Plant hormones control growth in the shoot apex. Plant shoots respond to the environment by tropisms. Auxin efflux pumps can set up concentration gradients of auxin in plant tissue. Auxin influences cell growth rates by changing the pattern of gene expression.

Experimental setup: Use a potometer to measure the rate of transpiration. Change the different conditions in which the plants are found as well as the species. Independent Variable: Plant species + humidity/temperature/ light intensity Phototropism •Phototropism is the growth of stems of plants toward light - it is probably the best known of the plant tropisms - phototropism is caused by elongation of the cells on the shaded part of the plant - so that entire plant bends or curves toward the light •This growth pattern is caused by the hormone auxin - auxin migrates to the shaded part of the plant and stimulates increased cell growth and elongation on the shaded part of the plant IAA = Auxin 9.3 U.4 Plant shoots respond Topic 9: Plant biology: 9.1 Transport in the xylem of plants: 9.2 Transport in the phloem of plants: 9.3 Growth in plants: 9.4 Reproduction in plants: Topic 10: Genetics and evolution: 10.1 Meiosis: 10.2 Inheritance: 10.3 Gene pools and speciation: Topic 11: Animal physiology: 11.1 Antibody production and vaccination: 11.2 Movement: 11.3 The kidney and osmoregulation Plant Structure and Growth - Modifications, Phototropism (IB Biology)Table of Contents:00:00 - Root, stem and leaf modifications02:25 - Apical and Lateral Me Se hela listan på blog.prepscholar.com Share your videos with friends, family, and the world [DOWNLOAD] Ib Biology Plant Exam Questions And Answers .
