The Euglena identifies a light source and move toward it so photosynthesis can occur "by using eyespots and flagella"
When euglena undergoes photosynthesis, it detect light through its eyespot and move toward it. This process is known as phototaxis. It uses its flagella to move toward the light. The flagella is a long whip-like structure which is used by the euglena to move.
The Euglena is both a heterotrophic and an autotrophic organism. The euglena has chloroplasts which trap sunlight that is used for photosynthesis.
Lister's work led to a reduction in post-operative infections and made surgery safer for patients, distinguishing him as the "father of modern surgery"
Animals have so many different enzymes to digest their food they eat variety of food in their diet so specif enzymes are needed to digest each type of food
metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under this condition because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.
