Biology Quiz: Origin and Characteristics of Life

The idea that life can arise from non-living matter.

Life comes from pre-existing life.

Scientist who challenged spontaneous generation with an experiment using meat and maggots.

The outdated belief that living things can arise from nonliving matter.

Features that distinguish living things from nonliving things. These include gathering and using energy, adapting and evolving, and reproduction.

The ability to do work, which allows living things to grow, move, and reproduce.

The way organisms get food to survive.

Maintaining a stable internal environment.

An experiment that disproved spontaneous generation, showing bacteria only come from pre-existing bacteria.

The basic unit of life.

A single-celled organism without a nucleus, like bacteria.

A more complex cell with a nucleus and organelles.

The ability of a living thing to adjust to changes in its environment.

Changes in the characteristics of a group of organisms over time.

The process of growth and changes in an organism from birth to death.

The jelly-like substance inside a cell, primarily composed of water, where most cellular activity occurs.

The cell's outer boundary that controls the movement of molecules in and out of the cell.

A cell organelle that modifies, sorts, and packages proteins.

Cellular machinery that synthesizes (makes) proteins from amino acids.

The process by which plants convert sunlight into chemical energy.

The organelle in plant cells where photosynthesis takes place.

A storage structure in a cell that can hold food, water, or waste.

The movement of proteins throughout the cell; from the cell, to the Golgi apparatus and other places.

Membranous sacs within chloroplasts where light-dependent reactions of photosynthesis occur. They contain chlorophyll and other pigments that capture light energy.

Organelles involved in various metabolic reactions, including the breakdown of fatty acids and detoxification. They produce hydrogen peroxide as a byproduct.

The slightly enlarged tip of the style where pollen is deposited during pollination.

A long, thin filament in a flower that allows pollen grains to travel from the stigma to the ovary.

The swollen base of a pistil where ovules (eggs) are located and fertilized eggs develop.

The part of a stamen where pollen grains are produced.

A stalk that supports the anther at its tip.

The female reproductive part of a flower, also known as the pistil. It includes the stigma, style, and ovary.

The male reproductive part of a flower. It consists of the anther and filament.

The wall of a ripened ovary, which forms the fruit around the seeds.

The sepals, the outermost layer of the flower, protect the inner parts before the flower blooms.

The ovary of a flower develops into the fruit after fertilization. It protects the seed.

Sepals are green, leaf-like structures that protect the flower bud, while petals are colorful and attract pollinators.

The initial stage of seed germination where water is absorbed by the seed.
