Euglena Cell Structure and Function | Euglena under Microscope #biologyexams4u #euglena

Euglena is an unicellular protozoan that shows characteristics of both plant and animal cells
0:05
and is an absolute wonder of nature. It has the ability to photosynthesize like a plant
0:11
but it can also move around like an animal. They are not completely autotrophic though
0:17
euglena can also absorb food from their environment just like animals or heterotrophs
0:23
Euglena is found in freshwater ponds and streams all over the world
0:27
and it plays an important role in the food chain. Let us understand the cell structure of Euglena
0:34
Flagellum is a long fine microscopic whip-like structure that Euglena uses to move
0:40
The next structure is the pellicle, a flexible outer membrane made up of protein that supports
0:45
the plasma membrane and allows Euglena to change shape. Nucleus is the controlling center of the
0:51
cell, containing the genetic material. Nucleolus is the structure within the nucleus, that synthesize
0:58
ribosomal RNA for the synthesis of ribosomes, in continuity with the nuclear membrane is
1:04
the endoplasmic reticulum a network of membranes that transports materials throughout the cell Rough ER with ribosomes is involved in protein production Golgi apparatus is an organelle that modifies and packages proteins for transport
1:20
As euglena is autotrophic, chloroplasts are the organelles that contain chlorophyll and are the
1:25
site of photosynthesis. Mitochondria are organelles that produce energy for the cell
1:32
Contractal vacuole removes excess water from the cell. There is a light-sensitive organelle with pigmented granules called eye spot or stigma
1:41
that helps euglena to find light for photosynthesis. Photoreceptor or paraflagellar body is a light-sensitive region detects light and is located near the flagellum
1:52
It assists in phototaxis or movement toward or away from light. Paramelon is the starch-like carbohydrate composed of glucose produced during photosynthesis
2:02
It serves as a food reserve when photosynthesis is not possible. Euglena is also being studied by scientists for its potential uses in biofuels, bioremediation
2:15
nitrocyticals and other applications. Hope you understand the structure of Euglena. Take care, stay blessed, thank you so much
