Kingdom Animalia. Bellringer 3/22/11Copy questions and answer on page Which of these organisms do you think are animals? 2. On what characteristics.
Invertebrates By Alenna Naeve A.N. Arthropods/Arachnids Definition : An animal that has a jointed exoskeleton. Body systems: They breathe through organs.
Kingdom Animalia. ~ Characteristics ~ Multicellular Multicellular Eukaryotic with no cell walls Eukaryotic with no cell walls Heterotrophs (consumers)
Definition: A type of animal that filters the water it lives in to get food. Body Systems: Their symmetry is asymmetrical and they don’t have any body.
Algae – The Plant-like Protists. Plant-like Protists Contain chlorophyll located in chloroplasts. Most make their own food through photosynthesis. Many.
INVERTEBRATES About 97 percent of all animals are invertebrates.
