Question

Read the following

All living organisms are made of cells, which are the basic units of life.
While cells come in many different forms, scientists classify them into three main categories: plant cells, animal cells, and bacterial cells. Plant cells and animal cells are both eukaryotic cells, meaning they contain a nucleus and other membrane-bound organelles. Bacterial cells, however, are prokaryotic cells, which lack a nucleus and have a simpler internal structure. Despite these differences.

all cells share certain characteristics, such as a cell membrane, cytoplasm, and ribosomes. Understanding the similarities and differences between cell types helps scientists better understand how different organisms
function and survive in their environments.

In a CER FORMAT in a 6th graders response

Answer the following:

Claim (1 sentence): Write a statement that answers this question: How do the structures of plant cells, animal cells, and bacterial cells reflect their different functions in
organisms?
Evidence (3 sentences): Use at least three pieces of information from the passage and data table to support your claim. Explain what each piece of evidence shows about cell structure and function.
Reasoning(2 sentences ) Explain why the structural differences between
these cell types matter. How do these differences help each type of cell perform its role in an organism?

Answer 1

Claim: Plant, animal, and bacterial cells have different structures that help them do different jobs in living things.

Evidence: Plant and animal cells both have a nucleus and mitochondria (table), which shows they are eukaryotic and can store DNA and make lots of energy for complex tasks. Plant cells have a cell wall made of cellulose and chloroplasts (table), which helps them stay upright and make food from sunlight, while animal cells do not. Bacterial cells are much smaller (1–10 µm), have a peptidoglycan cell wall, and no nucleus (table), and like all cells they still have a cell membrane, cytoplasm, and ribosomes (passage), which shows bacteria are simpler but well protected and able to grow quickly.

Reasoning: These structural differences matter because they let each cell do what its organism needs—plants need rigid cells and chloroplasts for photosynthesis, animals need flexible cells and mitochondria for movement and energy, and bacteria are small and simple so they can reproduce fast and survive in many places. Because of these special structures, each cell type is better suited to its role in the organism and environment.
