Fill in the blank

100

200

Sponges reproduce _____ through _____.

asexually, fragmentation

300

Animal cells group together to make more _____ systems.

complex

400

Polyps and medusae have _____ and a _____ cavity.

500

multicellular, eukaryotic 

Definitions

100

Cnidoblasts 

Cells that have rolled-up flagella that extend and inject a paralyzing liquid into their prey.

200

Pores

Holes that allow water to flow through them.

300

Porocytes

Cells that form the pores which let water flow into the sponge. 

400

Bilateral symmetry

A body that can be divided into two equal parts using an imaginary line. 

500

Sessile

Animals that are fixed to the seabed and don´t move (like corals.)

Compare/contrast

100

Internal vs. external skeletons 

An internal skeleton provides the animal´s shape and supports muscle movement, an external skeleton protects the animal.

200

Bilateral vs. radial symmetry

Bilateral means the body can be divided into two parts while radial means the body has several planes of symmetry. 

300

Spicules vs. spongin (parts of the porifera.)

Both make up the internal skeleton that protects the porifera. Spicules are rigid spines while spongin are flexible fibres. 

400

Polyps vs. medusae

Both body types of cnidarians, polyps are sessile and sac-shaped while medusae are umbrella-shaped. Polyps normally reproduce asexually while medusae mostly reproduce sexually. 

500

The sexual phase of medusae vs. the asexual phase of polyps. 

Medusae form obules and sperm and release them into the aquatic environment during the sexual phase. Then a zygote forms after fertilization which then develops into a polyp. 

During their asexual phase polyps produce buds, small parts that break off and can develop into a new medusa. 

Examples

400

Name as many animals that are cnidarians as you can.

Jellyfish, hydras, anemones, corals. 

500

Name as many parts of the Porifera as you can. 

Osculum, central cavity, choanocytes, porocytes, pinacocytes, spicule, spongin. 

Name that thing

100

Cells on the sponge´s external layer. 

Pinacocytes.

200

Large hole in the porifera used to release water and waste substances. 

Osculum

300

Another word for this animal is sea sponge. 

Porifera

400

Cells that cover the inner cavity and create a stream of water as well as filter food. 

Choanocytes

500

This is a characteristic of animals that means they stop growing once they reach adulthood. 

Limited growth
