Leylah was observing a specimen using a microscope. She observed a group of cells on the slide. She noticed they were different shapes. Some were clumped together and some formed chain-like shapes, with no visible nucleus in the middle of the cells. They also did not contain any structures that would allow them to move independently. She concluded she was looking at eukaryotic cells from a multicellular organism. Her lab partner Heidi disagreed and insisted that they were observing a group of prokaryotic bacteria cells. Who is correct, and which piece of evidence supports the correct claim?(1 point)

Answer 1

Leylah is correct. The evidence that supports Leylah's claim is that the cells were uniform with no structures for movement. This suggests that they are eukaryotic cells from a multicellular organism. Prokaryotic bacteria cells typically have different shapes and can form clumps, and they typically have structures like flagella that allow them to move independently. None of these characteristics were observed in the specimen.
