Plants are multicellular eukaryotes; their cells contain membrane-bound structures called organelles. ... During photosynthesis, plants make their own food by converting light energy into chemical energy, a process carried out in the green cellular organelles called chloroplasts Parts of the Plants Cells: The many varieties of plant species have distinct cell types that make up individual plants. ... Each individual plant cell is at least partly self-sufficient, being isolated from its neighbors by a cell membrane, or plasma membrane, and a cell wall. The membrane and wall allow the indiv...

The aerobic prokaryote was enclosed by the bacterium's cell surface membrane in the process of endocytosis, which is made easy by the absence of a cell wall in the bacterium. The aerobic prokaryote wasn't digested but continued to function inside the other cell. The host cell received energy that the aerobic prokaryote released. ... Darwin observed that wild animals and plants showed variations just as domesticated animals and plants did. ...

Subclass Pelobiontae includes one genus, Pelomyxa, large cells which lack almost every characteristic of eukaryotic cells except the existence of a membrane-bound nucleus; these cells' nuclei divide like bacterial nucleoids. ... Microsporans are also parasitic; they use their polar filament to inject sporoplasm (an infective body) into host cells. ... Many dinomastigotes have cells below the cell membrane that are capable of discharging a substance tha...
