Cell Organelles And Their Functions 6q2c6z

Cell Organelles and their Functions By: Vince Jayson V. Yabo

What is a Cell?  Structural, functional and biological unit of all organisms  Membrane-bound structure containing biomolecules such as  Proteins,  Nucleotides, and  Polysaccharides

 Smallest unit of life that can replicate independently

What is a Cell Organelle?   a specialized part of a cell;   analogous to an organ;  "the first organelle to be identified was th e  nucleus"

Different Cell Organelles These are the different cell organelles:  Nucleus  Nucleolus  Mitochondria  Vacuole  Lysosome

Different Cell Organelles  Chloroplast  Rough Endoplasmic Reticulum  Smooth Endoplasmic Reticulum  Cytoplasm  Nuclear membrane

Different Cell Organelles  Cell membrane  Cell wall  Ribosomes  Golgi Apparatus  Peroxisomes

Nucleus  Control center of the cell  Contains the Cell’s Genetic Information in the form of genes  Control cell activities

Nucleolus  Takes up about 25% of the Nucleus volume  Rewrites the ribosomal RNA and combines it with proteins  Assembles ribosomes

Mitochondria  Production of energy by synthesis of ATP  Processing and storage of calcium ions  Apoptosis, the process of programmed cell death  Regulation of cellular metabolism  Synthesis of certain steroids

Vacuole  Can only be found in plant cells  Stores food, water and wastes  Regulates turgur pressure in the cell  Helps increase cell size during cell growth

Lysosome  Breaks down larger food molecule into smaller ones  Digests old cell parts  Main site for intracellular digestion  Enables cells to make use of the nutrients

Chloroplast  Uses the energy from the sun to make food for the plant  The main site for photosynthesis within plant cells

Rough Endoplasmic Reticulum  Responsible for assembly of proteins in the cell  Produces polypeptides and proteins

Smooth Endoplasmic Reticulum  Make cellular products like hormones and lipids

Cytoplasm  Jelly-like fluid that fills the cell  s/protects cell organelles  Holds cell organelle in place  Stores molecules for cellular processes

Nuclear Membrane  Controls movement of materials in/out of the nucleus  Surrounds the nucleus

Cell Membrane  and protection  Controls movement of materials in/out of the cell  Barrier between cell and its environment  Maintains homeostasis

Cell Wall  

 and protection for plant cells  Allows HO, CO and O to through in/out of the cell

Ribosome  Interprets cellular information from the nucleus  Synthesizes proteins

Golgi Apparatus  Modifies, sorts and packages proteins for secretion  Transports lipids around the cell  Involves in the creation of lysosomes

Peroxisomes  Breaks down very long chains of fatty acids in the cell
