What is the primary role of the nucleus in a cell?

Which of the following is NOT a function of the cell wall in a plant cell?

Which of these describes the process of photosynthesis?

Which of the following is a key difference between plant cells and animal cells?

Which of the following is NOT a characteristic of a compound microscope?

Characteristics of Living Things

Living things grow, reproduce, and repair themselves
Living things need energy
Living things respond to changes in their environment
Living things have a lifespan
Living things produce waste

Plants and Animals

Plants and animals grow larger as they age
Living things reproduce to create offspring
Living things repair damaged parts
Plants use sunlight as an energy source
Animals eat plants, other animals, or both to obtain energy
Animals attempt to avoid predators
Plants grow roots to find moist soil
Living things have life cycles—they grow and die

Compound Microscope

Used to view cells
Uses lenses and light to magnify specimens
Magnification increases the apparent size of a specimen
Field of view is the area of the specimen seen through the eyepiece

Plant and Animal Cells

Nucleus: The control center of the cell, containing genetic information (DNA) that directs all cell functions.
Plant Cells Only: Cell wall (rigid structure that supports and protects the cell) and chloroplasts (sites of photosynthesis, where plants use sunlight to make food)

Cell Movement in Animal Cells

Flagella and Cilia: Structures that help animal cells move.
Flagella: Long, whip-like structures that propel the cell through the environment
Cilia: Hair-like projections that help move the cell or substances around the cell.

Explore the fundamental traits of living organisms, including their growth, energy needs, and life cycles. Understand the role of plant and animal cells, and how a compound microscope helps in studying them. This quiz delves into the characteristics that define life and the structures of cells.
