- Differences in traits among individuals of a species
- Behavior
- Ways in which living things respond to stimuli
- Enviornment
- Everything that surrounds a living thing
- Homeostasis
- Ability of a living thing to keep conditions within it's body constant
- Response
- An organism's reaction to change
- Stimulus
- Something that causes a reaction to take place
- Carrying Capacity
- Largest ammount of a popultion that can be supported in an area
- Ecology
- Study of living things and their enviornments
- Habitat
- Place where an organism lives
- Niche
- An organisms role in it's enviornment
- consumer
- Organism that obtains food by eating other organisms
- Ecosystem
- All the living and nonliving things and the enviornment
- Interaction
- An organism's impact on it's enviornment
- Producer
- Organism that makes it's own food
- Decomposer
- Organism that breaks down the waste remains of other organisms
- Limiting Factors
- Conditions in an enviornment that limit where an organism can survive
- Scavenger
- An organism which feeds off the remains of dead organisms
- 2 facts about a Deciduous Forrest
- Moderate climate, various animals and birds live here and a Deciduous forrest has a long growing season followed by a cold winter
- 2 facts about a Desert
- Temperatures range from moderate to hot and there is very little rain, lizards and animals who are adapted to these conditions live here

- Moderate climate, large herds of animals and various shrubs and grasses live here
- 2 facts about a Taiga
- A moist subarctic coniferous forest that begins where the tundra ends and is dominated by spruces and firs
- 2 facts about Tropical rain forrests
- Large ammouns or rain, Tall trees grow here
- 2 fats about Tundra
- Mosses and small shrubs grow here, ground is permanently frozen
- Name the three parts of the cell theory
-
1) All living things are made up of one or more cells
2) Cells are the basic unit of structure and function in living things
3)Cells are created by other living cells - Chloroplast
- Organelle of green plant cells where photosynthesis occurs
- Nucleus
- The ''control center'' of the cell
- Osmosis
- Movement of water through a membrane
- Vacuole
- Liquid filled spaces in a cell's cytoplasm
- Cell
- Basic unit of structure and functon in living things
- Cell wall
- Outer, nonliving part of a PLANT cell
- Cytoplasm
- All the living material inside a cell except the nucleus
- Mitochandria
- Rice shaped structures that produce a cell's energy
- Organelles
- small structures in a cell's cytoplasm tha carry out specific jobs
- Ribosomes
- Small, round structures that produce protein in a cell
- Cell membrane
- Thin structure that surrounds a cell
- Diffusion
- Movement of material from an area where molecules are crowded to a less crowded area
- Mitosis
- Divisoin of the nucleus
- Organ
- Group of tissues that work together to preform a certain job
- Tissue
- Group of cells that work together to preform a specific job
- Who was ''Brown''
- A scientist who invented the compound microscope
- Who was ''Hooke''?
- First scientist to observe cells
- Who was Schwann?
- Scientist who proved that cells are the basic unit of structure in living things

- Invented the second classification which is still used today: included bacteria, protists, fungi and Monerans
- What is a control?
- Part of an experiment which is not changed
- What is a variable?
- Part of an experiment which is changed
- Adaptation
- Trait of an organism which helps it live in it's enviornment
- Budding
- Asexual reproduction in which a new organism is formed from a ''bud'' on the parent
- Fission
- Asexual reproduction in which a single parent splits in half to form a new organism
- Migration
- Movement of organisms from one habitat to another
- Succession
- Gradual change in an organism that occurs when it's enviornment is changed
- Asexual Reproduction-Reproduction requiring only one parent
- Reoproduction requiring only one parent
- What topics would a biologist study?
- Living things such as animals, plants, bacteria, fungi and protests
