Cell Organelles

PARTS OF A CELL Plasma (cell) membrane Cell Wall Cytoplasm Nucleus Nuclear membrane Ribosomes Endoplasmic Reticulum Golgi Apparatus Mitochondria Lysosome Vacuole Chloroplasts

Plasma Membrane

The Plasma Membrane is like the SKIN of the cell. The Cell Membrane controls what enters and leaves the cell. . Copyright © Arizona Board of Regents http://www.biology.arizona.edu

Nucleus

The Nucleus is like the BRAIN of the cell. The nucleus is the control center of the cell. It contains the genetic information for the cell in the form of DNA called chromatin. It is a membrane bound structure usually found in the middle of the cell.

The Mighty Mitochondria

The “Mighty” Mitochondria is the POWERHOUSE of the cell. Mitochondria - Makes energy in the form of ATP ATP are produced to “power” the cell.

Endoplasmic Reticulum

The Endoplasmic Reticulum is the cells DELIVERY SYSTEM. Endoplasmic Reticulum (ER) - Delivers proteins. A membranous tubular system throughout the cell connecting the nuclear membrane to the cell membrane.

Golgi Apparatus

The Golgi Apparatus is the PACKAGING CENTER of the cell. Golgi Apparatus - Packages and modifies proteins.

Vacuoles

Vacuoles are the STORAGE SPACES for cells. These are membranous sacs that can store food, enzymes, wastes, and other materials needed by the cell. Plant cells have large vacuoles for water storage.                                                                                            Copyright  Tupperware Worldwide www.order.tupperware.com

Lysosomes Specialized vacuole that contains digestive enzymes.

Ribosomes Protein synthesis (makes proteins)

Cytoplasm Jello-like substance where organelles are embedded.

Centrioles

Centrioles Centrioles help in cell division. They are found only in animal cells.

Cell Wall

The Cell Wall is like a suit of ARMOR around the cell. Cell Wall - Supports the cell. It is found in plant cells NOT animal cells.

Chloroplast

Chloroplasts are where PHOTOSYNTHESIS occurs. Contain chlorophyll, a green pigment that traps the energy from light. Found in plant cells and some protists, NOT found in animal cells.

Differences in Plant Cells & Animal Cells

Plant Cells have a cell wall large vacuoles for water storage chloroplasts for photosynthesis

Centrioles for cell division Animal Cells Vacuoles are smaller Centrioles for cell division

DIVISION OF LABOR Many celled organisms are called MULTI-CELLULAR. One cell within an organism may be adapted for movement, while another cell carries out digestion. Cell specialization allow the individual cells to depend on each other rather than trying to carry out all life functions (division of labor).

LEVELS OF ORGANIZATION Multi-cellular organisms are made up of cells, tissues, organs, and then, organ systems. Ex. Bone cell, bone tissue, the bone is an organ, all the bones form the skeletal system which is a part of the 13 systems that make up a human.

CELL TRANSPORT PASSIVE TRANSPORT DO NOT REQUIRE ENERGY FROM THE CELL. ACTIVE TRANSPORT REQUIRES ENERGY BY THE CELL.

PASSIVE TRANSPORT DIFFUSION The movement of particles from an area of high concentration to a low concentration. OSMOSIS The diffusion of WATER molecules. Example of Diffusion: coffee aroma

ACTIVE TRANSPORT Substances move from an area of low concentration to an area of high concentration. Transport of materials against a “concentration gradient” requires energy.
