Compare the organisms in the table. what plantlike characteristic does a methanogen share with organisms in the kingdom plantae?
ikadub [295]
Plantlike and methanogen organisms share som similar characteristics, for instance, can both produce their own and can process their made food into energy for different cellular processes such as cell division, repair and maintenance.

Despite this similarity though, the difference lies with the source of energy that get to produce the food. Plantlike organisms use sunlight and UV rays to photosynthesize. Whereas, methanogens use methane where sunlight is not present.

Protists are very diverse, and many different classification schemes have been used to define relationships between the protists
andrey2020 [161]

Answer:

D. heterotrophic by ingestion, pseudopods

Explanation:

Protists are generally classified  as all eukaryotic organisms that are not plants, animals or fungi. Example is amoeba, paramecium etc.They may be unicellular or multi cellular in nature.Most exist in colonies.

Their mode of nutrition can be photosynthetic or hetrotrophic. Hetrotrophic  protists   can be divided into  phagotrophs and osmotrops/saprotrophs. The phagotrophs  makes use of the cell body to engulf the food materials as  in amoeba ,carry out extracellular digestion before swallowing it.

Osmotrops absorbed dissolved food from surrounding liquid environments directly. (Some photosynthetic protists can also be heterotrophic.

Amoeboid movement is the mode of locomotion of protists and some  other eukaryotes. It involved the protrusion of cytoplasm, which exert pressure on the cell membrane to form pseudopodia and  the posterioly  evolved  <u>Uropods. </u>

<u />

<u>  </u>

<u>Sol-gel theory has been proposed to expalin this movements, The ectopalsm of amoeba is gelly-like , while the endiplams is less viscpus   and said to be sol. The interchange of the cytoplasmic fluis between the endo-and ecto plasm gives the SOL-GEL propulsion of the protopalms for the amoebic moveemnts .</u>

<u />

<u>The false feet(psuedopodium) drags the amoeba  along in the direction of the flow of the cytoplasm.</u>

Therefore option D is  the right option
