algae
eukaryotic, photosynthetic living organism, ranging from single-celled organisms to giant kelps
Antony van Leeuwenhoek
Dutch scientists(1632-1723), developed simple microscope, discovered details of cells of animals, bacteria, and blood
Aristotle
Greek philosopher(384-322BC), who developed an early system of classification for plants and animals based on form and structure
bacilli
rod-shaped, spore forming, backteria, often occurs in chains or pairs
bacteria
microscopic, single-cell, prokaryotic, spherical, spiral, or rod-shaped organisms
basidiomycota
division of higher fungi that bear spores from small, club-shape cells called basidia. Includes mushrooms, puffballs, toadstools
blue-green algae
called cyanobacteria, photosynthetic, single-cell, prokaryotic organisms
cavity slide
microscope slide that has a depression in the center used to keep a liquid in place
cell
microscopic organisms or smallest unit of an organism that can function alone or with other cells to produce life functions
characteristic
distinct feature that helps to identify a living thing or object
chloroplast
green, grainy pigment in plant cells, uses light energy to tear apart water molecules, beginning photosynthesis
chloroplast
organelle in plant cell that contains chlorophyll and absorbs sunlight
class
a group of siilar living things
classification
systematic grouping of living things into categories based on structural or evolutionary relationships
clip
microscope part connected to stage, holds slide in place
cocci
spherical bacteria
colony
group of same-species organisms living together
compound microscope
having more than one lens
conclusion
end result found by experiment
constants
all factors which remain the same for each trial of IV
consumer
organisms that cannot produce own food, so ingests its food
control
standard of comparison in experiment
convex
having surface that curves outward
cover slip
small plastic (or glass) that covers specimen
cyanobacteria
mainly aquatic, photosynthetic bacteria
decomposer
organisms that breaks down dead plants or animals, releasing nutrients for use in ecosystem; mainly bacteria and fungi
dependent variable
what is measured or counted, or observed objectively
domain
recent classification system, highest level above kingdom level
Domain Archaea
different from all other known bacteria, live in extreme conditions unsuitable to other bacteria
Domain Bacteria
unicellular, prokaryotic microorganisms
Domain Eukaryota
includes all eukaryotic organism classifications
electron microscope
scope that uses electrons instead of light
eukaryote
cell or organism with nucleus and membrane-bound organelles
eyepiece
lens nearest the eye in a microscope
filament
long, thin serires of cells attahed to each other at their ends, for example algae
flagellum
tail-like structure
form
shape of an organism
fungus
eukaryotic organisms that lacks chlorophyll and vascular tissue
heterotroph
an organism that cannot make its own food
hypothesis
prediction about outcome of experiment. Usually If...then...statement.
independent variable
variable you manipulate
Kingdom Fungi
kingdom containing all organisms described as being eukaryotic, lacking photosynthetic ability, digest and then absorb nutrients
Kingdom Monera
kingdom containing all organisms that are prokaryotic, some photosynthetic, some consumers
lens
shaped piece of glass used to focus light rays to form an image
lens field
area included within the image seen through a lens
lichen
composite organisms of fungi and green algae
magnify
to enlarge objects
magnification
ratio the size of an object's image to the object
micro
prefix meaning small
microorganism
small, living thin
moneran

multicellular
consisting of more than one cell
nonvascular
without vessels to carry nutrients and water through organism, no true roots or stems or leaves
nucleus
part of cells that contains genetic material and responsible for cell growth and reproduction
observation
use of all the senses to gain scientific information
organelle
small organs within a cell that perform life processes
photosynthesis
process by which carbohydrates are made from carbon dioxide and water using light energy and releasing oxygen as a byproduct
producer
photosynthetic plant or bacterium, forming first level of the food chain
prokaryote
cell or organisms lacking a distinct nucleus or other organelles
protoctist
any unicellular eukaryotic organisms, protozoans, slime molds, and algae
Robert Hooke
English scientist (1635-1703), developed compound microscope, wrote Micrographia, coined term cells
species
lowest level of classification, most specific classification
specimen
something being observed with a microscope
spirilla

stage
microscope platform that holds slide
structure
arrangement of parts of an organism
taxonomy
