Given a scientific passage and an answer, generate a question for the given answer.

[Q]: Passage: Sponges come in a variety of shapes and sizes. For example, they may be shaped like tubes, fans, cones, or just blobs. They range in diameter from about a centimeter (0.4 inches) to over a meter (3.3 feet). Many species live in colonies that may be quite large. Adult sponges are sessile. This means they are unable to move from place to place. Root-like projections anchor them to solid surfaces such as rocks and reefs. Answer: sponges
[A]: Root-like projections anchor adults of what colony-dwelling animals to solid surfaces such as rocks and reefs?

[Q]: Passage: 30.1 | The Plant Body By the end of this section, you will be able to: Describe the shoot organ system and the root organ system Distinguish between meristematic tissue and permanent tissue Identify and describe the three regions where plant growth occurs Summarize the roles of dermal tissue, vascular tissue, and ground tissue Compare simple plant tissue with complex plant tissue Like animals, plants contain cells with organelles in which specific metabolic activities take place. Unlike animals, however, plants use energy from sunlight to form sugars during photosynthesis. In addition, plant cells have cell walls, plastids, and a large central vacuole: structures that are not found in animal cells. Each of these cellular structures plays a specific role in plant structure and function. Answer: animal cells
[A]: Cell walls, plastids, and a large central vacuole distinguish plant cells from what?

[Q]: Passage: Nucleotides are composed of a phosphate group, a sugar, and one of five different nitrogenous bases. Answer: nucleotides
[A]:
What are composed of a phosphate group, a sugar, and one of five different nitrogenous bases.
