Cells and Microorganisms Quiz

Imagine Abigail's cell phone represents an animal cell. What is the function of the phone's case?

• It generates the phone's energy

• It stores apps like games, photos, and messages

• It allows signals and power to enter the phone and sound to leave

• It gives the phone its rigid and rectangular shape

In a science class experiment, Harper is tasked with identifying the organelle known as the "powerhouse" of the cell because it generates energy needed to power cell activities. Which organelle is she studying?

• Nucleus

• Vacuole

• Mitochondria

• Chloroplast

During a science fair, Ethan observed two different types of cells under a microscope. He noted that one type of cell had structures not present in the other. What additional structures do plant cells have that animal cells do not, according to Ethan's observation?

• Cell membrane and mitochondria

• Nucleus and cytoplasm

• Cell wall and chloroplast

• Vacuole and ribosome

During a science project, Arjun explores how to make homemade yogurt. He learns about a microorganism that is not only crucial for turning milk into yogurt but also aids in digestion within the stomach. Which microorganism is it?

• Virus

• Mold

• Algae

• Bacteria

During a school science project, Priya, Isla, and Nora observed a local water body. They noticed a significant amount of algae and researched its effects. What harmful effect can they conclude algae have on the environment?

• It can cause athlete's foot and ringworm

• It can produce colds and flu

• It can create red tide in the ocean which is deadly

• It can spoil crops and food

During a school science project, Grace and Lily observed a plant in the sunlight and discussed which process the plant uses to convert sunlight into energy. What is this process called?

• Photosynthesis

• Respiration

• Digestion

• Fermentation

During a science project, Nora and Maya are examining a leaf under a microscope. They are particularly interested in understanding the function of the green structures they observe. What is the main function of these chloroplasts in plant cells?

• To store water and nutrients

• To provide structural support

• To perform photosynthesis

• To protect the cell from pathogens

Grace is studying plant cells in her biology class. She is curious about the main function of the vacuole in plant cells. What would you tell her?

• To synthesize proteins

• To store DNA

• To provide structural support and store nutrients

• To produce energy

During a biology field trip, Evelyn, Anika, and Michael observed a fallen log covered in mushrooms. What role do these fungi play in the ecosystem?

• They primarily act as predators, hunting smaller organisms.

• They decompose organic matter, recycling nutrients back into the soil.

• They produce oxygen through photosynthesis like plants.

• They increase greenhouse gases by respiring carbon dioxide.

In the context of a biology class project, Ava is explaining the primary function of DNA in cells. What is she most likely to describe?

• To provide energy for cellular processes.

• To act as a catalyst in biochemical reactions.

• To store and transmit genetic information.

• To assist in the synthesis of proteins.
