I think Fall but you should double check just in case. :)
Euglena move from one place to another like an animal. When they manufacture their own food, they have to move to such an area where they can receive required amount of sunlight. There are two features on its body that facilitate in its movement. The most important is the flagellum, which is a long whip-like appendage attached to the body. It turns and twists in the water in order to push the body through the water. The other physical feature that plays a vital role in giving a sense of direction to its movement is the eyespot, also located at the anterior of its body. It is a light-sensitive, pigmented organelle which is capable of detecting sunlight. Thus, it orients the movement towards the direction of light, where they can collect sunlight required for making food.The ability to move plays a significant role in vital life processes of Euglena, such as the synthesis of food. Hope that helps ;)

Answer:
The phospholipid will form a sphere with the heads inside
Explanation:
Phospholipids are glycerol molecules containing two Fatty acids that is hydrophobia and a hydrophillic negatively charged phosphate.
The phosphate forms the head and the two fatty acids will form the tail
When phospholipid is dropped into a cup of vegetable oil (a lipid). The phospholipid will form a sphere with the heads inside. This is because the heads are hydrophillic and cannot dissolve in the fat hence they will cluster together.
