Big Ideas in Life Science Ms. Moye
Big Ideas • Biologists investigate an incredible range of questions. • But underlying all of their work are certain big ideas or concepts. • These big ideas connect the study of living things.
The big Ideas include the following: • Organisms are diverse, yet share similar characteristics • Groups of organisms change over time • The structure and function of organisms are complementary • Organisms operate on the same physical principles as the rest of the natural world
Diverse but Similar • Although living things vary greatly, they have many basic similarities • All organisms are made up of tiny building blocks called cells • Every living thing is mainly made up of water • All organisms contain DNA • All living things require energy
Similarities • They grow or become larger. • Development is the process of change that causes an organism to become more complex during its lifetime • All living things reproduce to produce more of their own kind.
Evolution • The characteristics (way that someone or something looks and is identified by) of any group of organisms change. • It is different from growth and development since it occurs over many generations
Complementary Structure and Function • Structure is the way an organism is put together as a whole • Functions enable an organism to survive • The structure and function of organisms are complementary or work together to meet its needs
Physical Principals • Life follows the same rules or principals as the rest of the natural world • Systems are the same for all organisms. Heredity, chemical processes (photosynthesis, and digestion of food)
Notes • Life Science is also known as? • What is Life Science? • Biology • The study of living things.
List the four branches of life science and explain each. • Molecular Biology is the study of chemical building blocks of cells; Genetics is the study of how information about organisms is passed from parent to offspring, Physiology is the study of structure and functions of organisms, and ecology is the study of how organisms interact with their surroundings.
How is development different from growth? • Development causes an organism to become more complex with age or a lifetime. Growth is the process by which an organism becomes larger.
What are four big ideas in Life Science? • Four big ideas are that organisms are diverse, yet share similar characteristics, group of organisms change over time, the structure and function of organisms are complementary, organisms operate in the same physical principal as the rest of the world.
What are some ways that a cat and a tree are similar, and different? • Both are made of cells and have similar chemical compositions, reproduce, grow, develop, and need energy. They differ in that a car is an animal with fur that can move from place to place. It gets its energy from eating food; a tree makes its own food
What are functions? • What does the statement; living things are diverse but similar mean? • Processes that allow an organism to survive. • The statement “Living things are diverse, but similar” means that although there is a great variety of living things, they share many basic characteristics, such as being composed of cells, and being made up of mostly water.
Explain the principle that structure and function are complementary in living things. • Structure is the term that describes how living things are put together. Function is the term that refers to all the processes that keep a living thing alive. In living things, the structures and functions are complementary, which means they work together to meet the needs of organisms.
