Circulatory and Respiratory System
100
List all the parts of the animal cell and plant cell.
Animal cell: Cell membrane, cytoplasm, vacuole, ribosomes, mitochondria, and nucleus. Plant cell: Cell wall, cell membrane, cytoplasm, vacuole, ribosomes, mitochondria, chloroplasts adn nucleus.
100
What are the organs of plants?
Stems, roots, leaves & flowers.
100
What is the function of chlorophyll?
Chlorophyll is a green substance that traps energy from the Sun and allows plants to make thier own food.
100
What parts make up the circulatory system and what is its job?
The circulatory system is made up of the heart, blood and blood vessels. To carry food and oxygen to each cell and take away cell's waste.
200
What are the three important characteristics of cells?
Size, shape and special structures in contains.
200
Many plants use a system of tubes to transport materials such as water and minerals. What is the tube system called.
Vascular system

Why can't animals make their own food? (Hint:What do plants have that animals do not?)
Animal cells do not contain chloroplasts with chlorophyll.
200
Why are many parts of your respiratory system covered with mucus?
The mucus traps dust and germs in the air.
300
List the terms organ, cells, organ system and tissue in order from largest and most complex to smallest and simplest.
Organ system, organ, tissue and cells.
300
What are the functions of a plant's stem?
1. The stem provides support for leaves., flowers and fruit. 2. The stem carries water, minerals and sugar between the roots and the leaves.
300
*Bonus*Plants make a sugar, glucose, in a process called photosysnthesis. Explain photosysnthesis.
During photosysnthesis, plants use light energy from sunlight, carbon dioxide from the air, and water to make sugar and oxygen.
400
List an organ system and describe its job.
-The digestive system takes in food and breaks it down into forms the body can use. -The circulatory system transports nutrients and oxygen to cells and carries away wastes. -Respiratory system takes in oxygen and helps remove carbon dioxide. -Excretory system removes wastes from the body.

What are the functions of xylem tubes and phloem tubes?
Xylem tissue carries water and minerals from the roots to the rest of the plant. Phloem tissue carries sugar from the leaves to other plant parts.
400
Define the process by which cells break down sugar to release energy.
Cellular respiration: plants and animals must break down food to release the stored energy. *Bonus* Where in the cell, does sugar begin to break down through a series of reactions?
500
What are the four functions of cells?
1. Cells take in food and get rid of waste. 2. Cells use materials in food to grow & repair wounds. 3. Cells sense & respond to changes in their surroundings. 4. Cells communicate & work together with other cells.
500
What are the three functions of roots?
1. Roots anchor a plant in soil. 2. Roots may store food. 3. Roots absorb water and minerals needed by the plant from the soil.
500
How do humans get rid of carbon dioxide?
They breathe carbon dioxide out of their lungs.
500
*Bonu* What is the order of structures that oxygen passes through between your nose and bloodstream?
Nose or mouth, sinus, trachea, larynx, bronchi, bronchioles, air sac and bloodstream.
