Widespread heterotrophic unicellular organisms with constantly changing shapes
Common ciliated eucaryotic unicellular organisms widespread in freshwaters.
Chlorophyll is a photosensitive green pigment found in plants; it absorbs light energy, thus plays a vital role in photosynthesis.
Jellyfish are free-swimming marine animals, a species of Cnidaria, the most ancient group of Eumetazoans.
Plants are capable of converting inorganic substances (carbon dioxide and water) into organic sugar.
There are two basic cell types: prokaryotic and eukaryotic cells.
Viruses consist of protein and DNA or RNA; they reprogram infected cells to produce more viruses.
Eukaryotic cells contain a number of organelles.
Bacteria occur in a wide range of shapes, including spheres, rods and spirals.
