Bioethanol |
Type of alcohol produced by the fermentation of glucose |
|
Cellulosic Ethanol |
Type of bioethanol made from cellulose in nonedible plant material such as wood or grass. |
|
Biodiesel |
Made from plant oils or recycled frying oil. |
|
Stomata |
(Mouth) Underneath side of the leaf, tiny pores in the leaves. They take in carbon dioxide and oxygen exits. |
|
Thylakoids |
Inside chloroplasts are interconnected, membranous sacs. |
|
Grana |
Thylakoids are concentrated in stacks. |
|
Chlorophyll a |
Absorbs mainly blue-violet and red light. Participates directly in light reactions. |
|
Chlorophyll b |
Absorbs mainly blue and orange light. Participates directly in the light reactions. |
|
Cartenoids |
Absorbs blue-green light. Participates INDIRECTLY in the light reactions. Passes energy to chlorophyll a. |
|
Wavelength |
The distance between the crests of two adjacent waves. |
|
Electromagnetic Spectrum |
Full range of radiation. |
|
C3 plants |
Use Carbon Dioxide directly from the air. Are very common and widely distributed. |
|
C4 plants |
Close their stomata to save water during hot and dry weather. Can still carry out photosynthesis by storing and transferring Carbon Dioxide to adjacent cells. |
|
CAM plants |
Are adapted to very dry climates. Open their stomata only at night to conserve water. |
|
Parthenogensis |
Eggs develop without fertilization, "virgin creation". Reproduction without sex. |
|
Asexual Reproduction |
Single-celled organisms reproduce by simple cell division. No fertilization of an egg by a sperm. |
|
Sexual Reproduction |
Fertilization of an egg by a sperm. |
|
Chromatin |
Unwound DNA. |
|
Histones |
Are proteins used to package DNA in eukaryotes. |
|
Cell cycle |
The ordered sequence of events that extent from the time a cell is first formed from a dividing plant cell to its own division of cells. Two distinct phases. |
|
Mitosis |
Nucleus and its contents divide evenly into two daughter nuclei. |
|
Cytokinesis |
Cytoplasm is divided in two. |
|
Tumor |
Abnormally growing masses of body cells. |
|
Metastasis |
The spread of cancer cells beyond their original site. |
|
Diploid |
Organisms with body cells containing two sets of chromosomes. |
|
Haploid |
Gametes that have only one member of each homologous pair of chromosomes. |
|
Sex Chromosomes |
Male=XY ; Female=X |
|
Autosomes |
22 pairs of matching chromosomes. |
|
Karyotype |
Image that reveals an orderly arrangement of chromosomes. Homologous chromosomes - matching pairs of chromosomes that can possess different versions of the same genes. |
|
Law of Independent Assortment of Chromosomes |
Chromosomes align independently of each other. |
|
Nondisjunction |
Members of chromosomes don't separate. Happens in Meiosis 1 and 2. |
|
Trisomy 21(Down's Syndrome) |
Individual has an extra chromosome 21. |
|
RuNP |
5 carbon in the Calvin cycle, taking place during photosynthesis. Gets turned into G3P. |
|
G3P |
Unstable molecule created by RuBP |
|
Heredity |
Transmission of traits from one generation to the next. |
|
Genetics |
The scientific study of heredity. |
|
Gregor Mendel |
Father of modern genetics. First person to analyze patterns of inheritance, and deduced the fundamental principles of genetics in the 1860s. |
|
Character |
Heritable feature that varies among individuals. |
|
Trait |
Variant of a character(blue, green, brown, hazel) |
|
Allele |
Trait, refers to the generic version. Alternate versions of a gene, one from each parent. |
|
Homozygous |
Both alleles are identical. Homozygous dominant(BB) |
|
Dominant |
BB |
|
Recessive |
Bb |
|
Heterozygous |
Alleles are different(Bb). |
|
Law of segregation |
Anaphase in meiosis. Alleles separate from each other during the production of gametes. |
|
Phenotype |
Physical appearance |
|
Genotype |
Genetic makeup |
|
Punnett Square |
Diagram that shows the results of a genetic cross. |
|
Monohybrid Cross |
The mating of two parental varieties with one heritable character. |
|
Dihybrid Cross |
Mating of two parental varieties differing in two characters. |
|
Law of independent assortment of alleles |
Alleles separate independently. The inheritance of one character has no effect on the inheritance of another. |
|
Gene Locus |
Specific location of a gene along a chromosome. |
|
Test Cross |
Mating with a homozygous individual. |
|
Wild type traits |
Seen most often in nature. |
|
Pedigree |
Shows history of a trait in a family and allows geneticists to analyze human traits. |
|
Carrier |
Heterozygous genotype(Ff). Individuals who have the recessive allele but appear normal. |
|
Inbreeding |
Mating of close relatives. |
|
Incomplete dominance |
Appearance between the phenotypes of the two parents. |
|
Codominance |
AB. Both alleles are expressed in heterozygous individuals who have type AB blood. |
|

(Stimulate many). One gene influences several characters. |
|

Two or more genes on a single phenotype(height, eye color, hair color). |
|
Linked genes |
Goes against Mendel's Law of Independent Assortment. Close together on a chromosome, inherited together. |
|
