Chapter 6-Intro to Metabolism METABOLISM= all the chemical reactions in an organism CATABOLIC PATHWAY (CATABOLISM)• release of energy by the breakdown of complex molecules to simpler compounds EX: digestive enzymes break down food ANABOLIC PATHWAY (ANABOLISM) • consumes energy to build complicated molecules from simpler ones EX: linking amino acids to form proteins ORGANISMS TRANSFORM ENERGY ENERGY- capacity to do work KINETIC ENERGY- energy of moving objects POTENTIAL ENERGY- energy

1/Nastic Movement: "Nastic movements are non-directional responses to stimuli (e.g. temperature‚ humidity‚ light irradiance). The movement can be due to changes in turgor or changes in growth. Nastic movements differ from tropic movements in that the direction of tropic responses depends on the direction of the stimulus‚ whereas the direction of nastic movements is independent of the stimulus. The rate or frequency of these responses increases as intensity of the stimulus increases. An example of

Nutrition in Plants – Mineral Nutrition- essential minerals for plant growth MODULE - 2 Forms and Function of Plants and Animals 9 Notes NUTRITION IN PLANTS – MINERAL NUTRITION Sometimes you may observe that a potted plant kept in sunlight and provided with sufficient water does not grow. Its leaves look pale and weak. Plant may not even flower properly. Such a situation is an indication‚ that the plant may not be getting all that is required for normal growth and development. In most of such

Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

SST 242: PRINCIPLES OF SEED PRODUCTION Lecture Two Title: Vegetative Propagation Introduction Man has propagated plant material almost as long as he has cultivated the land to produce food. For a long time‚ plant material was propagated mainly by using the seeds of existing plants. Better methods were discovered over time‚ methods that allowed the farmer to retain the desirable qualities of the plant material‚ while eliminating some of the less desirable qualities. Through these methods‚ the
