1. The heart keeps blood moving throughout your body.
2. Sugar is an energy rich substance made by plants that is used as a source of energy for cells.
3. Scientists classify leaves by color, blade shape, venation (veins), and leaf margins.
4. Water and minerals get to each cell in a plant through the xylem tubes.
5. Sap is the excess of sugar made in the leaves.
6. Plants need sap because it is the food used by all the plant cells that do not make their own food.
7. Know the purpose of the following organs and tissues in the body:
· Capillary-reaches every cell in the body
· Small intestine-passes nutrients from digested food into the blood
· Kidney- filters waste products from the blood
· Artery-carries blood from the heart to the body
· Lung- exchanges gases with the atmosphere
· Blood-carries oxygen, food, and nutrients through vessels
· Heart-pumps blood throughout the body
· Stomach-breaks down food with digestive juices and muscles
8. For plants to make their own food, CO2 (carbon dioxide), water (H20) and light must be present.
9. Be able to label a diagram of the circulatory system parts: lungs, veins, arteries, capillaries, & heart.
10. The body’s cells get all the things they need to survive when the capillaries carry blood rich with oxygen, food, and other nutrients to every cell and then carry all waste materials away.
11. The following foods contain sugar: apples, regular (not diet) soda, raisins, and frosted cereal.
12. The purpose of the kidneys is to filter waste from the blood.
13. Cellular respiration is the process where plant cells break down sugar.
14. Cellular respiration is the name of the process where animal cells break down sugar.
15. How do we “consume” solar energy? Plants must have sunlight to produce their own food/sugar. Animals eat plants and use the food the plants made.
16. The circulatory system in animals is similar to the vascular system in plants.
17. The first step of digestion occurs in the mouth. This is where food is broken into smaller pieces and mixed with saliva.
