16 March New section begins today. PLANTS I would like you to write down what you know about plants. Your answer should include where they occur, what forms they take, and 5 ways that make them important. Next, draw a plant. It can be big or small and you can draw it with or without flowers. When you are done, think about how water enters and leaves the plants and what the purpose of leaves, roots, stems, and flowers are for. 17 March Define the following words: Vascular plants – plants with water and nutrient conducting cells/tissue. All higher plants, trees, shrubs, and ferns. Non-vascular plants – plants without organized tissue to conduct water and nutrients – moss, algae, and other protista. Xylem – Phloem – Sepal Petal Stamen Carpel Ovary 18 March What are living tissues? look up living tissue on your electronic devices and make a list with the person next to you. If you want to look at animal tissues that is fine, but we are interested in plants today. Using the illustration on page 642, figure 21.2, draw that plant. Label the “dermal”, “ground”, and “vascular” tissue. What is the purpose of each? Describe their purpose in your notes. Vascular plants – plants with water and nutrient conducting cells/tissue. All higher plants, trees, shrubs, and ferns. Non-vascular plants – plants without organized tissue to conduct water and nutrients – moss, algae, and other protista. Xylem – Phloem – Sepal Petal Stamen Carpel Ovary What are the purposes of the petals, carpel, and stamen? 18 March https://www.youtube.com/watch?v=FiFA3lRFxjk Bill Nye Video on Plants 30 March http://www.pbs.org/wnet/nature/what-plantstalk-about-video-full-episode/8243/ What plants talk about PBS special Questions: 1) Describe 6 different examples of how different species in an ecosystem interact with one another. 2) List 3 ways in which wild tobacco defends itself against herbivores 3) List two behaviors that some plants exhibit that are similar to animal behaviors. 1 April Study Guide Questions: Pages: 210 – numbers 6, 7, 9 through 12 211 – all questions 212 – numbers 8, 10 through 13 215 – all questions 216 – all questions 221 – all questions 222 – 4, 6, 7 2 April Today’s objective is to review the plant tissues, parts of a plant leaf, and parts of a flower. You should be able to understand the structure and biological function of each part. Explain how the following plant organs and tissues are directly related to these four physiological processes: (Physiology – the scientific study of function in living systems) Photosynthesis Leaves Stomata Guard cells Stems Phloem - Cellular - Transpiration Respiration Leaves Leaves Stomata Stomata Guard cells Guard cells Stems Roots Xylem - Reproduction Flowers Fruits Cones/Seeds Stamen: Anther Filament Pistil Stigma Style Ovary Stigma Style Anther Filament Petal Carpel Ovary(s) Sepal https://www.youtube.com/watch ?v=26oq5tWrb2Q Pollination video Dicot Stem Dicot Root Monocot Root Plant tissues are made of three basic cell types. Parenchyma cells are the most common plant cell type. • store starch, oils and water • found throughout plant • can divide throughout life • help heal wounds to the plant • have thin flexible walls Collenchyma cells provide support to a growing plant. – they are strong and flexible. – celery strings are strands of collenchyma. – they have unevenly thick cell walls. Sclerenchyma cells are the strongest plant cell type. – second cell wall hardened by lignin – die when they reach maturity – used by humans to make linen and rope Plant organs are made of three tissue systems. 1) Dermal tissue covers the outside of a plant. • protects the plant • made of live parenchyma cells in non-woody plants • some covered by waxy cuticle • dead parenchyma forms outer bark of trees 2) Ground tissue is found inside a plant. • provides support • stores materials in roots and stems • packed with chloroplasts in leaves • most commonly made of parenchyma 3) Meristematic/Vascular tissue transports water, minerals and organic compounds. • makes up xylem and phloem • xylem transports water and minerals • phloem transports photosynthetic products stem leaf root Internal leaf morphology https://www.youtube.com/watch?v=zHp_voyo7MY Plant anatomy – bozeman video SCHS IB Academic Honesty Policy HONESTY and INTEGRITY form the cornerstone of the International Baccalaureate (IB) Honor Code at Spruce Creek High School, and as such are central to the high standards by which all students should live. The IB Honor Code begins with the belief that every student has the right to pursue an education free from the ills caused by any form of intellectual dishonesty. I understand that the IB course of study is difficult, and while group study is both accepted and encouraged, ethical conduct is expected at all times. Academic violations of the Honor Code consist of the following: CHEATING includes the actual giving or receiving of any unauthorized aid or assistance on any form of any academic work. PLAGIARISM includes the copying of or representation of another’s idea or work as one’s own. INHERENT in this Code is the responsibility of an individual to come forth and report any form of violation in the Honor Code. Violations of the Honor Code will be handled in accordance with written teacher policy and considered a disciplinary matter to be generally handled as follows:
