Science

3. A physical characteristics of an organism.
6. A kingdom of organisms that can perform photosynthesis to make food. Characteristics include multi-cellular, eukaryotic, autotrophic, and mostly green in color.
7. The green substance inside chloroplasts that absorbs energy from sunlight to use in photosynthesis.
9. deoxyribonucleic acid, the material found in the nucleus of a cell that contains the information that determines inherited characteristics.
15. The process of producing ATP in the cell from oxygen and glucose; releases carbon dioxide and water.
16. a form of cell division that produces reproductive haploid cells in sexually reproducing organisms.
17. a form of cell division in which the nucleus divides into nuclei containing the same number of chromosomes.
19. threadlike structures made of DNA molecules that contain the genes.
20. The different forms of a gene.

1. A mature sexual reproductive cell having a single set of unpaired chromosomes. Has half the number of chromosomes (Ex: egg and sperm).
2. A science of manipulating the genes of living things to instill some desirable trait not present in the original organism (Ex: a tomato given a gene to delay its rotting).
4. The process by which plants capture light energy from the sun and convert it into sugars.
5. A sequence of DNA that codes for a protein and thus determines a trait (located on the chromosome).
8. ribonucleic acid; a nucleic acid that plays an important role in the production of proteins.
10. Change in a DNA sequence that affects genetic information.
11. A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size.
12. The passing of traits from parents to offspring.
13. A genetic makeup of an organism. The combination of the alleles for a particular gene (Ex: homozygous or heterozygous).
14. A diagram showing the gene combinations that might result from a genetic cross.
18. A strong layer around the cell membrane in plants, algae, and some bacteria.
