Identifying Plant Types and Uses Lesson 4 Identifying Plant Types and Uses

Next Generation/Common Core Standards Addressed! MS‐LS1‐6. Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms. [Clarification Statement: Emphasis is on tracing movement of matter and flow of energy.] [Assessment Boundary: Assessment does not include the biochemical mechanisms of photosynthesis.] MS‐LS2‐5. Evaluate competing design solutions for maintaining biodiversity and ecosystem services.* [Clarification Statement: Examples of ecosystem services could include water purification, nutrient recycling, and prevention of soil erosion. Examples of design solution constraints could include scientific, economic, and social considerations.] WHST.6‐8.2 Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information through the selection, organization, and analysis of relevant content. (MS-LS1-6)

Agriculture, Food and Natural Resource Standards Addressed! PS.02. Apply principles of classification, plant anatomy, and plant physiology to plant production and management. PS.02.01. Classify plants according to taxonomic systems. Sample Measurement: The following sample measurement strands are provided to guide the development of measurable activities (at different levels of proficiency) to assess students’ attainment of knowledge and skills related to the above performance indicator. The topics represented by each strand are not all-encompassing. PS.02.01.01.a. Identify and summarize systems used to classify plants based on specific characteristics.

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.

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

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.

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.

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

Common field crops and their uses Grain crops Sugar and oil crops Fiber crops

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.

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

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.

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. Soybeans, corn, and cotton are the most common oil crops. Other oil seeds include sunflowers and peanuts.

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

Cotton and Flax Cotton is the major crop grown for fiber. Flax is also grown for fiber. It is the subject of considerable research because of its potential in making paper.

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

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

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

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.

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

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. In New Mexico most commercial vegetable production takes in the lower Rio Grande valley in the Las Cruces, Hatch and Deming area.

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.

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.

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

Forest Products - Trunk The trunk is 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. The bark of the Pacific Yew is used in making the drug taxol, which holds promise in treating cancer.

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.

Review / Summary What are the three major areas of plant science? What are the uses of common field crops? What are the uses of horticultural crops? What are common products that are derived from trees?
