Biology 11 - Classification

What are the 7 characteristics of living things?

1. Living things are made of cells

2. Living things reproduce

3. Living things grow and develop

4. Living things use materials and energy

5. Living things respond to the environment

6. Living things are homeostatic

7. Living things change and adapt over time to their environment

What is homeostasis?

Process where organisms maintain a stable internal environment for survival

Eg. Shivering when cold; sweating when hot.

Explain why things are organized or divided into different levels in the body?

The body has different functions within

What are the different levels of organization?

Subatomic particles, atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, biome, biosphere.

What is symbiosis?

Interaction between two different species that live closely together

What are the 3 types of symbiotic relationships?

1. Commensalism

2. Mutualism

3. Parasitism

What is Commensalism?

+/o relationship

One species benefits and the other species is unaffected - it is neither helped or harmed

What is mutualism?

+/+ relationship

Both species benefit or depend on the symbiotic relationship to survive

What is parasitism?

+/- Relationship

a symbiont (known as the parasite) benefits from the symbiotic relationship but the host is harmed by it.

Ex. Lice and human

What are the three domains?

Bacteria, Archaea, and Eukarya

What is autotrophic?

The ability to obtain food on it’s own (photosynthesize)

What is heterotrophic?

When an organism must obtain food from others

What are the six kingdoms?

1. Kingdom eubacteria

2. Kingdom Archaebacteria

3. Kingdom Protista

4. Kingdom fungi

5. Kingdom plantae

6. Kingdom Animalia

Kingdom Eubacteria

Prokaryotic (no nucleus)

Unicellular (Single-celled)

Cell Wall: Yes

Autotropic or heterotopic
