BIOS 305- Biology of Land Plants-Fall 2018 Assignment 2 (20 of 115 ponts remuining) -Start seeing trees- Due Wed., 19 Sep There are mamy types of troes on the NIU campus. In this assignment, you are asked to become mone familiar with maples at NIU. There are at least seven different maples on campus (comon names: bovekder, Japanese, Norway, paperbark, red, silver, and sugar mapks) phs one unique maple tree called Temple's uprigh." Using avaiable resources respond to the folkwing 1) Systematies: Lst the taxonomic gemus and family (use correct typozgaphies) m which maples are chsified and indicate the source of your nformsation int the family name beins with 2a) Morphology: Of the eight types of maples on campus, boxelder has a unique type of leaf Explain how the leaf of boxelder differs from those of the seven other types of maples on campus. Indicate the source of your information 2b) Name and describe the type of fruit that a mapke tree produces. Mature trees of three types of maples on campus produce fruits at this time of year. Collect a pair of maple fhuts fom one of these and attach i to the back of this sheet (do not climb trees!). (You receive two pts. of extra credit for listing the correct scientific name of the mupke tree that produced your attached fruit) 3a) Horticulture: Temple's upright" is a cultiar of the sugar maple that has a unique "columnar" appearance (see images at http//wp.hort.net/plant/acesutu01). Find the one Templke's upright mapk on campus (in the map area below) and precisely georeference it with as latitude and longtude coordinates from a GPS app. Use decimal format. Optional: you may aso choose to give a description of nearby campus buildings/landmarks Lucinda Ave 62 3b) In addition to their use as landscape trees describe another use besides furniture or lumber that certain types of maples have in industry 10 48Explanation / Answer
1. The Sapindaceae is a family of flowering plants in the order Sapindales known as the soapberry family in which maples are classified. Acer is a genus of trees or shrubs commonly known as maple. Source of information is Maples for Gardens: A Color Encyclopedia written by C. J. van Gelderen & D. M. van Gelderen.
2. a. Unlike most other maples (which usually have simple, palmately lobed leaves), Acer negundo (box-elder) has pinnately compound leaves that usually have three to seven leaflets or rarely nine leaflets. Only A. negundo regularly displays more than three leaflets. Source of information is Maples for Gardens: A Color Encyclopedia written by C. J. van Gelderen & D. M. van Gelderen.
2. b. The one-winged propeller type fruit is found in maple, called a samara. A pair of fused samaras about 1 inch long. A samara is a simple dry fruit and indehiscent. A samara is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. The shape of a samara enables the wind to carry the seed farther away and is thus a form of anemochory (the dispersal of plant seeds or spores by the wind).
3b. The sugar maple (A. saccharum) is tapped for sap (Sap is a fluid transported in xylem cells or phloem sieve tube elements of a plant. These cells transport water and nutrients throughout the plant.), which is then boiled to produce maple syrup or made into maple sugar or maple taffy (sugar candy). Maple sugar is a traditional sweetener in Canada and the northeastern United States, prepared from the sap of the maple tree. It takes about 40 litres (42 US qt) of sugar maple sap to make 1 litre (1.1 US qt) of syrup but many do not have sufficient quantities of sugar to be commercially useful.
