100

This organelle acts as the powerhouse of the cell, generating ATP energy through cellular respiration.

What is the Mitochondria?

100

This double-helix shaped molecule carries the genetic instructions for all living things.

What is DNA?

100

This green pigment inside chloroplasts absorbs sunlight to power photosynthesis.

What is Chlorophyll?

100

This term describes an organism that can make its own food using energy from the sun.

What is a Producer (or Autotroph)?


100

This scientist is famous for developing the theory of evolution by natural selection after studying finches in the Galápagos Islands.

Who is Charles Darwin?

200

Unlike animal cells, plant cells have this rigid outer layer that provides structural support and protection.

What is the Cell Wall?

200

This is the specific type of cell division that produces four genetically diverse daughter cells (gametes) with half the original DNA.

What is Meiosis?

200

These are the two primary products created by the process of photosynthesis.

What are Glucose and Oxygen?

200

This is a non-living physical or chemical factor in an ecosystem, such as sunlight, water, or temperature.

What is an Abiotic factor?

200

These are remnants or traces of ancient organisms preserved in rock that provide evidence for evolution.

What are Fossils?

300

This is the jelly-like fluid that fills the cell and holds all the organelles in place.

What is the Cytoplasm?

300

An allele that can mask or hide the expression of another allele is known as this.

What is a Dominant Allele?

300

This type of cellular respiration does not require oxygen to break down sugars.

What is Anaerobic Respiration (or Fermentation)?

300

This type of symbiotic relationship happens when both organisms benefit from interacting with each other.

What is Mutualism?

300

This term describes body parts in different species that share a similar structure because they evolved from a common ancestor, like a human arm and a whale flipper.

What are Homologous Structures?


400

This organelle contains digestive enzymes to break down waste, worn-out cell parts, or foreign invaders.

What is a Lysosome?

400

This term describes an organism that has two different alleles for a specific trait (like Bb).

What is Heterozygous?

400

These are the tiny pores on the underside of leaves that allow gas exchange (carbon dioxide in, oxygen out).

What are Stomata?

400

This law states that only about this percentage of energy is transferred from one trophic level to the next highest level in an energy pyramid.

What is the 10% Law?

400

This is the highest and broadest level of classification for organisms, sitting above the kingdom level.

What is a Domain?

500

This type of transport requires cell energy (ATP) to move molecules against their concentration gradient from low to high concentration.

What is Active Transport?

500

This is a mistake or permanent change in the nucleotide sequence of DNA.

What is a Mutation?

500

Cellular respiration takes place primarily in this organelle.

What is the Mitochondria?

500

This term refers to the maximum population size of a species that a specific environment can sustainably support.

What is Carrying Capacity?

500

This two-word naming system uses an organism's Genus and species names to give it a scientific name.

What is Binomial Nomenclature?
