What is the nematodes common, unscientific name?
Roundworms
Nematodes are said to have three primary blank layers: the
ectoderm, mesoderm and endoderm.
Germ
Nematodes are bilaterally blank, which means the body is the same
on both sides.
Symmetric
Nematodes are the opposite of segmented worms. What is this
called?
Unsegmented
Nematodes do not have respiratory systems; instead they absorb
oxygen through their skin in a process known as blank.
Diffusion
How do nematodes control movement?
Hydrostatic skeletal system
Roundworms have a blank digestive system.
Complete
Food processing occurs within the alimentary blank which runs
lengthwise along the body.
Canal
The blank consists of three parts, the “mouth and lips, buccal cavity
and pharynx.
Stomodeum
The blank functions by digesting, absorbing water and nutrients, and
eliminating the residues of digestion.
Intestine
The blank serves as the anus and is where waste is excreted.
Proctodeum
The nematode blank system consists of a set of neuronal processes
that run lengthwise on the nematode body.
Nervous
Neuronal processes consist of neurons that have a cell body also
known as a blank.
Neurocyte
What are a group of neurocytes called?
Ganglion
What is connected to the ganglion and surrounds the esophagus
(pharynx)?
Nerve ring
Which is the smaller of the two, male nematodes or female
nematodes?
Male
What is the scientific term for mating in nematodes?
Copulation
During copulation, what type of sperm crawls along the spicule?
Amoeboid
Eggs may be embyonated or blank, which means that they may not
yet be developed.
Unembryonated
What is the flexible outer covering which acts as an exoskeleton
called?
Cuticle
The cuticle allows the nematode to maintain internal blank.
Stability
The cuticle is formed by secretion of what?
Hypodermis
As a blank, the cuticle provides protection.
Barrier
As a blank, the cuticle detects changes in the environment.
Sensory array
As a blank, the cuticle acts as an antagonist to longitudinal muscles.
Hydrostatic skeleton
There are two types of species of nematodes, free-living species and
blank species. Parasitic
What kind of free-living nematodes have a large position in
decomposition, and recycling? These nematodes are also extremely
sensitive to pollution.
Marine Nematodes
Parasitic nematodes live off of blank organisms, such as plants and
animals.
Living
The organisms parasitic nematodes live off of are known as what?
Hosts
Where are the parasitic nematodes of the fig wasp discussed in the
Power Point found? Panama Canal
The parasitic nematodes of the fig wasps penetrate the blank of the
female wasp and slowly consume her.
Body cavity
Nematodes are the most abundant blank organisms.
Multicellular
In what process can some nematodes alter their metabolism to
survive extreme conditions?
Cryptobiosis
What is the scientific name of the largest nematode ever recorded?
Placentonema gigantissima
How long was the largest nematode ever recorded?
Over 27 feet
Typically one handful of soil contains how many roundworms?
Thousands
Nematodes can be found in places with extreme environments like
Antarctica and blank.
Oceanic trenches
What animal was Placentonema gigantissima found in?
Sperm whale
How small can nematodes get?
0.01 inches
Nematodes are said to be blank, which means their bodies consist of
three primary germ layers.
Triploblastic
