THE CELLScienceIndicator 1Boston International School

Objective: To recognize living things and their main features, to value the importance of our bodies.

Learning objective: Identify the importance of the cell and the function of its parts.

Biblical Principle:So God created man in his own image, in the image of God created he him; male and female created he them.

The Cell All living things are made up of cells. Cells are the smallest working units of all living things. All cells come from preexisting cells through cell division.

Cell PartsOrganelles

Surrounding the Cell

Cell MembraneOuter membrane of cell that controls movement in and out of the cellDouble layer http://library.thinkquest.org/12413/structures.html

Cell WallMost commonly found in plant cells & bacteriaSupports & protects cells

http://library.thinkquest.org/12413/structures.html

Inside the Cell

Nucleus Directs cell activitiesSeparated from cytoplasm by nuclear membraneContains genetic material - DNA

Nuclear MembraneSurrounds nucleusMade of two layersOpenings allow material to enter and leave nucleus http://library.thinkquest.org/12413/structures.html

ChromosomesIn nucleusMade of DNAContain instructions for traits & characteristics

http://library.thinkquest.org/12413/structures.html

NucleolusInside nucleusContains RNA to build proteins http://library.thinkquest.org/12413/structures.html

CytoplasmGel-like mixtureSurrounded by cell membraneContains hereditary material

Endoplasmic ReticulumMoves materials around in cellSmooth type: lacks ribosomesRough type (pictured): ribosomes embedded in surface http://library.thinkquest.org/12413/structures.html

RibosomesEach cell contains thousandsMake proteinsFound on ribosomes & floating throughout the cellhttp://library.thinkquest.org/12413/structures.html

MitochondriaProduces energy through chemical reactions breaking down fats & carbohydratesControls level of water and other materials in cellRecycles and decomposes proteins, fats, and carbohydrateshttp://library.thinkquest.org/12413/structures.html

Golgi BodiesProcess proteins for secretion.

http://library.thinkquest.org/12413/structures.html

LysosomeDigestive 'plant' for proteins, fats, and carbohydratesTransports undigested material to cell membrane for removalCell breaks down if lysosome explodes http://library.thinkquest.org/12413/structures.html

VacuolesMembrane-bound sacs for storage, digestion, and waste removalContains water solutionHelp plants maintain shape.

ChloroplastUsually found in plant cellsContains green chlorophyllWhere photosynthesis takes placehttp://library.thinkquest.org/12413/structures.html

TOPIC: TISSUES CELLTISSUE ORGAN SYSTEM

Cells, Tissues, Organs, and SystemsA cell is the smallest unit of living matter; the building blocks of living things.Tissues are groups of cells working together to perform a certain job.Organs are groups of tissues that perform a certain function.Organs working together to carry out a certain life function are an organ system.
