Euglenas are unicellular organisms. They are both self feeder and other feeders. Which statement summarizes the heterotrophic ac
tivities of euglenas? A. They contain chloroplasts with chlorophyll. B. They carry out photosynthesis in sunny places C. They live in water and have tail like structures D. They are colorless and feed on other, smaller cells
The best answer from the list of options is option D (They are colorless and feed on other, smaller cells)
Explanation:
Euglenas have cells that contain chloroplasts, which means they can make their food like plants through photosynthesis, and when it is dark where they can't get sunlight they can also make food by engulfing their prey through the plasma membrane and absorb them. Euglenas are heterotrophic since they call also feed on smaller cells. Their whip-like tail when viewed under the microscope, is colorless. However, the chloroplasts make them appear green and they can also come in red color.
Answer: Leaves in a cactus are modified into spines to reduce loss of water from leaves by transpiration. Then the plant makes from the process of photosynthesis which is performed by the stem.
