Which organelle is responsible for producing energy (ATP) in a eukaryotic cell?
Answer: Mitochondria
Mitochondria are the 'powerhouses of the cell,' producing ATP through cellular respiration using oxygen and glucose.
Which process do plants use to convert light energy into chemical energy (food)?
Answer: Photosynthesis
Photosynthesis is the process plants use to capture light energy and convert it into glucose (chemical energy), releasing oxygen as a byproduct.
What is the correct order of levels of biological organization from smallest to largest?
Answer: Cell → Tissue → Organ → Organ system → Organism
Biological organization from smallest to largest: Cell → Tissue → Organ → Organ system → Organism.
In a food chain, which organism is the PRIMARY producer?
Answer: Grass
Producers (like grass) make their own food through photosynthesis. They form the base of food chains and are called autotrophs.
Which of the following best describes the function of DNA in cells?
Answer: Contains genetic instructions for building proteins
DNA (deoxyribonucleic acid) stores genetic information in the form of base sequences that code for proteins, which carry out most cellular functions.
Which type of reproduction produces offspring that are genetically identical to the parent?
Answer: Asexual reproduction
Asexual reproduction involves one parent and produces genetically identical offspring (clones) through processes like budding, fission, or vegetative propagation.
