Characteristics of Living Things Quiz

Living things need food, air, and water to survive.

Living things increase in size and complexity over time.

Living things can move independently, even if it's just internal movement.

Living things react to changes in their environment. This is called sensitivity.

Living things have a definite life span, from birth to death.

The process by which plants use sunlight, water, and carbon dioxide to make their own food. This food provides energy for the plant to grow.

The process by which living things take in and use food for energy and growth.

The materials needed for growth and life processes. It provides energy for living things.

Things that do not need food, air, or water to survive. They do not grow from within or have life processes.

The ability to move or change position, a key characteristic of living things.

Plants exhibit movement in response to various things, including sunlight, water, and gravity.

Changes in the environment that living things react to, like light, heat, touch, or sound.

The process of releasing energy from food using oxygen, essential for survival in all living things.

A gas released as a byproduct of respiration, often in exchange for oxygen.

Earthworms breathe through their skin, which is thin, moist and has a good blood supply. They absorb oxygen from the air through their skin and release carbon dioxide.

Fish breathe using gills, which extract oxygen from water that is passed over them. They release carbon dioxide into the water.

Plants exchange gases through tiny pores called stomata on their leaves. They take in oxygen and release carbon dioxide during respiration.

Respiration is the process used by all living organisms to get energy from food. This involves using oxygen and releasing carbon dioxide.

Non-living things, like rocks, do not breathe or perform respiration. They don't need energy from food.

A type of plant response where the leaves of a mimosa plant fold up when touched. This response is a protective mechanism.

The process of exchanging gases between the body and the environment. Oxygen is taken in, and carbon dioxide is released.

The process by which living organisms create new individuals of their species.

The process of dandelion flower petals opening during the day and closing at night. A type of plant response to changes in light.

The energy that living organisms obtain from food through respiration is used for various functions.

The removal of waste products from a living organism's body.

Plants produce waste like carbon dioxide (breathing out) and oxygen (from photosynthesis).

Plants can store waste in parts like leaves or bark, then shed them.

Non-living things like rocks don't produce or remove waste products.

The basic unit of life, too small to see with the naked eye.

Organisms made up of only one cell, like bacteria.

Organisms made up of many cells, like humans and plants.

The length of time a living thing exists, from birth to death.

Non-living things do not have a lifespan and exist forever.

A method of plant reproduction where a new plant is created from a piece of a parent plant, like a stem, leaf, or root.

A method of plant reproduction where a new plant grows from a thickened underground stem or root that stores food, with buds that can sprout.

A method of plant reproduction where seeds are planted to produce a new plant.

A thick underground stem or root of a plant that stores food, containing buds for new growth.

A small piece of a plant, usually a stem, root, or leaf, that can be used to cultivate a new plant.

The process by which living things break down food to release energy, often using oxygen and producing carbon dioxide as a waste product.

A seed's ability to release heat due to internal chemical processes, indicating it's alive, even without showing other signs.

The way living things are organized from the simplest level, cells, to complex organ systems. Think of a hierarchy.

Living things are made of cells, while non-living things are composed of other materials like minerals or plastics.

The process of releasing waste products from the body. These wastes are byproducts of the life processes.

The ability of living things to produce offspring. This ensures the continuation of the species.

The ability of an organism to react to changes in its environment. It allows living things to adapt and survive.

The process by which living things increase in size and complexity over time. It is a key characteristic of life.
