Guida verificata passo dopo passo1
Step 1: Begin by identifying the key features of prokaryotic cells. Prokaryotic cells are simple, single-celled organisms that lack membrane-bound organelles, including a nucleus. Their genetic material is stored in a nucleoid region, and they often have a cell wall made of peptidoglycan.
Step 2: Next, examine the characteristics of modern-day green plant cells. These are eukaryotic cells, meaning they have membrane-bound organelles, including a nucleus where genetic material is stored. They also have a cell wall, but it is composed of cellulose, and they contain chloroplasts for photosynthesis.
Step 3: Compare the options provided in the question to the features of both cell types. Option 1 states that both store genetic material within a membrane-bound nucleus, which is incorrect because prokaryotic cells lack a nucleus. Option 3 states that both lack ribosomes for protein synthesis, which is incorrect because both cell types have ribosomes for protein synthesis.
Step 4: Evaluate Option 4, which states that both contain chloroplasts for photosynthesis. This is incorrect because prokaryotic cells do not have chloroplasts; photosynthetic prokaryotes like cyanobacteria use other structures for photosynthesis.
Step 5: Confirm that Option 2 is correct. Both prokaryotic cells and green plant cells have a cell wall, although the composition differs: prokaryotic cell walls are made of peptidoglycan, while plant cell walls are made of cellulose.
