Question

1. the table above shows four distinct types of cells with the presence or absence of particular organelles denoted by a - (absent) or a + (present). a researcher claims that all living cells must be able to synthesize proteins in order to maintain homeostasis and perform basic functions. what statement supports the scientists claim? a. ribosomes are required for protein synthesis, and all four cell types can synthesize proteins. b. nuclei house the dna, which is the blueprint for proteins. cell types i, ii, and iii can synthesize proteins. c. cell walls are required for cells to maintain their shape to manufacture proteins. cell types ii, iii, and iv can synthesize proteins. d. cells require lysosomes to digest cellular components to convert them into proteins. only cell types i and iii can synthesize proteins.

Explanation:

Ribosomes are the sites of protein - synthesis. Since all four cell types in the table have ribosomes, they can all synthesize proteins, which supports the claim that all living cells must be able to synthesize proteins for homeostasis and basic functions. Nuclei are not the direct site of protein - synthesis, cell walls are not related to protein - synthesis, and lysosomes are for digestion not protein - synthesis.

Answer:

A. Ribosomes are required for protein synthesis, and all four cell types can synthesize proteins.
