Chapter 29 An Overview of Land Plant Evolution 1. Describe four shared derived homologies that link charophyceans and land plants. a. The complexes that produce cellulose are rose shaped in both charophyceans and land plants. Next both have peroxisome enzymes that help minimize the loss of organic products from photorespiration. The structure of their flagellated sperm is very similar. Finally‚ both form a phragmoplast during cell division. 2. Distinguish among the kingdoms Plantae‚ Streptophyta

Sphincter-they BOTH prevent the flowback of the food but each one of them performs a very important function.

AP Biology notes: Chapter 2- The Chemical Context of Life 1. Overview * The bombardier beetle fights the ants that plague it by using chemistry. * The natural systems and environment that organisms live in involves chemistry and physics. * Biology is not the only category of science. There is also chemistry‚ physics‚ and engineering. * Organization of life is separated into a hierarchy of structural levels. 2. Elements and Compounds * Matter- anything that takes up

Chapter 1: Introduction to Human Geography * Fieldwork- go out in the field and see what people are doing‚ observe how people’s actions and reactions vary across space * Summary of Field Note: Kenya full of fertile farmland but many are hungry. Why don’t they grow food for themselves? Most of Kenya is owned by foreigners and Kenya needs the foreign revenue * Human geography- how people make places‚ how we organize space and society‚ how we interact with each other in places and across

Spodek Guided Notes Chapter 1 A. The Dry Bones Speak I. Human Origins in Myth and History - Paleoanthropology - A student of the earliest humans and the setting in which they lived. - Humans all over the world made stories to explain origin (Before diggers came with interpretations and cussing). o They tell how and why humans came to Earth. a. Early Myths - Myth – An interpretive story of the past that cannot be verified historically but has a deep moral message. - Caste – Social‚ economic

after speciailisation. (That is TOTALLY spelt wrong.) Oestrogen: 1. The DNA binding site on a Transcription Factor (the thing that stimulates transcription)‚ can sometimes be inhibited 2. Oestrogen is lipid soluble and passes through the cell surface membrane easily 3. It binds with the receptor of the transcription factor. 4. This changes the same of the whole molecule‚ including the DNA binding site. 5. The Inhibitor is subsequently‚ removed. 6. The Transcription factor

Characteristics of hydrophytes: 1. A thin cuticle. Cuticles primarily prevent water loss‚ thus most hydrophytes have no need for cuticles. 2. Stomata that are open most of time because water is abundant and therefore there is no need for it to be retained in the plant. This means that guard cells on the stomata are generally inactive. 3. An increased number of stomata‚ that can be on either side of leaves. 4. A less rigid structure: water pressure supports them. 5. Flat leaves on surface
