Biology II: 1.1-1.3 Study Guide

Question 1

How do you define structure?

Answer 1

How something is made.

Question 2

How do you define function?

Answer 2

How something works.

Question 3

Why does structure determine function?

Answer 3

The way an object is made determines what it can be used to do. In other words, the structure determines the function.

Question 4

What happens to the function when the structure of an object is changed?

Answer 4

The function is changed, too.

Question 5

What does the structure of an object include?

Answer 5

The materials, parts, shape, etc.

Question 6

What is the function of a Ziploc bag and how does its structure allow it to do that function?

Answer 6

The function of a Ziploc bag is to hold foods, materials, anything that can fit inside of it. The structure allows it to do that because the plastic holds what’s inside, and the zipper zips it so nothing can fall out of the bag.

Question 7

What is PMC?

Answer 7

Program, Metabolism, and Container.

Question 8

What are program, metabolism, and container?

Answer 8

Program: The instructions written in DNA, reproduction, and growth of organisms.

Metabolism: The energy and organism takes and uses, chemical reactions.

Container: Cell, let’s things in and out, barrier.

Question 9

What are a few characteristics of living things?

Answer 9

Grows, has cells, reproduces, has metabolism, etc.

Question 10

What is the abbreviation that means program, metabolism, and container and is important to all life?

Answer 10

PMC.

Question 11

How do the characteristics of living and non-living things determine if they are living or non-living?

Answer 11

Living things must be able to grow, reproduce, and have the important PMC of life. They also must have cells, organs, tissues, etc. Non-living things don’t have cells, metabolism, the PMC of life, organs, tissues, etc. Non-living things are also unable to grow, reproduce, and do what a living thing can.

Question 12

What does it mean to be living?

Answer 12

It means to be able to reproduce and grow as an individual.

Question 13

List all of the levels of organization by smallest to largest and give an example for each one.

Answer 13

• Atom: Carbon.
• Molecule: Carbon dioxide.
• Organelle: Chloroplast.
• Cell: White blood cell.
• Tissue: Muscle.
• Organ: Heart.
• Organ System: Circulatory system.
• Organism: Cardinal.
• Population: White tail deer in Tippecanoe County.
• Community: All living things in Tippecanoe County.
• Ecosystem: Tropical Rainforest.
• Biome: Tundra.
• Biosphere: Earth.

Question 14

Define organism, population, community, ecosystem, and organ.

Answer 14

• Organism: A living individual, both multicellular and singlecellular.
• Population: Members of the same species in the same area.
• Community: Different populations/species in the same area.
• Ecosystem: All of the living and non-living things.
• Organ: Different tissues that perform a similar function.

Question 15

Define atom, tissue, organelle, biome, molecule.

Answer 15

• Atom: The building block of a chemical element.
• Tissue: Different cells working on the same task.
• Organelle: Specialized structure that performs various jobs inside cells.
• Biome: Similar ecosystems around the planet.
• Molecule: Multiple atoms bonded together.

Question 16

Define biosphere, organ system, and cell.

Answer 16

• Biosphere: Ecosystems make up the planet.
• Organ system: A group of organs interacting to perform a similar function.
• Cell: Small unit capable of carrying out all life processes.

Question 17

Define the Levels of Organization.

Answer 17

The levels of smallest to biggest of the important parts of life and its surroundings.

Question 18

How do the parts of an organism connect to help it survive, and why are its surroundings important?

Answer 18

The parts of an organism interact together and have certain jobs to help an organism survive, reproduce, and grow. An organism’s surroundings are important to it because of the circle of life and their needs. The biosphere and ecosystem contain the materials, such as water and prey, needed to help the organism survive. A community, population, and biome help it to survive by providing it with the necessary temperatures and environment, the right to reproduce, and the right the co-exist with other organisms and thrive.
