Basic Cell Type- EukaryotesContain an NUCLEUS. Include plants, animals, fungi, and protists. Cell size is about 10 times compared to average cell. Proteins are more complexed with DNA into multiple chromosomes. In cell division their micro-tubules pull chromosomes to opposite poles during cell division process, called mitosis. Flagella are complex structures that whip back and forth, rather than rotating. Basic Cell Type- ProkaryotesNo Nucleus. Basically single-celled . Bacteria Shapes...

Phylum Porifera (sponges) multicellular organisms without tissues, organs, or body cavity Heterotroph organism that obtains energy from the foods it consumes; also called a consumer Spicules hard spear or star-shaped structures; made of CaCO3 (limestone) or silica (glass) Choanocyte line the gastrovascular cavity & capture food Amoebocyte digest & distribute food Osculum large opening at the top where excess water leaves Spongocoel large central cavity of the sponge
