PPT-9.3 Growth in plants

Plants adapt their growth to environmental conditions Undifferentiated cells Undifferentiated cells in the meristems of plants allow indeterminate growth Meristems are tissues in a plant consisting of undifferentiated cells capable of indeterminate growth . Ascend plant growth regulator contains an optimum combination of three plant growth regulators and can be used as a seed treatment in furrow or as a foliar application Ascend plant growth regulator can also be applied by ground air or chemigation Pl Mariposa Master Gardener. Helen Willoughby-Peck. Cloning or Asexual. After seeds, stem cuttings are the most widely used form of plant propagation . . Types of cuttings. Choosing . plant material. Topic 9.3. U: . Undifferentiated cells in the meristems of plants allow indeterminate growth. Most plants . have indeterminate growth . = cells divide indefinitely (most animals have . d. eterminate growth). Roots. , Stems, and Leaves. Reproduction . in Flowering . Plants. Plant . Characteristics. Plants come in all sizes, from the tiny duckweed which grows to only about 10 mm in length, to the giant redwood which grows to about 100 m in height.. There are great numbers of Bonsai plants species are available on earth. You can see different sizes of tropical and sub-tropical species. Each one of them requires the diverse environment to survive and other requirements of those healthy growths. Some popular species are discussed below Plants= eukaryotic, . multicellular, . photosynthetic. . Green Algae. Bryophytes. (Non-vascular). Tracheophytes. (Vascular). Non-seeds. Seeds. Gymnosperms. (Naked seeds). Angiosperms. (Seeds in flowers and fruit). Nonvascular plants. have no vessels, no roots, no stems or leaves. Examples: Mosses & Liverworts. Vascular Tissue. Xylem: transports water. Phloem: transports food & nutrients. Gymnosperms. "naked seeds". Plants= eukaryotic, . multicellular, . photosynthetic. . Origin of Land Plants?. Evidence that Green Algae are the ancestors. 1) DNA. 2) Ch a & b. 3) True starch inside chloroplasts. 4) Diverse life cycles & reproduction. FLORIDA PLANTS What is a native plant? Plants native to Florida are plants that were here before the arrival of the Europeans Plants native to this area of Florida have evolved mechanisms over the centuries that enable them to handle our climate. Chapter 26. Control of Plant Development. plant hormones. chemical messengers within organisms. each has a very specific function . auxins. promote growth at apical . meristems. cause growth in different directions. For a small area prepare the soil by loosening it with a fork spade or roto-tiller Make a planting hole wider and deeper than the largest root Hold the transplant at the proper depth see ROOT EXAMPLE Phytohormones. :-. (. i. ) Growth hormones also called . phytohormones. (ii) Term given by . Thimann. (1948),. (iii) It can be defined as ‘the organic substances which are synthesized in minute quantities in one part of the plant body and transported to another part where they influence specific physiological processes’.. Growth Responses. Lecture Outline. 1. Outline. 26.1 Plant Hormones. 26.2 Plant Responses. 2. 26.1 Plant Hormones. Flowering plants respond to environmental stimuli such as:. Light, gravity, carbon dioxide levels, pathogen infection, drought, and touch.. archegonium. which includes bryophytes, . pteridophytes. and gymnosperms. The name of this group is derived from the name of female reproductive organ known as . archegonium. (singular) archegonia (plural). The archegoniate plants comprises the following groups .
