Bio 115 Exam 1 Study Guide These topics will be on the exam. ▪ What are the tenets of cell theory? • Cells are the basic structural and physiological units of all living organisms. • Cells are both distinct entities and building blocks of more complex organisms. OR • All living organisms are composed of one or more cells‚ Cells are the basic units of structure and function in an organism‚ and Cells come only from the reproduction of existing

ay from printed circuit boards (PCBs) that used copper containing thick- lm pastes on rigid substrates‚ which were patterned using a two-step masking and etching process. This process resulted in a surfeit of waste and was expensive due to laborintensive processing of the nal device. By contrast‚ conductive inks are now available that use existing printing technologies such as screen‚ gravure‚ exographic‚ offset‚ and inkjet to print conductive traces directly onto rigid and exible substrates relatively

Study Guide for Quiz 1 What is gastrulation? What layers are formed during this process? The process in which a gastrula develops from a blastula by the inward migration of cells. Goes from one layer to three. Endoderm Mesoderm Ectoderm What is a chimera? a single organism that is composed of two or more different populations of genetically distinct cells that originate from different zygotes involved in sexual reproduction Understand the types of injuries/assaults an early embryo can

Chapter 37: Water and sugar transport in plants Water moves from areas of high water potential to areas of low water potential. Water’s potential energy in plants is a combination of (1) it’s tendency to move in response to differences in solute concentration and (2) the pressure exerted on it Plants do not expend energy to replace water that is lost to transpiration when stomata are open and photosynthesis is occurring. Instead‚ water moves from soil and roots to leaves long a water potential

then into the stomata‚ to the mesophyll cells‚ next to the stoma‚ then finally into the atmosphere. Osmosis is the diffusion of water through semipermeable membranes. Transpiration is the evaporation of water from the leaf. Cohesion is when water molecules stick together. Adhesion is when water molecules stick to‚ not attract. Root pressure is force made by root on water columns. Water potential is the negative pressure in leaves‚ which is positive in roots. 60. a) Flowers are developed in order to
