Question

bio.1.1.1 summarize the structure and function of organelles in eukaryotic cells: match these organelles with their functions (middle school review) nucleus a. sites of photosynthesis contain chlorophyll. plasma membrane b. powerhouse of the cell, where cell respiration occurs. cell wall c. brain of the cell, contains the dna & chromosomes. mitochondria d. sites of protein synthesis, where mrna & trna meet. vacuoles e. cells outer boundary, lipids & proteins, semipermeable. chloroplast f. found in plants only to maintain structure, not semipermeable. ribosomes g. large in plants, small in animals, used for storage.

Explanation:

• Nucleus: It is the control center (brain) of the cell that stores genetic material (DNA and chromosomes), so it matches with option C.
• Plasma membrane: Composed of lipids and proteins, it acts as the cell's outer boundary and is semi - permeable (regulates what enters and exits the cell), so it matches with option E.
• Cell wall: Found only in plant cells (in the context of common eukaryotic cells taught at a basic level) and provides structural support (not semi - permeable like the plasma membrane), so it matches with option F.
• Mitochondria: Known as the powerhouse of the cell because it is the site of cellular respiration (produces ATP, the energy currency of the cell), so it matches with option B.
• Vacuoles: In plant cells, they are large and used for storage (of water, nutrients, etc.), while in animal cells, they are smaller, so it matches with option G.
• Chloroplast: Contains chlorophyll and is the site of photosynthesis (converts light energy into chemical energy), so it matches with option A.
• Ribosomes: The site of protein synthesis where mRNA (messenger RNA) and tRNA (transfer RNA) interact to build proteins, so it matches with option D.

Answer:

Nucleus - C. Brain of the cell, contains the DNA & chromosomes.
Plasma membrane - E. Cell's outer boundary, lipids & proteins, semipermeable.
Cell wall - F. Found in plants only to maintain structure, not semipermeable.
Mitochondria - B. Powerhouse of the cell, where cell respiration occurs.
Vacuoles - G. Large in plants, small in animals, used for storage.
Chloroplast - A. Sites of photosynthesis contain chlorophyll.
Ribosomes - D. Sites of protein synthesis, where mRNA & tRNA meet.
