Plant Cell Basics

What is the function of the cell wall in a plant cell?

• Energy production

• Structural support and protection

• Waste removal

• Cell division facilitation

Name the organelle responsible for photosynthesis in plant cells.

• Mitochondria

• Chloroplast

• Endoplasmic Reticulum

• Nucleus

Which part of the plant cell is responsible for storing water, nutrients, and waste?

• Vacuole

• Mitochondria

• Chloroplast

• Ribosome

What is the function of the vacuole in a plant cell?

• Helps in photosynthesis

• Regulates cell division

• Stores water, nutrients, and waste products; maintains turgor pressure; provides structural support.

• Synthesizes proteins

What is the function of chloroplasts in plant cells?

• Photosynthesis

• Nutrient absorption

• Cell division

• Oxygen production

Explain the difference between a light microscope and an electron microscope.

• A light microscope uses sound waves, while an electron microscope uses radio waves.

• A light microscope uses X-rays, while an electron microscope uses gamma rays.

• A light microscope uses infrared light, while an electron microscope uses ultraviolet light.

• A light microscope uses visible light, while an electron microscope uses a beam of electrons.

What is the magnification range of a light microscope?

• 30x to 1200x

• 50x to 800x

• 40x to 1000x

• 20x to 500x

How does an electron microscope differ from a light microscope in terms of magnification?

• Electron microscopes have higher magnification capabilities than light microscopes.

• Electron microscopes have lower magnification capabilities than light microscopes.

• Electron microscopes have the same magnification capabilities as light microscopes.

• Light microscopes have higher magnification capabilities than electron microscopes.

What is the purpose of staining samples in microscopy?

• To increase the weight of the sample

• To enhance contrast and visibility of specific structures within the sample.

• To make the sample smell better

• To add flavor to the sample

Explain the importance of using a cover slip when observing samples under a microscope.

• Not using a cover slip allows for better airflow and sample observation.

• Using a cover slip helps to flatten the sample, prevent evaporation, protect the objective lens, and improve image resolution.

• Cover slips increase the risk of sample contamination.

• Using a cover slip distorts the sample, causing inaccurate observations.
