Name, draw & describe the O2 carriers. Name, draw & describe the sensory messengers. Name, draw & describe the cells that are supporters. Red blood cells, doughnutshaped with no nucleus Nerve cells, long, branchlike shape carrying electrical signals. Bone cells, star-shaped, rigid to give the body shape. Name, draw & describe the cells that contract & relax. Name & describe the outer cells that cover and protect. Name & describe the cells that continue the species. Blood Muscle cells, long and elastic to allow stretching & rebounding. Skin (epithelial) cells are constantly being replaced. Describe & give an example of a prokaryotic cell. Has no definite nucleus DNA floats freely in the cytoplasm Small Simple Describe & give an example of a eukaryotic cell. Has a defined nucleus containing DNA Large Complex Bacteria are prokaryotic cells. Plant & animal cells are eukaryotic Egg & sperms cells (gametes) combine during reproduction to form a new organism (zygote) Name the largest human cell Egg cells produced by the female are the largest human cells.

Name & spell correctly the part which builds protein Name & spell correctly the part which transports proteins to wherever they are needed Cell membrane Ribosomes Endoplasmic reticulum Name & spell correctly the part which checks, sorts, & packages proteins for transport Name & spell correctly the part which is a gel-like fluid that sorrounds all the cell parts Name & spell correctly the part which combines sugar molecules with O2 to produce energy. Golgi apparatus Cytoplasm Mitochondria Name & spell correctly the part which contains all the information for working, growing, & dividing. Name & spell correctly the part which traps light energy & converts it into sugar molecules. Name & spell correctly the part which recycles old cell materials for re-use. Nucleus Chloroplast Lysosome How long does it take the human body to replace brain cells? Once brain cells die, new ones are not created. Drugs and alcohol destroy brain cells which can never be replaced. How many seconds does it take for a red blood cell to circulate throughout the whole body? About how many days does it take humans to shed & re-grow outer skin cells? 20 seconds 27 days If your cells were placed end to end, how many times would they stretch around the Earth? What human cell is about the diameter of a human hair? How many kilometers of nerve cells run throughout our bodies? 47 times Egg cell 63 kilometers How fast do messages travel through the nerve cells as electrical impulses? How many cells in your body will have died & been replaced while you are reading this card? How many cells are in 4 square centimeters of skin? 400 kilometers per hour 50 million 3 million The City Limits are to a town as the _________ _____________ is to a cell. The principal is to a school as the ___________ is to a cell. The generators which run machinery are to a fatory as the _________________ is to a cell.
