- - As Euglenas are capable of photosynthesis, demonstrated by positive phototaxis, the ability of controlled movement toward a light source, detected by the eyespot.
- - As Euglenas are capable of photosynthesis, they produce glucose from carbon dioxide by using photo-energy. Glucose is then synthesized into polysaccharides which are stored in granules and used as nutrient reserves.
- - Food enters through it, then it is absorbed by endocytosis.
- - It is the "reactor" of cells: produces ATP by breaking down organic material.
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.
