invertebrate

Question 1

Porifera

Answer 1

Sponges are animals of the phylum Porifera. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells

Question 2

Cnidaria

Answer 2

Cnidaria is a phylum containing over 10,000 species of animals found exclusively in aquatic environments: they are predominantly marine species. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey

Question 3

Annelida

Answer 3

The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches

Question 4

Hydroid

Answer 4

is a field-proven technology leader in advanced marine robotics specifically, Autonomous Underwater Vehicles

Question 5

Jellyfish

Answer 5

Jellyfish or jellies are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles

Question 6

Platyhelminthes

Answer 6

The flatworms, or Plainclothesmen, are a phylum of relatively simple bilateral, unsegmented, soft-bodied invertebrates.

Question 7

Nematoda

Answer 7

The nematodes or roundworms constitute the phylum Nematode. They are a diverse animal phylum inhabiting a very broad range of environments

Question 8

Pinworms

Answer 8

The pinworm, also known as threadworm or seatworm, is a parasitic worm. It is a nematode and a common intestinal parasite or helminth, especially in humans

Question 9

Tapeworms

Answer 9

Ancestor is a class of parasitic flatworms, of the phylum Plainclothesmen. Biologists informally refer to them as Modesto. The best-known species are commonly called tapeworms.

Question 10

Bivalves

Answer 10

The Bivalvia, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, comprise a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts

Question 11

Cephalopods

Answer 11

A cephalic is any member of the molluscan class Cellophane. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles modified from the primitive molluscan foot.

Question 12

Gastropods

Answer 12

The Gastropods or gastropods, more commonly known as snails and slugs, are a large taxonomic class within the phylum Molluscan. The class Gastropods includes snails and slugs of all kinds and all sizes from microscopic to large.

Question 13

Coelomate

Answer 13

have a fluid filled body cavity called a compel a complete lining called peritoneum derived from mesosphere

Question 14

Acoelomate

Answer 14

an invertebrate lacking a compel, especially one belonging to the group comprising the flatworms and anemometers and characterized by bilateral symmetry and a digestive cavity that is the only internal cavity.

Question 15

Radial Symmetry

Answer 15

arrangement of parts of an organism around a single main axis, so that the organism can be divided into similar halves by any plane that contains the main axis. The body plans of echinoderms, phosphorescent, cnidarians, and many sponges and sea anemones show radial symmetry. Compare bilateral symmetry.

Question 16

Asymmetry

Answer 16

lack of equality or equivalence between parts or aspects of something; lack of symmetry.

Question 17

Bilateral Symmetry

Answer 17

arrangement of an organism or part of an organism along a central axis, so that the organism or part can be divided into two equal halves. Bilateral symmetry is a characteristic of animals that are capable of moving freely through their environments. Compare radial symmetry.

Question 18

Tentacle

Answer 18

a slender flexible limb or appendage in an animal, especially around the mouth of an invertebrate, used for grasping, moving about, or bearing sense organs.

Question 19

Cnidocyte

Answer 19

A cnidocyte is an explosive cell containing one giant secretory organelle or cnidarian that defines the phylum Cnidarian. Cnidarian are used for prey capture and defense from predators.

Question 20

Ectoderm

Answer 20

is one of the three primary germ layers in the very early embryo. The other two layers are the mesosphere and mender, with the echinoderm as the most exterior layer. It emerges and originates from the outer layer of germ cells.

Question 21

Endoderm

Answer 21

the innermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the lining of the gut and associated structures.

Question 22

Ovary

Answer 22

a female reproductive organ in which ova or eggs are produced, present in humans and other vertebrates as a pair.

Question 23

Teste

Answer 23

Male organ that produces sperm
