Lesson 4

1. Lesson 4 Identifying Plant Types and Uses

2. Next Generation Science/Common Core Standards Addressed! • RST.11‐ 12.1 Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account. (HSLS1‐1) • WHST.9‐12.7 Conduct short as well as more sustained research projects to answer a question (including a self generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation. (HS‐LS1‐3) • SL.11‐12.5 Make strategic use of digital media (e.g., textual, graphical, audio, visual, and interactive elements) in presentations to enhance understanding of findings, reasoning, and evidence and to add interest. (HS‐LS1‐2)

3. Agriculture, Food and Natural Resource Standards Addressed • PS.02.01. Classify plants according to taxonomic systems. • PS.02.01.01.a. Identify and summarize systems used to classify plants based on specific characteristics.

4. Bell Work! • Describe plant science and its three major areas. • Identify common field crops and their uses. • Define horticultural crops and describe their uses. • Describe forestry and forest products.

7. Interest Approach • Looking at the variety of plants in front of the you, which include samples of field crops, horticultural crops, and forest crops, ask yourself why these crops are grown. • What purposes are they used for by humans and other animals?

8. Plant Science and its three major areas • Plant Science – the study of structure, functions, growth, and protection of plants. • 3 areas of plant science: • Field Crops • Horticultural Crops • Forest Crops

9. Field Crops • Plants grown in large fields used for oil, fiber, grain, and similar products. • They are often grown for their seed, such as corn and wheat. • Agronomy: The specialized area of plant science that deals with field crops.

10. Horticultural Crops • Plants grown for food, comfort, and beauty. • In some cases, horticulture overlaps with field crops. • However, in most cases, horticultural crops are not grown on vast areas of land.

11. Forest crops – production of trees • Forestry includes growing trees and the production of wood, food, and medicinal products. • Many forest crops are grown on tree farms or cultured forests. • Careful thought and planning goes into the production of forest crops on tree farms.

13. Common field crops and their uses • Grain crops • Sugar and oil crops • Fiber crops

14. Grain Crops • Plants grown for their edible seeds, does not include horticultural crops. • Cereal grain is the seed of grass type plants grown for food and animal feed. • Grain and cereal crops include rice, corn, wheat, oats, barley, rye, and sorghum.

16. Sugar and Oil Crops • Are produced for two important commodities: • sweeteners • vegetable oil.

17. Sugar Crops – source of sucrose • Sucrose:commonly used as table sugar or as a sweetener in foods and beverages. • It is a carbohydrate that provides energy for the human body. • The major sugar crops are sugar cane and sugar beets.

19. Oil Crops • Plants grown for the vegetable oil contained in their seeds and fruit. • The seeds of about 40 crops are used to make oil. • Soybean, corn, linseed and cotton are the most common oil crops. • Other oil seeds include sunflowers, peanuts, safflower and canola.

20. Fiber Crops • Are grown for the fiber produced in their fruit, leaves, or stems. • Fibers are tiny, threadlike structures used in making cloth and paper. • Crops grown for fiber include cotton and flax.

22. Horticultural crops and their uses • Two major areas of Horticulture: • Ornamental • Food crop production

23. Ornamental Horticulture • Growing and using plants for their beauty. • It includes: • floriculture • landscape horticulture.

24. Floriculture • The production and use of plants for their flowers and foliage. • Roses and chrysanthemums are examples of floriculture crops.

25. Landscape Horticulture • Growing and using plants to make the outdoor environment more appealing. • It includes shrubs, lawns, and flowering plants. • Interiorscaping: using plants indoors to create an attractive environment. • Offices and malls often use plants to increase the appeal of their surroundings.

26. Food crop horticulture • Growing plants for food. • Is divided into two areas: • Olericulture • Pomology

27. Olericulture • The science of producing vegetable crops like tomatoes, peppers, asparagus, and broccoli. • It is carried out on a large scale in warmer areas of the country like South Florida, Texas, and California. • Primary NM crops include chili, lettuce, cabbage and onions. Primarily in the lower Rio Grande valley.

28. Pomology • The science of producing fruits and nuts. • It includes growing, harvesting, and marketing the crop. • Common pomology crops include oranges, lemons, apples, cherries, pecans, and walnuts. • NM ranks number 2 in the nation in pecan production!

29. Forestry • The art and science of managing forests to yield maximum forest products and services. • It is the managing of forest lands to meet human needs.

30. Forest Products - Crown • The crownof the tree is the upper portion of the tree. • The crown produces such items as fruits and nuts, decorations, and oils.

31. Forest Products - Trunk • The trunkis the main stem of the tree. It is used in producing lumber and other wood products. • The tree’s bark is also used in producing oils, dyes, and drugs. • For example the bark of the Pacific Yew is used in making the drug taxol, which holds promise in treating cancer.

32. Forest Products – Stumps/Roots • Tree stumps are used in making veneer wood products. • They are also used in producing turpentine, pine oil, and resin. • Tree roots are used in the production of tea, oil, and turpentine.
