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 5th 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 cells have chloroplasts but animal and bacterial cells do not, so plant cells can do photosynthesis and make food from sunlight. Plant cells and bacterial cells have cell walls (plants have cellulose and bacteria have peptidoglycan) while animal cells do not, which shows plants and bacteria get extra protection and support that animals don’t need. Animal and plant cells have a nucleus and mitochondria but bacterial cells do not and are much smaller (bacteria are 1–10 µm while plant cells are 10–100 µm and animal cells 10–30 µm), which shows plant and animal cells are more complex and can make and use energy inside mitochondria while bacteria are simpler.

Reasoning: These structural differences matter because they let each cell type do the jobs needed for its organism: chloroplasts and cell walls help plants make food and stay upright, mitochondria and a nucleus let animal and plant cells do more complicated tasks and get energy. Bacteria being small and simple helps them grow and reproduce quickly and live in lots of different places.
