Explanation / Answer
Meiosis - A haploid cell that combines with another haploid cell during fertilization
Gene - A specific portion of a chromosome that contains information for a particular inherited trait
Crossing over - An interaction during meiosis in which chromatids exchange segments; it results in genetic recombination
Mitochondria - Extracts energy stored in carbohydrates; synthesizes ATP; produces water and carbondioxide
ATP - Nucleotide that drives most energy-requiring metabolic reaction
Translation - The process in which ribosomes synthesize proteins using the mRNA transcript
Transcription - The synthesis of mRNA from a DNA template
Microtubules - Are primary cellular structures (or components) where proteins are assembled
Chloroplast - Converts light energy to chemical energy stored in the chemical bonds of glucose or starch
Chromosome - DNA with attached protein
