Lesson 5: Homeostasis and Cell Processes-pages 50-61
 SHORT ANSWER: Know the four things that cells need to maintain homeostasis:
obtain and use energy, make new cells, exchange materials, and eliminate wastes
 Know that cells in multicellular organisms work together to maintain homeostasis for the
entire organism.
 SHORT ANSWER: Know the main transport system in the human body is the
cardiovascular system and be able to explain this system works.
o Cardiovascular system includes the heart, blood vessels, and blood.
o The heart pumps the blood through branched blood vessels that come close to
every cell in the body.
o Red blood cells carry materials (oxygen) to the cells and carry wastes (carbon
dioxide) away from the cells.
 SHORT ANSWER: Know the two types of vascular systems in many plants.
o Xylem-the tissue that transports water from and materials from the roots to the
rest of the plant
o Phloem-the tissue that transports food made within plant cells.
 Be able to explain the processes of photosynthesis and cellular respiration.
 Know that producers (plants, algae, and some bacteria) make their own food through
photosynthesis.
 Be able to tell how cells exchange materials.
o Passive Transport: diffusion, osmosis-hypertonic, hypotonic, isotonic
o Active Transport: endocytosis; exocytosis
 SHORT ANSWER: Explain how organisms maintain homeostasis:
o Cells obtain energy, divide, and transport materials
o Multicellular organisms: cells must work together to maintain homeostasis for the
whole organism
 When an organism is cold-cells respond in order to maintain internal
temp. Muscles cells contract to generate heat
 Reptiles-bask in the sun or hide in the shade to maintain internal temp.
 Some animals hibernate when temps. become extremely cold
 Trees lose leaves-this reduces water loss for the plant during winter
months
Terms to know: homeostasis, photosynthesis, cellular respiration, passive transport, active
transport, diffusion, osmosis, endocytosis, exocytosis, unicellular organism, multicellular
organism, xylem, phloem
Human Body Systems Text: Lessons 2, 3, and 4-pages 14-43.
Be familiar with the skeletal system, muscular system, circulatory system (cardiovascular
system and lymphatic system), digestive system, and excretory system.
Be able to identify the parts of each system and diseases or injuries to the system.
This will be multiple choice format on the test.
