Which organelle is responsible for producing energy in the form of ATP in eukaryotic cells?

• Nucleus

• Mitochondria

• Ribosome

• Golgi apparatus

What is the main function of ribosomes in a cell?

• Storing genetic information

• Synthesizing proteins

• Producing energy

• Transporting materials

Which molecule carries genetic instructions from DNA to the ribosome for protein synthesis?

• tRNA

• mRNA

• rRNA

• ATP

What is the primary role of DNA in cells?

• Breaking down waste

• Storing genetic information

• Synthesizing lipids

• Transporting proteins

Which process describes the movement of energy through an ecosystem?

• Protein synthesis

• Flow of energy

• DNA replication

• Cell division

Which organelle is directly involved in modifying, sorting, and packaging proteins for secretion?

• Lysosome

• Golgi apparatus

• Chloroplast

• Nucleus

Explain how the structure of the mitochondria supports its function in the cell.

• The smooth outer membrane allows for easy protein synthesis.

• The folded inner membrane increases surface area for ATP production.

• The presence of chlorophyll enables photosynthesis.

• The rigid cell wall provides protection.

Describe the relationship between DNA, RNA, and protein synthesis.

• DNA is converted directly into proteins.

• DNA is transcribed into RNA, which is then translated into proteins.

• RNA stores genetic information for protein synthesis.

• Proteins are synthesized in the nucleus from DNA.

How does the flow of energy in an ecosystem typically begin?

• With decomposers breaking down dead matter

• With consumers eating producers

• With producers capturing energy from sunlight

• With predators hunting prey

Why is the structure of the cell membrane important for its function?

• It allows the cell to produce energy.

• It controls the movement of substances in and out of the cell.

• It stores genetic material.

• It synthesizes proteins.
