Cell membrane: the outside layer that determines what goes in and what goes out of the cell Cell wall: mostly in plant cells, covers the outside of the cell and acts as protection Cytoplasm: the jelly-like substance floating in the cell Vacuole: acts as a storage tank for food, wastes, and water Mitochondrion: acts as the powerhouse of the cell Endoplasmic Reticulum: transports things around the cell Nucleus: the control center or brain of the cell Chloroplast: contains chlorophyll Similarities between plant and animal cells Plant and animal cells both have membranes, cytoplasm, vacuoles, mitochondrion, and an endoplasmic reticulum, but animal cells don’t have cell walls or chloroplasts.
1. All living things are composed of cells 2. Cells are the basic unit of function and structure of living things 3. All cells come from other cells ScientistDiscovery Cell Theory Robert Hooke Looked at cork; noticed boxes like cells 1 and 2 Anton van Leeuwenhoek Viewed animalcules; first to see bacteria 1 and 2 Matthias SchleidenConcluded all plant parts are made up of cells 1 and 2 Rudolf VischowCells come from existing cells 3
What is the difference between passive and active transport? Passive is when the molecules travel from a higher concentrated area to lower one through different pressures, but active is the same without the pressures. Mitosis Interphase Prophase Metaphase Anaphase Telophase Mitosis is asexual, but meiosis is sexual.
Unicellular: single-celled, one cell Multicellular: more than one cell Respiration: the process of breathing Digestion: breaking down food Excretion: waste Growth: how an organism develops into a adult Reproduction: to produce more of oneself Active Transport: molecules going from higher to lower concentration Passive Transport: molecules going from higher to lower concentration with different pressures

Define osmosis: Osmosis is when a big molecule travels from high concentration to low concentration. Describe what is happening in the picture above: The solute is passing through the barrier and going into a lower concentrated area Define diffusion: Diffusion is when molecules spread or dissolve from a high concentrated area to a lower one. Describe what is happening in the picture above: The red molecules are spreading or dissolving from a high concentrated area to a lower one.
DNA – contains your genetic make-up Gene – a specific trait Allele – pairs of genes Homozygous – pure genotype Heterozygous – different genotype Chromosome – made up of DNA Phenotype – your genes appearance Genotype – the letters of your genes Dominant – the capital letter in a genotype Recessive – the lower-case letter in a genotype Hybrid – different genotype (heterozygous)
DNA is coded instruction that store and pass genetic information from one generation to the next. DNA rungs are made of four sets of nitrogen bases and a backbone of phosphate and sugar. Nitrogen Bases Adenine - Thymine Thymine - Adenine Cytosine - Guanine Guanine – Cytosine
Mendel – father of genetics Watson & Crick – created the 1 st model of DNA; won the Nobel prize Wilkins & Franklin – took pictures of DNA
2 possible phenotypes – yellow and green 3 possible genotypes – YY Yy yy Yy – heterozygous YY, yy – homozygous YY, Yy – dominant/ yy – recessive GreenYellow 2:4 50% ½ 2:4 50% ½ YYYyyy 0% 0 2:4 50% ½ 2:4 50% ½
Taxonomic key: statements that describe the physical characteristics of an organism Dichotomous key: a key that categorizes species Phototroprism: an organism’s response to light Eutrophication: rich nutrients in a lake Succession: predictable changes in a community Dormancy: a state of quiet Hibernation: a state of greatly reduced body activity in the winter

Photosynthesis is the foundation of all food webs. Equation for photosynthesis Reactants: carbon dioxide, water Products: carbohydrates, oxygen
Producer: an organism that makes it’s own food Consumer: an organism that doesn’t make it’s own food Decomposer: an organism that breaks down dead organisms Heterotroph: an organism that eats other things Autotroph: an organism that makes it’s food
Condensation Precipitation Evaporation Sun Ocean Evaporation: when the water turns into water vapor and starts floating upward Condensation: when the vapor turns into clouds Precipitation: the water falls from the clouds
In this cycle, the regular carbon is being turned into alternative fuel by grounding corn.
Producer: grass 1 st consumer: ant 2 nd consumer: spider What is the difference between a food chain and a food web? A food chain only maps 1 path, but a food web shows more than 1 path.

1. B Herbivore 2. E Carnivore 3. C Decomposer 4. D Omnivore 5. A Producer 6. F Consumers A. an organism that can use sunlight in order to produce its own food (autotroph) B. an organism that only eats producers C. an organism that breaks down dead or decaying organisms D. an organism that will eat producers and consumers E. an organism that will only eat other consumers F. an organism that eats in order to obtain energy (heterotroph)
Competition: struggle for limited resources Cooperation: working together Social hierarchy: the chain of importance within a species Territorial imperative: to claim or defend a territory Niche: an organism’s role in an ecosystem Predator: a carnivore that hunts animals for food Prey: the animal that the predator hunts Parasite: an organism that lives on and harms the host Host: a organism that provides a source of energy for a virus
A. Commensalism – one animal benefits and the other is not helped or harmed B. Mutualism – both partners benefit from living together C. Parasitism – one organism live on another harming the other B 1. Plover bird gets food by acting as a toothpick for a crocodile. A 2. The cattle egret eats the insects that are escaping as cattle graze in the field. C 3. A tick sucks the blood from a deer. C 4. A tapeworm in a dog gains energy from the dog but the dog loses nutrition due to the tapeworm. B 5. Ostriches and zebras move together to warn each other of impending danger because the ostrich sees well and the zebra hears well.
Eutrophication: buildup over time of nutrients *phototropism: organism’s response to light *community: all the different populations in one area *population: all the members of one species in one area *biome: a group of ecosystems with similar climates and organisms *ecosystem: all the living and nonliving things that interact in an area *adaptation: a characteristic that helps an organism survive *permafrost: soil that is frozen all year *taiga: a swampy coniferous forest *canopy: a leafy roof formed by tall trees *deciduous: a tree that sheds it’s leaves annually *nocturnal: active at night
