Cells
Every living organism is composed of cells.
Cell Structure/Function
Nucleus: the command center of the cell
Nuclear Pores: pores on the nuclear envelope that contains protein and allows transportation in and out of the nuclear membrane
Chromatin: Contains proteins and DNA
Nucleolus: produces ribosomes and contains RNA (genetic information)
Nuclear Envelope: double membrane that contains the nucleus
Centriole: microtubules shaped like a cylinder that help make spindle fibers for cell division
Intermediate Filaments: protein fibers that makes the shape stable
Plasma Membrane: allows what enters and exits the cell, semi-permeable membrane
Golgi Apparatus/Complex: receives, packages, and secrets proteins
Vesicle: stores and transports materials
Mitochondria: produces ATP, carries out cellular respiration, powehouse of the cell
Ribosome: protein synthesis
Smooth Endoplasmic Reticulum: does not contain ribosomes, synthesizes lipid molecues
Microtubules: transports organelles, responsible for movement of the cell, participates in cell division (mitotic spindle)
Lysosome: digestion machines in the cell
Rough Endoplasmic Reticulum: contains ribosomes and synthesizes proteins
Cytoplasm: substance inside the cell but outside of the nucleus that contains the organelles
Flagellum: responsible for locomotion of the cell, whip-like appendage
Vacuole: stores water, food, and waste in plant cells
Cell Wall: only in plant cells, protects the cell
The nucleus, Endoplasmic Reticulum, and Golgi Apparatus all work together to maintain the cell's life. These three organelles help the mitosis and meiosis processes. The nucleus contains chromatin, which contains DNA. This DNA is then transcribed to RNA. The nucleolus produces ribosomes and contains RNA (genetic information). These ribosomes produce proteins by translating the RNA and transfers it to the Golgi Apparatus from the Endoplasmic Reticulum.
