1. diploid- To be diploid means for an organism to have two sets of chromosomes in each cell, one from each parent. All organisms and cells are diploid except gametes. The cells that make up this heron are diploid cells.
2. ethylene- As vegetables and fruits ripen, they let off a gas called ethylene. Eventually, the produce begins to rot do to the "overdose" of the gas (such as this bell pepper plant).
3. eukaryote- Cells with a distinct nucleus and membrane bound organelles are called eukaryotic cells. Eukaryotes are the organisms that are composed of eukaryotic cells. Examples of eukaryotes include: animals, plants (such as the Boxwood plant above), protoctists , and fungi.
7. evidence of different alleles- Alleles are genetic codes that decide the genotype and phenotype of an organism. Each of the organisms' parents both supply one allele for each genetic trait. Certain alleles may be dominant or recessive over the other to block it from affecting the phenotype of the organism. The chickens each express different alleles for feather color. One chicken is white, the other is brown, and the other is black.
8. flock, herd, or schooling- The turkeys, on the other side of the fence, are in a flock. A flock is simply a group of animals of the same species.
10. genetically modified organism (GMO)- A GMO is an organism that has been purposefully genetically altered to show physical, desired traits. Rice (and other grains) and many vegetables have been modified so that the plants can more easily defend against diseases.
14. mitosis- Mitosis is one of the processes eukaryotic cells go through to divide for growth and reproduction. The five steps of mitosis are commonly called: interphase, prophase, metaphase, anaphase, and telophase. Plant cells (such as the cells from this Christmas Cactus) are eukaryotic and therefore go through mitosis.
16. phenotype- The physical visible alleles expressed in an organism that is determined by the genotype. The phenotypes of these mice include white fur and long tails.
17. pollinator- A pollinator is an organism that transfers pollen from the male parts of a flower to the female parts of the flowers. Examples of pollinators include bees (such as the one above) and some birds.
20. tropism- Tropism is the bending movement an organism makes as it grows due to outside forces such as light, heat, and gravity. The vines of this vine plant are growing down because of the affect gravity.
