Title Instructions / Description Sample Puzzle Hints Difficulty
Ecology Living or once living parts of an organisim's habitat. The relation betwen two different organisims where one benifits. All living and non-living organisims in an area and the non-living features in an enviroment.. The relation of two in which one gets food or other benifits from the other.. A place where an organisim lives and has food,shelter,moistere, and temputre needed for survival. Hard
Ecosystem One organism benefits and the other is harmed. Path that energy takes. All living and nonliving things in an environment. No longer exists on Earth. Organisms that are eaten by other animals. Older Children
Molecular Genetics the RNA that makes up ribosomes. nitrogenous base that replaces thymine in RNA. Discovered that DNA was the 'transforming factor' . loosely organized DNA. tightly coiled DNA . Hard
Organic Molecules & Enzymes when an enzyme no longer works because its shape is wrong . monomer of nucleic acids made up of a 5-carbon sugar. the highest point that the temp.. used for stored energy and cell membranes; made of fatty acids. protein that acts as biological catalyst. Hard
Bacteria organisms that can help or hurt your body. make more than one of. a third possible shape of bacteria; a special type of staircase. composing of only one cell. another possible shape o bacteria. Older Children
Biotechnology & Genomics Study of the sequence of DNA bases and the amount of genes in organisms.. DNA that has been synthesized from mRNA by the action of reverse transcriptase. Study of whole genomes. Technique that uses the enzyme DNA polymerase to produce millions of copies of a particular piece of DNA . Repetitive DNA sequence in which the repeats occur one after another in the same region of a chromosome.. Very Difficult
The cell A plastid containing chlorophyll, the site of photosynthesis. stores water and nutrients for the cell; very large in plant cells. a group of similar cells that carry out a similar function. That portion of the endoplasmic reticulum that is free of ribosomes. This says that all living things are made of cells, that cells are the basic unit of structure and function and that cells only come from other cells.. Hard
Heredity a trait that shows up most often in reproduction. the different forms (dominant or recessive) of genes. the different features in a population (i.e. red hair, blond hair). chart used to determine the probability and results of a hybrid cross. the passing of genetic traits from parent to offspring. Hard
Symbiosis A type of symbiosis in which one species benefits and the other is harmed. A situation where symbiosis is not needed. A type of symbiosis in which one species benefits and nothing happens to the other one. The species that is harmed in parasitism. A situation in which both species would die without symbiosis. Hard
Cell Structure produces energy for the cell. stores food water waste. cells that perform the same function. basic unit of structure. life from non living sources. Hard
The Cell Cycle The second phase of Mitosis, the nuclear membrane disappears completely. The spindle fiber fully develops and attach to the centromeres of the chromosomes. Also, the chromosomes align at the center of the cell.. The Midpoint on a chromosome where the spindle fibers attach during cell division.. The combination of DNA and proteins that make up the contents of the nucleus of a cell.. A contains the replicated DNA of each individual chromosome.. The third step of Mitosis, During this time, the cell's centromeres divide and it's spindle fibers shorten. The chromatids separate and move to the opposite sides of the cell. The separated chromatids are now called chromosomes. . Hard
Cells In plants, this organelle is very large. They are storage areas for food, water or waste.. This organelle is the outer part of the nucleus and has little pores to let good things in and keep bad things out.. The DNA strands that float inside of the nucleus.. These tiny organelles make proteins.. This organelle is the center of the cell and acts as the 'brain.'. Hard
Genetics Chromosomes that determine gender of individuals. The scientific study of heredity. Different forms of a gene. Allele whose trait is hidden by dominant allele. Offspring of the P1 parents, have only one of the two parental traits. Hard
Cell Biology and Culture single celled organisms. stores materials in a cell. Make up proteins. Source of stored energy and insoluble in water. . All of an organism hereditary information.. Very Difficult
Energy & Life The region outside of the thylakoid membranes.. It is the membrane that contains a protien.. Light absorbing molecules.. It is a principal chemical compound that stores energy.. Requires light, and make oxygen gas and convert ATP and NADP+ intpo energy carriers A+B and NAPH.. Hard
Biology Life on Earth: Plants an early stage development for an organism. provides food for the embryo. a reproduction system that switches back and forth. a process of change between two organisms. primary plant root. Hard
Cells Site of photosynthesis. The cell walls of fungi are made up of this. Storage blob in plant cells. Type of fermentation used in muscle cells: ______ acid. Macromolecule made of fats and oils. Hard
Cell uses energy from the sun to make food for plants with the process of photosynthesis. . store food water metabolic and toxic wastes.. controls movement of materials in and out of nucleus.. packages and exports proteins.. strengthen the cell and maintains the shape.. Hard
