General Characteristics of Phylum Porifera
An example is the sponge...
1..It's common name is the " pore-bearing " animal.
2..The body develops from two (2) cell layers
3..It is asymmetrical
4..It's a free-living organism
5..Body is covered with pores
6..They are sessile
7..They have special cells for digestion and support.
8..They are the simplest of all animals.
9..Reproduction is both a-sexual and sexual.
10..They are filter feeders
11..Digestion is intracellular
12..structural elements are spicules and spongin
Arthropoda (Arthon- Jointed; podos- legs)
1..Arthropoda, animals having jointed appendages or legs.
2..It is a phylum of triploblastic, haemocoelomic, segmented invertebrates having head, thorax and abdomen, a chitinous exoskeleton and jointed legs and appendages.
3..Most successful phylum on the 4..Earth that has ever existed.
5..Arthropods were first studied by Aristotle.
6..Von Siebold coined the term Arthropoda
