#1
Which organelle is responsible for producing energy in the cell?
Mitochondria
ExplanationMitochondria produce energy in the form of ATP through cellular respiration.
#2
What is the function of chloroplasts in plant cells?
Photosynthesis
ExplanationChloroplasts conduct photosynthesis, converting light energy into chemical energy.
#3
What is the role of ribosomes in the cell?
Protein synthesis
ExplanationRibosomes are responsible for protein synthesis in the cell.
#4
Which structure is responsible for maintaining cell shape and providing mechanical support?
Cytoskeleton
ExplanationThe cytoskeleton maintains cell shape and provides structural support.
#5
Which type of biological interaction benefits both participating organisms?
Mutualism
ExplanationMutualism involves a mutually beneficial relationship between two organisms.
#6
What is the primary function of the rough endoplasmic reticulum?
Protein synthesis
ExplanationThe rough ER is involved in protein synthesis and processing.
#7
What is the function of the Golgi apparatus in the cell?
Processing and packaging proteins
ExplanationThe Golgi apparatus processes and packages proteins for transport.
#8
Which type of biological interaction involves one organism benefiting while the other is harmed?
Predation
ExplanationPredation involves one organism consuming another for its own benefit.
#9
Which of the following is not a function of the cell membrane?
Energy production
ExplanationThe cell membrane primarily regulates the passage of substances and is not involved in energy production.
#10
What is the main function of the nucleus in eukaryotic cells?
DNA storage and replication
ExplanationThe nucleus stores and replicates DNA, the genetic material of the cell.
#11
Which of the following is not a component of the cytoskeleton?
Ribosomes
ExplanationRibosomes are not part of the cytoskeleton; they are involved in protein synthesis.
#12
Which structure is responsible for regulating the passage of substances into and out of the cell?
Plasma membrane
ExplanationThe plasma membrane regulates the movement of substances into and out of the cell.
