How was Euglena formed?
Reproduction. Euglena reproduce asexually through binary fission, a form of cell division. Reproduction begins with the mitosis of the cell nucleus, followed by the division of the cell itself.
How does Euglena grow and develop?
Euglena are single cellular which means they produce asexually. Euglenas are found in salt and fresh waters. They can feed like animals or through the process of photosynthesis. They grow and develop slowly and mostly by phototrophy.
Is an Euglena alive?
The Euglena. Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta. They are not completely autotrophic though, euglena can also absorb food from their environment; euglena usually live in quiet ponds or puddles.
What is the order of Euglena?
Euglenales
Euglena/Order
What does the reservoir do in a euglena?
Reservoir: part of a euglena used for storage.
Where does the name euglena come from?
The name Euglena comes from the Greek “eu” which means “good,” and “glene” which means “eyeball” and refers to the distinct eyespot which can be seen in most euglenoid cells (Fig. 3.4).
How does a euglena create energy?
Euglenas create their own food through photosynthesis, the process of absorbing sunlight to synthesize foods from carbon dioxide and water. An eyespot at the front end of the euglena detects light, and its chloroplasts (structures that contain chlorophyll) trap the sunlight, allowing photosynthesis to occur.
What are two ways Euglena get their nutrients?
Euglena quesitons
| Question | Answer |
|---|---|
| define autotroph | can make its own food |
| define heterotroph | must consume food |
| describe the two ways in which the euglena get their nutrients. | trap sunlight; absorb food across their cell membrane |
| what is the eyespot used for? | to find bright areas to gather sunlight |
How does Euglena move about in water?
Euglena move by a flagellum (plural flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water. It is attached at an inward pocket called the reservoir.
