Q

What does bilateral symmetry mean? Use an example of an organism

A

Symmetry about a line has definite left and right side and only a longitudinal line would cut the animal in half e.g. lobster

Q

What does radial symmetry mean? Use an example of an organism

A

Symmetry about a point, two identical half’s are formed no matter how the animal is cut longitudinally e.g. coral

17
Q

Which is associated with evolved animals radial or bilateral symmetry?

A

Bilateral symmetry

18
Q

What are spicules in relation to sponges ?

A

Make up a type of internal skeleton

19
Q

What are gemmules in relation to sponges?

A

Groups of sponges that can later germinate into new sponges

20
Q

Describe the structure and function of nematocysts in jellyfish

A

Nematocysts are coiled tube threads that might bear barbs and are often poisoned. They drive their threads with barbs with poison into the victim or prey and cause rapid increase in hydrostatic pressure.

21
Q

What are 4 ways members of phylum Platyhelminthes are adapted to parasitic mode of living?

A

Most have suckers for attachment to the host
Have very tough tegument that prevents digestion by host enzymes
Some lack a digestive system and simply absorb nutrients directly from the host
Most of the body is taken up by reproductive system

22
Q

What is coelom?

A

A cavity within the mesoderm

23
Q

Why was the development of coelom important in the evolution of animals ?

A

It allowed the organs of early coelomate animals the potential to increase in size and activity.

24
Q

What does autotroph mean?

A

Organisms that can produce their own food

25
Q

What does heterotroph mean?

A

Organism that can’t produce its own food

26
Q

What does chemotroph mean?

A

Organism that obtains energy by oxidation of electron donors in their environment

27
Q

What does phototroph mean?

A

Organisms that use light energy for certain metabolic functions

28
Q

What does hermaphrodite (monoecious) mean?

A

Has male and female parts

29
Q

What does dioecious mean ?

A

Has either male or female parts not both

30
Q

What does polymorphism mean?

A

Several different forms of the same species

31
Q

What does sessile mean?

A

Fixed to the one place, immobile

32
Q

What does diploblastic mean?

A

Two cell layers and no coelom

33
Q

What does triploblastic mean?

A

Three cell layers and no coelom

34
Q

What does exoparasite mean?

A

Lives on the outer surface of the host

35
Q

What does endoparasite mean?

A

Parasite that lives inside its host

36
Q

What does acoelomate mean?

A

Organism with no body cavity

37
Q

What does pseudocoelomate mean?

A

An organism with a false body cavity

38
Q

What does coelomate mean?

A

Organism with a true body cavity
