Mica Piro Chapter 36: Resource Acquisition & Transport in Vascular Plants Adaptations for acquiring resources were key steps in the evolution of vascular plants (36.1) EVOLUTON Land plants typically inhabit 2 worlds?above ground (where shoots acquire sunlight and CO2) and below ground (where roots acquire water and minerals) The algal ancestors of land plants absorbed water, minerals, and CO2 directly from the water in which they lived Earliest land plants were nonvascular plants that grew photosynthetic shoots above the shallow fresh water in which they lived The leafless shoots had waxy cuticles and few stomata, which allowed them to avoid excessive water loss while still permitting some exchange of CO2 and O2 for photosynthesis

Campbell's Biology, 9e (Reece et al.) Chapter 7 Membrane Structure and Function Membranes and membrane transport are fundamental to cellular life. The concepts in this chapter require integration of concepts from previous chapters: the nature of water and hydrophobic versus hydrophilic molecules, the properties of lipid molecules and their role in regulating membrane fluidity, and the roles of proteins and carbohydrates in membrane function. The concepts of ion transport and electrochemical gradients across membranes are important foundations for the following chapters on energy metabolism. Finally, the bulk transport phenomena have important clinical significance in the immune system, during invasion by pathogens, and in cell signaling. Multiple-Choice Questions

Chapter 7 A View of the Cell The Discovery of Cells The History of the Cell Theory The first person to record looking at water under a microscope was Anton van Leeuwenhoek. Robert Hooke used a compound light microscope to study cork, the dead cells of oak bark. Matthias Schleiden studied plants under a microscope and concluded that all plants are made of cells. Theodore Schwann studied animal cells and concluded that all animals are made of cells. Rudolf Virchow hypothesized that cells divide to form new cells & all cells come from preexisting cells The Cell Theory: All organisms are composed of one or more cells. The cell is the basic unit of organization of organisms. All cells come from preexisting cells.

All of the following are part of a prokaryotic cell except a. DNA. b. a cell wall. c. a plasma membrane. d. ribosomes. e. an endoplasmic reticulum. 2. The volume enclosed by the plasma membrane of plant cells is often much larger than the corresponding volume in animal cells. The most reasonable explanation for this observation is that a. plant cells are capable of having a much higher surface-to-volume ratio than animal cells. b. plant cells have a much more highly convoluted (folded) plasma membrane than animal cells. c. plant cells contain a large vacuole that
