nonvascular, plant-like organisms that lack chlorophyll and depend upon other organisms for food
fungi
true or false: fungi are considered autotrophs
false; they are heterotrophs (depend on others for food)
The threadlike structures, or filaments, that form the body of a fungus
hyphae
scientists who study fungi
mycologists
true or false: most fungi are saprophytes
true (saprophytes obtain their nutrition from dead organisms)
fungi with club-shaped structures for spores
club fungi
visible part of the fungi
fruiting body
part of the mushrooms and toadstools that releases spores
gills
type of fungi that lacks gills
shelf fungi (bracket fungi)
an organism that lives on or in another living organism and derives its nutrition from that organism
parasite
true or false: rusts are parasites and heteroecious
true (they have two hosts)
fungi that produce black spores
smuts
how many types of mold are there?
three (cheese, bread, and parasitic)
examples of sac fungi
yeasts and mildews
jelly-like organisms often seen on the bark of fallen trees
slime molds
relationship between an alga and a fungus
lichen
two different kinds of organisms living together for mutual benefit
symbiosis (lichens practice this)

- cranial cavity
- spinal cavity
- thoracic cavity
- abdominopelvic cavity
soft internal organs
viscera
cells form __1__, which form __2__, which form __3__
- tissues
- organs
- systems
function together to bring food, water, and oxygen to the cells and to carry away waste products
cardiovascular system
the body’s defense against disease-causing organisms and other foreign invaders
immune system
supply the body tissues with oxygen and remove carbon dioxide
respiratory system
breaks down food into a form that can be absorbed by the bloodstream
digestive system
removes waste from the body
excretory system
coordinates the activities of the body
nervous system
coordinates the body through chemicals and chemical messengers called hormones
endocrine system
skin
integumentary system
support and structure of the body
skeletal system
moves the body
muscular system
responsible for the continuation of the human race
reproductive system
stable internal environment
homeostasis
maintain homeostasis
feedback mechanisms
moves the body and all its parts
muscle tissue
controls organs and coordinates all of their functions
nerve tissue
tissue that lines vital body parts
epithelial tissue
tissue that connects parts of the body
connective tissue
thin, flexible sheets of tissue that cover or line a part of the body
membranes
nonliving material surrounding cells
matrix
true or false: there are vestigial organs in the human body
false; every organ is important in some way
