BIO ABC1

Biosphere

all of the environments on Earth that support life

Ecosystem

all the living and nonliving things in particular areas

tropical, grasslands, deserts & coral reefs

Communities

All the organisms in a particular ecosystem (meadow)

plants, animals, mushrooms, fungi

Species

a group whose membranes can only reproduce w/ other membranes of the group.

Population

same species living in an given area

Organisms

an individual living thing (humans, plants, animals, fungi)

all the organisms in your campus make up a community

Organ system

organs that work together to perform particular functions

Organ

body of structure of several tissues

Tissues

a group pf similar cells with a specific function

Cells

a living unit, separated from its environment by a membrane

Organelle

a membrane bound functional compound of a cell

Molecules

a cluster of atoms held together by bonds

Energy flow through ecosystem

Light energy comes from the sun - plants convert sunlight to chemical energy - organisms use chem. energy to do work - chemicals in plants are passed to organisms that eat plants.

RECYCLES

Eukayotic cells

cells that contain several membrane - enclosed organelles such as the DNA, nucleus, mitochondria, and chloroplasts LARGER

can be found in fungi kingdom

prokaryotic cell

A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles; found only in the domains Bacteria and Archaea. SMALL

Eukayotic cells & Prokaryotic cells have...?

both use an external membrane to regulate the passage of materials from & to surroundings

Charels Darwin

a man who developed the theory of evolution by natural selection

synthesized his theory from all the listed observations and interference

Natural selection

A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.

Experimental group

the group in an experiment that receives the variable being tested

control group

the group that does not receive the experimental treatment.

Quantitative

Data that is in numbers

Qualitative

Data in the form of words

Controlled experiment

tests experimental and control groups in parallel

control of an experiment

the control group is matched with the experimental group except for one of the experimental variable
