope (Membrane)| Controls what passes in and out of the nucleus| Cytoplasm| Jelly-like substance found inside cell that acts as a medium for chemical reactions within the cell| Golgi Body (Apparatus)| Packages the proteins made by the ribosomes so they can be sent out of the cell.
The UPS store of the cell| Mitochondrion| “powerhouse of the cell” breaks down sugar molecules to release energy, site of cellular respiration, double membrane, self-replicating, contains own DNA, cristae| Vacuole| “Storage tanks” Can hold food, water or waste for the cell| Ribosome| Makes proteins for the cell, can be found attached to the endoplasmic reticulum or free in the cytoplasm| Endoplasmic Reticulum (ER)| Transportation network for the cell, moves materials around in the cellRough Endoplasmic Reticulum (RER)- endoplasmic reticulum that has ribosomes attached.
Smooth Endoplasmic Reticulum (SER)- does not have ribosomes attached| Lysosome| “Stomach of the cell” Helps the cell digest food, waste and worn out cell parts| Nucleolus| Produces ribosomes and rRNA( stuff ribosomes are made of)| Cell Membrane (plasma membrane)| “Gatekeeper” Separates the cell from the rest of the environment and helps control what passes in and out of the cell.
Semi-permeable: allows some materials to pass through but not all| Chloroplast| A special plastid that contains chlorophyll a pigment that captures the sun’s energy to produce glucose in a process called photosynthesis| Cell Wall| Rigid outer layer made of cellulose that supports and protects the cell (plant, fungi, and bacterial cells)| Vesicle| Stores and Transports substances from the Golgi Body to the cell membrane for export. The UPS truck of the cell”| Cytoskeleton| gives support and shape to the cell, made of proteins| Centriole| Organizes special parts of the cytoskeleton called microtubules for cell division, migrates to opposite ends (poles) of the cell to assist with cell division|
