1. Ch. 6 Introduction to Plants Table of contents: Intro. to Plants Bellwork: 1.In your own words define Photosynthesis. 2.What level of the food web are plants located? You have 5 minutes from the bell to start class…..

2. Bellwork Photosynthesis – plants use light energy from the sun to make their own food from the carbon dioxide they get from the air and water the absorb from the soil. Plants are the base level of the food web and energy pyramid. They are known as producers, because they make their own food.

3. Ch. 6 sect. 1 Draw the diagram to the right into your compbook. There are crayons and colored pencils at each table group so that you may add color. You have 5 minutes……

4. Characteristics all plants share…. Photosynthesis – they all make their own food Photosynthesis – they all make their own food Cuticle – a waxy layer that coats most of the surfaces of plants that are exposed to air and keeps the plant from drying out. Cuticle – a waxy layer that coats most of the surfaces of plants that are exposed to air and keeps the plant from drying out. Cell walls – all plant cells are surrounded by a cell wall Cell walls – all plant cells are surrounded by a cell wall Reproduction – sporophyte stage and gametophyte stage Reproduction – sporophyte stage and gametophyte stage

6. Sept. 12 th Bellwork You have 10 minutes from the bell ringing…… Define: 1.Nonvascular plant 2.Vascular plant 3.Gymnosperm 4.Angiosperm 5.Rhizoid 6.Rhizome

7. Cell Walls Cell wall – surrounds the cell membrane. The cell wall supports and protects the plant cell. Cell membrane – surrounds a plant cell and lies beneath the cell wall. Vacuole – stores water, helps support the cell, and plays a role in many other cell functions. Chloroplasts – contain chlorophyll that captures energy from the sun.

Photosynthesis Quiz 1.What gas does a plant use from the air around it to make its own food? 2.Where does a plant get the energy that it needs for photosynthesis? 3.What liquid is necessary for photosynthesis? 4.Where in the plant cell does photosynthesis occur? 5.What is the green pigment (located in the chloroplasts) that captures energy from the sun called?

11. Plant Classification

12. Seedless plants Nonvascular Do not have true stems, roots, or leaves Rhizoid is a rootlike structure that holds non vascular plants in place and help the plant to get water and nutrients Vascular Do have true stems, roots, and leaves Rhizome – underground stem from which new leaves and roots grow

20. Bell Work Sept. 22, 2014 Describe two advantages that seed plants have over seedless plants. Describe two advantages that seed plants have over seedless plants. How are flowering plants important to humans? How are flowering plants important to humans? Hint: answers are in sect. 3 of Ch. 6

21. Structures of seed plants Plants have roots and shoots. Vascular system between these two are connected. Xylem is vascular tissue that transports water and minerals through the plant from the roots to the shoots. Phloem is vascular tissue that transports food molecules to all parts of a plant. Both are found in ALL parts of vascular plants.

22. Roots Functions: Functions: supply plants with water and minerals supply plants with water and minerals hold plants in place hold plants in place store surplus food store surplus food

23. Stems- connects a plant’s roots to its leaves and flowers Support the plant body Support the plant body Transport materials between root system and the shoot system Transport materials between root system and the shoot system Some store materials Some store materials Herbaceous stems -are soft, thin, and flexible Woody stems-rigid and made of wood and bark

24. Leaves Main function is to make food for the plant

25. Flowers Sepal – one of the outermost rings of modified leaves that protect the flower bud Petal – one of the ring or rings of the usually brightly colored, leaf-shaped parts of a flower Stamen – the male reproductive structure of a flower that produces pollen and consists of an anther at the tip of a filament Pistil – the female reproductive part of a flower that produces seeds and consists of an ovary, style, and stigma Ovary – the lower part of a pistil that produces eggs in ovules
