Mitosis

A process of cell division that results in two identical daughter cells.

Pigment chromatography

A technique used to separate and analyze pigments based on their light absorption properties.

Cell cycle checkpoints

Control mechanisms in the cell cycle that ensure the accuracy of DNA replication and division.

Cypress sprigs in light vs. dark

An experiment to measure oxygen production and photosynthesis under different light conditions.

Chi-square test

A statistical method used to determine whether observed genetic outcomes match expected ratios.

Phenol red

An acid-base indicator that shows pH changes related to CO2 exchange in experiments.

Onion root tip

Tissue type commonly used to observe stages of mitosis due to active cell division.

Expected outcome of Pp x Pp cross

A 3:1 ratio of dominant to recessive traits in the offspring.

Starch presence in Coleus leaf
