An organelle found in plant and algae cells where photosynthesis occurs

Diffusion of water

A summary based on evidence or facts, made at the END of the experiment

organisms (like bacteria and fungi) that break down wastes and dead organisms

Control center of the cell; contains DNA

process by which organisms maintain a relatively stable internal environment

A cell structure that controls which substances can enter or leave the cell.

Variable that is changed in the experiment

any disease-producing agent (especially a virus or bacterium or other microorganism)

Whip-like structures that help with cell movement

a chemical substance derivable from a mold or bacterium that kills microorganisms and cures infections

The process of grouping things based on their similarities

Organic molecule your body uses for quick energy; Broken down to simple sugars

Cell organelle that stores materials such as water, salts, proteins, and carbohydrates

Animal that feeds on plants

Makes ribosomes

organism made of one cell

In an experiment, the standard that is used for comparison, that does NOT get the experimental treatment

A cell that contains a nucleus and membrane bound organelles. Ex. Plants and animals

An attraction between molecules of different substances

An accepted explanation of something based on many observations and experiments.

An animal with a backbone

Organisms able to make their own food (Same as a producer)

Organisms that must eat food to obtain energy (Same as a consumer)

Equal concentration; stays the same

any animal lacking a backbone

Less liquid inside of the cell; Shrinks

organism made of many cells

A single‐celled organism that does not have a nucleus or specialized organelles. Ex. Bacteria

More liquid inside of the cell; Swells

heterotrophs that digest food outside of their body and absorb nutrients; a kind of decomposer

Building blocks of protein

A segment of DNA on a chromosome that codes for a specific trait

a chart showing the descendants of one individual

Describes a trait that covers over, or dominates, another form of that trait.

More liquid inside of the cell; Swells

Traits that are determined by genes carried on the sex chromosomes (on the X chromosome in particular)

Variable that is measured during an experiment

the second stage of mitosis/meiosis

the process of generating offspring

an insect that carries pollen from one flower to another

The different forms of a gene

DNA coiled around and supported by proteins, found in the nucleus of the cell.

A random change in the DNA of a gene, ultimately creating genetic diversity; a change in the DNA that can result in a different protein

a sugar (like sucrose or fructose); the simplest group of carbohydrates

the first stage of mitosis/meiosis

Organic macromolecule that stores energy and is used for insulation; includes fats, oils, and waxes

Made of amino acids; essential in the diet of animals for growth and for repair of tissues; can be obtained from meat and eggs;

An allele that is always expressed;

The joining of a sperm and an egg

Sex cells

before mitosis; the period of the cell cycle during which the nucleus is not undergoing division;

an organism or cell having two sets of chromosomes or twice the haploid number

Chromosomes become visible, nuclear envelope dissolves, and spindle forms

Having two identical alleles for a trait

Having two different alleles for a trait

A process of asexual reproduction in eukaryotic cells; two cells are made with the same number of chromosomes

DNA replicates and organelles are copied

A type of protein that speeds up a chemical reaction in a living thing

Process by which a single parent reproduces by itself

an organism or cell having only one complete set of chromosomes (half the number)

An allele that is masked when a dominant allele is present; Allele that is not expressed unless two copies are present in an organisms genotype
