a cool group of eukaryotes that cannot be classified as animals‚ plants‚ or fungi. Organisms in the Protista kingdom include amoebae‚ euglena and slime molds. Protist move throuout the slime molds and other things and reproduce with bacteria and fungi. Three types of fungus like protists cellular slime molds acellular slime molds Water molds Fungi Fungi are a group of organisms that were once considered a part of the plant kingdom. Now some scientists think that fungi are neither

They have cell walls made of carbohydrates. Cellular slime molds – phylum Acrasiomycota - move through soil and digest bacteria - during environmental stress they gather together forming multicellular colonies called slugs

1. Name and describe the life cycle of plants. The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2. Contrast the life cycle of plants to that of animals: Typical life cycle: alteration of generation (plants)‚ diploid (animals) Resulting structure from meiosis: spores-plants‚ gametes-animals Occurrence of mitosis: gamete production-plants‚ zygote to individual-animals 3.
