Plant Physiology - Transportation Questions and Answers

Water can be pushed out of capillaries by ________ while also drawn into the capillaries by _______. osmosis; blood pressure blood pressure; osmosis oncotic force; hydrostatic force blood pressure; diffusion

Which of the following is responsible for the cohesive property of water? Hydrogen bonds between the oxygen atoms of two adjacent water molecules Covalent bonds between the hydrogen atoms of two adjacent water molecules Hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule Covalent bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule Hydrogen bonds between water molecules and other types of molecules

If ATP breakdown (hydrolysis) is inhibited, which of the following types of movement across cell membranes is also inhibited? (A) Movement of oxygen into a cell (B) Movement of water through aquaporins (C) Passage of a solute against its concentration gradient (D) Facilitated diffusion of a permeable substance

When the cell concentrates potassium within, against the natural tendency of matter, it is performing passive diffusion facilitated diffusion active transport pinocytosis

You are given the following task: Use gummy bears to prove you understand the basics of osmosis and diffusion. Here are the materials you have to work with: • A bag of 10 clear-colored gummy bears. Each gummy bear is 70% sugar and 30% water. • Three equal sized containers. • Water • Sugar • Mystery Solution (unknown percentage of sugar and water) • Purple dye • A scale (to measure the weight of the gummy bears) Your must first weigh the gummy bears. You find that each gummy weighs 4.5 ounces. Your directions tell you that you must prepare a solution that will make the gummy bears gain weight. Which of the following solutions would be the best choice to cause the gummies to gain the most weight? NOTE - This brand of gummy bear will NOT dissolve in the water. Only water and very small ions (NOT sugar) will move into or out of the gummy bear.

Which of these provides an example of molecules moving by facilitated diffusion? A)Water diffuses across the phospholipid bilayer with the gradient. B)Na* moves through a membrane protein against the gradient to the cytoplasm. C)O₂ moves from high concentration outside the blood cell to low concentration inside the blood cell. D)Glucose moves from high concentration in the blood to lower concentration in the cell using a membrane protein.

The property of some metabolic pathways that enables them to serve multiple functions in the breakdown, synthesis, and conversion of metabolites is known as amphibolism catabolism beta oxidation chemiosmosis

Answer the following transport questions. a. Define Passive transport and distinguish between Facilitated Passive Transport (Facilitated Diffusion) and Simple Passive Transport (Simple Diffusion) b. Define Active Transport and distinguish between Primary Active and Secondary Active

Receptor-mediated endocytosis brings in specific material by engulfing it in vesicles. What factors, either directly or indirectly, are related to this process? Choose all that apply. It is a passive process. It helps to increase membrane fluidity by helping to transport cholesterol into the cell. It is an active process. It uses carrier proteins.

Active transport requires energy. O True O False

The conducting tissue found in vascular plants that functions in transportation of nutrients throughout the plant and is made of living sclerenchyma and parenchyma cells is the O endosperm. O xylem. O sporopollenin. O lycophyll. O phloem..
