Parts of an experiment control group, variable group, control constant, variable constant, independent variable, experimental group
6 characteristics of a living thing Living things are made of cells. Living things obtain and use energy. Living things grow and develop. Living things reproduce. Living things respond to their environment. Living things adapt to their environment.
Estimate mass of pencil, laptop, and a car pencil- 5 grams laptop- 1 kilogram car- 1 ton
Estimate length of a white board, textbook, an a paperclip. whiteboard- 1.5 meters textbook- 30 centimeters paperclip- 1 centimeter
Anton Van Leeuwenhoek Dutch lens maker, 1st person to observe living cells
Charles Darwin Natural selection theory made by him. " Father of evolution"
Gregor Mendel Made idea of dominant and recessive traits, studied pea plants
Francesco Redi Said spontanious generation is not true, tested with meat in jars to prove it.
Steps of using a microscope Plug it in and turn it on, place slide in stage clips with the object locked in place. Move the stage all the way up. !st focus on medium power an then try high. Only use fine adjusment on high power
Know 7 major biomes, their climate, and give examples o organisms that live there. Tundra, temperate deciduous forest, grassland, tropical rain forest, desert, boreal forest, and coniferous.
Cell theory Cell is the basic unit of life, Cells are the basic units of structure and function in living things. Living cells come only from other living cells. By Anton V. Leeuwenhoek
How are organisms classified similaraties, how it grows, classification groups
Classification groups Kingdom, Phylum, Class, Order, Family, Genus, Species
Scientific names genus and species
Monera unicellular, no nucleus, bacteria
protista uni or multi cellular, nucleus, amoebas
fungi uni or multicellular, plant like, get food from dead org., yeasts and fungi, cell walls, grow in soil, fermentation, spore to reproduce.
plantae multicellular, photosynthesis, plants trees
animalia multicellular, eats other organisms, birds, mammals, reptiles, fish, amphibians
sporulation asexual, new org. forms from spores released from parent
budding asexual, new org. forms from bud on parent
fission parent splits into two
3 groups of protists Protozans-unicellular, cant make own food, amoebas, paramecium, typanosomes Algae- uni/ multi cellular, have chlorophyl, photosynthesis, plankton, euglena, seaweed slime molds- multicellular, in soil or lakes, some are paracites, slime molds, water molds
Bacteria Monera, have cytoplams, cell membrane, cell wall, asexual, use flagellum, need water or oxygen to survive.
How are bacteria classified? shape. Cocci, spirilla, bacilli
formula for photosynthesis 6CO2 + 6H2O ------> C6H12O6 + 6O2 or Carbon dioxide + water equals to glucose and oxygen
tropism turning movement of an organism in response to an environmental stimulus.
vegetative propagation asexual reproduction of a plant
bryophytes no transport tubes
tracheophytes have transport tubes
Poriferans huge pores and seems to be boneless, invertebrate, sponges
cnidarians 2 cell layers, radical symmetry, have tentacles or stinging cells, 1 body opening, jellyfish
arthropods have crustaceans, arachnids, and insects, invertebrates, have exoskeletons, antennae on insects. lobsters, spiders, ant, flies, shrimp, crab, scorpians
platyhelminthes some paracitic flat, can split, live in fresh water, 2 eye spots, planeria
Nematods worm with round body, live in soil or water, paracitic, hookworms
annelids little rings/ segments, complex, ocean or fresh water, earthworms
mollusks soft body, mantle, shell, snails and slugs, mollusk w/ tentalces
genetics study of heridity
heridity passing traits from parent to offspring
Types of movable joints pivotal joint-side to side, up and down. ball & socket-all directions gliding - some movement hinge- fowards and backwards
4 tissue types muscle- attached to bones, makes them move epithenal- cowers body connective- connects tissue nerve- carries messages, makes tissues move
Nerve impulses messages
reflex arc pathway of message in reflex
how does blood move from body with transport tubes
3 types of blood vessels arteries-strong thick walls, tubes from heart cappilaries-blood cells exchange nutrients and waste in these veins- push blood flowing, have valves.
3 parts of respiration external- getting oxygen internal-exchange of co2 and oxygen cellular-energy is relesed by cells, food is converted into energy w/ oxygen
male reproductive organs urethra in penis, testes-produces sperm, bladder,scrotum- sac that holds testes outside of body, epidermis-where sperm mature, and are stored
female reproductive organs ovaries- produces eggs, uterus- nurtures fetus, fallopian tubes-tubes from ovaries to uterus, cervix-opening of uterus, vagina-birth canal
