Question

1. use the chart below to answer the questions.

observed cell features
cell 1

• nucleoid
• cytoplasm
• plasma membrane

cell 2

• mitochondria
• cytoplasm
• plasma membrane

using a microscope, a scientist observed two cells and recorded several features observed for each cell
part a: the scientist recorded a limited number of observations for each cell. based on the information, classify each cell as either a prokaryote or a eukaryote
cell 1
cell 2
part b: identify another cell structure that would be observed in both cells but is not on the chart and describe the function of this cell structure:
cell structure
function

Explanation:

Part A:

Prokaryotes lack a true - nucleus and have a nucleoid. Eukaryotes have membrane - bound organelles like mitochondria. Cell 1 has a nucleoid and no mitochondria, so it is prokaryotic. Cell 2 has mitochondria, so it is eukaryotic.

Part B:

Ribosomes are present in both prokaryotes and eukaryotes. They are the sites of protein synthesis, translating mRNA into proteins.

Answer:

Part A:

Cell 1: Prokaryote
Cell 2: Eukaryote

Part B:

Cell Structure: Ribosome
Function: Site of protein synthesis
