HW: Mythbusters due by 9/19
Unit test 9/12
Body systems quiz 9/10
What are two types of cells? Prokaryotic – Simple cell, no nucleus or
membrane bound organelles. Ex. Bacteria
Eukaryotic- Complex cells, has a nucleus and membrane bound organelles. Ex. Animals, Plants, Fungus, Protist
11 main body systems Nervous system Endocrine system Integumentary system Muscular system Skeletal system
Urinary system Respiratory system Reproductive system Circulatory system Digestive system Lymphatic system
Homework Determine the function of each of the 11
human body systems. Identify at least two organs that are
involved with each system.
Two Types of Reproduction Sexual Reproduction
Two Parents Genetically diverse (different genes than
parents) Asexual Reproduction
One Parent Genetically identical (same genes as parent)
All Living Things Adjust to Their Surroundings. Homeostasis
Maintain internal control
Example: body temperature, glucose, water and pH levels in the blood are maintained at a constant rate.
Negative feedback loop Any change to a system causes the system
to return to its original state. Osmoregulation Thermoregulation Blood pH and Blood glucose levels
Positive feedback loop Amplifies a change in the system, causing
it to move farther and farther from its original state. Examples: childbirth and ripening fruit
Video explanation
All Living Things Grow and Develop. Growth
Increase in size
Development changes that happen as you grow To become more complex
All living things have complex chemistry Consists of complex molecules that go
through chemical changes to stay alive.
All Living Things Can convert energy to food. Or convert food to
energy. Main source of
energy for all living organisms is the SUNSUN
Producer: Producer: make their own food. Ex plants
Consumer: Must take in food to survive
All living things….. Respond to their environment Adaptation:
any alteration in the structure or function of an organism or any of its parts that results from natural selection and by which the organism becomes better fitted to survive and multiply in its environment.
Four unifying principles Cell theory
Cells are the basic unit of life All living things are made up of cells Cells come from other cells.
Four unifying principles Gene Theory
Genes determine the characteristics of living things.
They are located on chromosomes that are found in every cell.
Genes are passed on from parents to offspring.
Four Unifying principles Homeostasis
Keeping internal conditions constant even though the external environments change
Four Unifying Principles Evolution
Occurs by the process of natural selection. Organisms become more suited to their
environments through evolution because they develop adaptations.
