Final Flashcards
Saprodes
Organism that obtains food from decaying organic matter
Protist
Any organism that is not a plant, an animal, a fungus, or a prokaryote
Mycelium
Many hyphae tangled together into a thick mass; comprises the bodies of multicellular fungi
Pseudopods
Temporary projections of cytoplasm used by some protist for feeding or movement
Food vacuole
A small cavity in the cytoplasm that temporarily stores food
Contractile vacuole
Cavities in the cytoplasm that are specialized to collect water
Hyphae
Water molds that produce thin filaments
Medusa
Motile stage of the life cycle of cnidarian that has a bell shaped body
Fungi
Kingdom composed of heterotrophs; many obtain energy and nutrients from dead organic matter
Polyp
Usually sessile stage of the life cycle of a cnidarian that has a cylindrical body with arm like tentacles
Sporozoans
Do not move on their own and are parasitic
Pellicle
Cell membrane in euglenas
Eyespot
Group of cells that can detect changes in the amount of light in the environment
Phytoplankton
Population of algae and other small, photosynthetic organisms found near the surface of the ocean and forming part of plankton
Zooplankton
Tiny animals that form part of the plankton
Rhodophyta
Red algae
Phaeophyta

Mycology
The study of fungi
Ganglia
Groups of nerve cells found in the head of flatworms
Cephalization
Rhizoids
And fungi, a robot-like hypha that penetrates the surface of an object; in mosses, a long thin cell that anchors the moss to the ground and absorbs water and minerals from the surrounding soil
Invertebrate
Animal that does not have a backbone, or vertebral column
Vertebrate
Animal that has a vertebral column or backbone
Zygote
Fertilize eggs
Blastula
Hollow ball of cells when a zygote undergoes a series of divisions
Bilateral symmetry
Body plan in which only a single imaginary line can divide the body into two equal halves characteristic or worms arthropods and chordates
Radial symmetry
Body plan in which body part repeat around the center of the body; characteristic of sea anemones and sea stars
Cephalization
Concentration of sense organs and nerve cells at the front of an animal’s body
Hermaphrodite
Individual that has both male and female reproductive organs
