Funguslike Protists                                       PART 4






                            Fungi-like  protists  are  not  included  in  the  Fungi  kingdom  (mushrooms)

                   because their body structure and reproduction method is different from the Fungi
                   group. For example, slime molds which are members of Protists are similar to fungi in
                   that  they  have  a  cell  membrane  structure  similar  to  that  of  Algae,  while  their

                      reproduction is similar to that of fungi. Meanwhile, the movement in the vegetative
                   phase is similar to that of Amoeba.

                                                              Fungi-like protists are not included in the
                     Mushroom-like Protists             Fungi kingdom (mushrooms) because their body
                     Fungal-like  protists  that  have   structure and reproduction method is different
                     the following characteristics.     from the Fungi group. For example, slime molds
                     1. Are eukaryotic.                 which  are  members  of  Protists  are  similar  to

                     2. Does not have chlorophyll.      fungi  in  that  they  have  a  cell  membrane
                     3. Can produce spores.             structure  similar  to  that  of  Algae,  while  their
                     4. Are heterotrophs.               reproduction  is  similar  to  that  of  fungi.
                                                        Meanwhile,  the  movement  in  the  vegetative
                                                        phase is similar to that of Amoeba.




                         As  you  can  imagine,  funguslike  protists  are  protists  that  have  some
                    characteristics of fungi. Fungi and slime molds use spores to reproduce. Slime molds,
                    like fungi, feed on decaying organic matter and absorb nutrients through their cell

                    walls. However, fungi and slime mold differ in the composition of their cell walls. Fungi
                    cell walls are composed of a substance called chitin. Chitin is a complex carbohydrate
                    that is found in the cell walls of fungi, and in the external skeletons of insects, crabs,
                    and centipedes. The cell walls of funguslike protists do not contain chitin as a true
                    fungus  does.  The  cell  walls  of  these  protists  contain  cellulose  or  celluloselike
                    compounds. Slime molds are found in a variety of colors, ranging from yellows and
                    oranges to blue, black, and red as shown in Figure 4.1 They usually are found in damp,
                    shady places where decaying organic matter is located, such as on a pile of decaying
                    leaves or on rotting logs. Slime molds are divided into two groups—acellular slime
                    molds and cellular slime molds.
