Hypertonic | Water is pulled out of the cell, shrinks |
Cohesion | Water sticks to water |
Adhesion | Water is attracted to different substances |
Enzyme | Lowers activation energy for chemical reactions |
Carbohydrate | Short term storage (monosaccharides, simple sugar) |
Protein | Control chemical reactions, structure, fights diseases (amino acids) |
Lipid | Long term energy storage, main molecules of membranes (1 glycerol, 3 fatty acids) |
Nucleic Acid | Instructions for protein synthesis, pass on genetic info (nucleotides) |
Haploid | Half # of chromosomes |
Diploid | Full set of chromosomes |
Chromatin | -- |
Chromatid | -- |
Mitosis | Split one cell into two identical cells - asexual reproduction |
Meiosis | Split one cell into four cells with half the chromosomes - gametes: eggs and sperm |
Interphase | -- |
Prophase | -- |
Metaphase | -- |
Anaphase | -- |
Telophase | -- |
Anaerobic respiration | Does NOT use oxygen, occurs in cytoplasm, produces 2 ATP (alcohol fermentation) |
Aerobic respiration | Uses oxygen, occurs in mitochondria, produces 36 ATP |
Cellular respiration | Breaks down food for ATP |
Endocytosis | Moves particles into the cell |
Exocystosis | Moves particles out of the cell |
DNA replication | Occurs in the nucleus of the cell, results in an exact copy of the original strand |
Transcription | Occurs in the nucleus, makes mRNA copy of the gene |
Translation | mRNA is translated into a chain amino acids |
Classification | DKPCOFGS |
Viruses | DNA or RNA strand, surrounded by a protein coat |
Viruses are different from bacteria bc- | They are not alive, cannot reproduce, are not cells |
Bryophyte | Depends on water for reproduction, small, lack vascular tissue (Moss, Liverworts, Hornworts) |
Seedless Vascular | Ferns, Horsetails, Club mosses |
Gymnopserm | Produce seeds on cones (Gnetophytes, Cycads, Ginkos, Conifers) |
Angiosperm | Produce seeds from flowers (eggs and pollen are reproductive organs) |
Porifera | Eukaryotes, specialized cells, pulls water in through pores (sponges) |
Cnidaria | Soft body, specialized tissues, tentacles with stinging cells (hydra, jellyfish, sea anemone, corals) |
Platyhelminthese | Flatworms |
Nematoda | Roundworms |
Annelida | Segmented worms (earthworms, leeches, neries, feathery things) |
Molluska | Soft body, internal or external shell, reproduces sexually (clams, squids) |
Arthropoda | Exoskeleton, jointed legs, metamorphosis (crabs, insects) |
Echinodermata | Spiny skin, tube feet, radial symmetry, internal skeleton (starfish) |
Charles Darwin | Theory of Natural Selection |
Low power objective | Magnifies 10x |
High power objective | Magnifies 40x |
Fine adjsutment | Fine focuses |
Coarse adjustment | Fines object in low power/focus |
Diaphragm | Change light level |
Eye piece | Sees object, magnifies 10x |
Polarity | Electrons are more attracted to the larger oxygen atom in the water molecule so oxygen is slightly negative and hydrogens are slightly positive. |
Parasitism | One organism benefits, the other is harmed |
Commensalism | One organism benefits, the other is unaffected |
Mutualism | Both organisms benefit |
Centrioles | -- |
Cell membrane molecule | Double lipid layer, protein, carbohydrate |
Photosynthesis formula | 6CO2 + 6H2O + light energy = C6H12O6 + 6O2 |
Difference between photosynthesis and respiration | Photosynthesis stores energy, respiration releases ATP from food |
Adaptation | Characteristics that help organisms survive in their environment |
Lamarck | Theory of Acquired Traits |
Transpiration | Evaporation off of plant leaves |
Detritivore | Animal that feeds off of dead organic material |
Primary succession | No soil after disturbance |
Secondary succession | Community is disturbed but soil still exists |
Pioneer species | Lichen and bacteria |
Population density | Number of individuals living in a unit of area |
Carrying capacity | Largest number of individuals an environment can support |
Exponential growth | Growth under the ideal conditions with reproduction at a constant rate |
Cell theory | All living things are made of cells, cells are basic units of life, all cells are produced from other cells |
Principle of dominance | When you cross 2 different true breeding alleles one characteristic will cover up the other one |
Incomplete dominance | A heterozygote shows a mixture of the 2 characteristics, neither gene is dominant (red + white = pink) |
Codominance | A heterozygote shows both characteristics |
Chargaff's rules | -- |
Genetic engineering | -- |
Evolution | -- |
Natural selection | -- |
Directional selection | Individuals at one end of the curve survive better |
Stabilizing selection | Organisms survive better near the center of the curve |
Disruptive selection | Organisms at both end survive better |
Binary fission | Asexual reproduction (bacteria) |
Lytic infection | -- |
Miller and Urey | -- |
Hooke | First to see cells (cork) and to name them "cells" |
Van Leeuwenhoek | Discovered bacteria or "protozoa" and made the first microscope |
Schleiden | Found that all plants are made of cells |
Schwann | Found all animals are made of cells |
Virchow | Found that all cells come from existing cells |
High heat capacity | -- |
Surface tension | A measure of how difficult it is to stretch or break the surface of a liquid |
