This structure is known as the powerhouse of the cell

what is mitochondria

100

This is the process plant cells use to turn sunlight, water, and carbon dioxide into food.

what is photosynthesis

100

This molecule looks like a twisted ladder and holds all genetic code for a living organism

what is DNA

100

This system includes the heart and blood vessels, moving oxygen and nutrients throughout the body.

what is the circulatory system

100

Organisms that must eat other living things to get energy are given this scientific name

what are consumers

200

This jelly-like fluid fills the inside of a cell and holds all the organelles in place.

What is cytoplasm

200

This cellular process breaks down glucose to release energy when oxygen is present

what is cellular respiration

200

This type of allele always masks or hides a recessive allele when they are paired together

what is a dominant allele

200

This system removes liquid and gaseous waste from the body to keep internal conditions balanced

what is the excretory system

200

A structure that used to serve a purpose but no longer does

what is vestigial

300

This thin, flexible barrier surrounds all cells and controls what goes in and out.

what is the cell membrane

300

This type of cell division creates two identical daughter cells for growth and tissue repair

what is mitosis
300

This four-box grid tool predicts the mathematical probability of an offspring inheriting specific traits.

what is a Punnett square

300

This is the scientific term for the body's ability to maintain a stable, balanced internal environment

what is homeostasis

300

This process explains how organisms with traits best suited to their environment are more likely to survive and reproduce

what is natural selection

400

These tiny structures are responsible for making proteins inside the cell

what are ribosomes

400

This is the passive movement of water molecules across a selectively permeable membrane.

what is osmosis

400

This is the scientific word for the physical appearance of an organism, like having blue eyes

what is a phenotype

400

These tiny, finger-like projections in the small intestine absorb nutrients into the bloodstream.

what are villi

400

This ecological term describes the maximum population size that an environment can sustainably support

what is carrying capacity

500

This organelle breaks down waste, old cell parts, and foreign invaders like a cell's trash disposal.

what is lysosome

500

In cell division, what is the splitting of cytoplasm called?

what is cytokinesis

500

An organism that inherits two different alleles for a trait (like one dominant and one recessive) is called this

what is heterozygous

500

This system uses chemical messengers called hormones to regulate growth, mood, and metabolism

what is the endocrine system

500

These are the physical or behavioral traits that help an organism survive in its specific habitat.

what are adaptations
