Warm-up activity! Name that symmetry!

Answer: Asymmetry! Sea sponge Asymmetry – non-symmetrical

Note: Terms in green are definitions – these are key terms to know Terms in blue are important words or concepts - please make note

Activity: Phylum Porifera Worksheet Directions: Once you have finished filling in the worksheet, begin colouring the sponge diagram according to the colour coding system listed on your Animalia Outline handout. Feeding (digestive system) = blue Respiration (respiratory system) = brown Internal transport (circulatory system) = red Excretion (excretory system) = green Response (nervous system) = orange Movement (musculoskeletal system) = grey Reproduction (reproductive system) = yellow
