Slime molds used to be classified as Fungi, but now are considered part of the Protista Kingdom. The mode of nutrition in plants can be autotrophic mode or heterotrophic mode. Mark ‘T’ if the statement is true and ‘F’ if it is false: Answer: (a) Carbon dioxide is released during photosynthesis. Most saprophytes do not directly digest dead matter: instead, they parasitize fungi that digest dead matter, or are mycorrhizal, ultimately obtaining photosynthate from a fungus that derived photosynthate from its host.

Plants like these use enzymes to convert organic food materials into simpler forms from which they can absorb nutrients (Figure 1b). They are saprophytic organisms which derive nutrition from dead and decaying matter. (a) Heterotrophs cannot prepare their own food. A saprophyte is a plant that does not have chlorophyll and gets its food from dead matter, similar to bacteria and fungi (note that fungi are often called saprophytes, which is incorrect, because fungi are not plants). If one partner was separated from the other, they would both die. Ask your question.
