Discover how Euglena reacts when exposed to sunlight and half of its jar environment is covered with black paper. Will it move to the top or bottom half?
E N D
Use the diagram below to answer this question. Euglena are single-celled organisms. The flagellum helps the organism move through water. Euglena are similar to plants in the way they obtain their food. Nina kept several euglena in a glass jar. She wondered what would happen if she covered the top half of the jar with black paper and placed it in sunlight. Which is the best prediction of how the euglena will respond to the change in the jar environment? A. Most of the euglena will move to the bottom half of the jar. B. Most of the euglena will move to the top half of the jar. C. The euglena will spread out evenly throughout the jar. D. The euglena will move back and forth between both halves.
