Answer:
1. EUGLENA
1. Are euglena unicellular or multicellular?
= Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta.
2. What Kingdom do euglena belong to? What Phylum?
= Euglena belongs to Kingdom Protista and the Phylum Euglenophyta.
3. What organelle carries out photosynthesis?
= Chloroplasts carries out photosynthesis.
4. On which end is the flagellum located?
= The flagellum is located on the anterior (front) end, and rotates in such a way as to pull the cell through the water.
5. Define autotrophic.
= Autotrophs are known as producers because they are able to make their own food from raw materials and energy.
6. Define heterotrophic.
= Heterotrophs are known as consumers because they consume producers or other consumers.
7. Describe the two ways in which the euglena get their nutrients.
- Euglena can gain nutrients by sunlight absorbing them across their cell membrane.
- All Euglena have chloroplasts and can make their own food by photosynthesis in which they get nutrients.
8. What is the eyespot used for?
= Euglena have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food.
9. What is the function of the nucleus?
= The function of the nucleus is it contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus.
10. What is the function of the contractile vacuole? What would happen if the cell did not have this organelle.
= The function of the contractile vacuole is that, it helps the cell remove excess water. If the cell did not have this organelle, the euglena could take in some much water due to osmosis that the cell would explode.

2. Amoeba
1. How does an amoeba move?
= the amoeba has an unusual way of creeping along by stretching its cytoplasm into fingerlike extensions called pseudopodia. "pseudopodia" means "false foot".
2. What structure contains the ameba's DNA?
= Nucleus contains the amoeba's DNA.
3. How does an ameba reproduce?
= In order to reproduce the ameba goes through mitotic division, where the nucleus duplicates its genetic material and the cytoplasm splits into two new daughter cells, each identical to the original parent. This method of reproduction is called binary fission.
4. During unfavorable conditions, an ameba forms a ... ?
= During unfavorable conditions, the ameba can create a cyst, this hard walled body can exist for a long period of time until conditions become favorable again.
5. Fingerlike extensions of the ameba's cytoplasm are called ...?
= The Fingerlike extensions of the ameba's cytoplasm are called .l Pseudopodia.
6. What disease is caused by the ameba?
= A common disease caused by the ameba is called Amebic Dysentery.
7. To what Kingdom does the ameba belong?
= The amoeba belongs to the Kingdom Protista.
8. How are protists classified?
= Protists are classified into plant-like while others are considered animal-like.

=
