Seth Adler Where Did Agriculture Originate? Began before recorded history. Origins of Agriculture. Agriculture ? Modification of Earth?s surface through cultivation of plants and rearing of animals for sustenance or economic gain. Originated when humans domesticated plants and animals. Crop ? Any plant cultivates by humans. Hunters and Gatherers. Lived in small groups (<50). Large groups would use up more resources. Men hunted and women gathered. Based on archaeology and anthropology, not stereotypes. Kept peace by steering clear of each other?s territory. Less than a quarter million (0.005%) still hunt and gather.

Katie Hallstead Mrs. Legary AP Biology p.0 January 15, 2013 Lab 4: Plant Pigment and Photosynthesis Abstract In this experiment, there are two activities that aim to find two different things. In the first one, paper chromatography is used to separate the pigments found in chlorophyll. The second activity consists of measuring the rate of photosynthesis by observing the change in color that happens when DPIP is reduced through a time interval. Problem How many pigments exist within plants, and at what rates do they photosynthesize when exposed to different lights? Hypothesis

Plant Organs & Organ Systems --roots, stems, leaves Vascular Plant Organs -primary growth *chloroplasts in some green stems but PRIMARILY in the leaves *mitochondria- in all cells Vegetative Parts -roots, stems, leaves -for maintainance of individual, growth -somatic cells Reproductive Parts -flowers, fruits, seeds -maintainance of species *some no flowers, only spores ~PIC1 Root -anchors the plant -absorbs water and minerals -root hairs -brown, white, red, black -no green (few exceptions: orchids) -shape: cylindrical -produce hormones, some for storage ~PIC2 Root Systems ~PIC3 Radicle -first that grows out in germination -will become the primary root *2nd, 3rd, 4th.. root- ?lateral roots? ~PIC4 Patterns of Root Growth Taproot system
