What is a plant?
They areTHE BASIS OF ALL DIETS.
They ARE THE ORIGINAL SOLAR COLLECTORS
THEY STORE FOOD FOR THEMSELVES IN ROOTS, STEMS, etc.
THEY STORE FOOD FOR OFFSPRING IN SEEDS
THEY STORE FOOD TO ATTRACT ANIMALS IN THEIR FRUIT
What is Pollen?
the fine spores that contain male gametes and that are borne by an anther in a flowering plant.
What is the Stamen?
The male reproductive organ of the flower.
What is the Stigma?
the apical end of the style where deposited pollen enters the pistil .
What is Cultivar?
Cultivar is an abbreviation of 'cultivated variety'. Each cultivar is a version of a plant species that is not genetically different enough to be a separate species. For example, characteristics may include a different flower or leaf color, fruit flavor, or height.

They are produced in nurseries by taking cuttings instead of seeds - with seeds, it would not stay true to the desired characteristics.
What is a Monocot?
One of two main divisions of flowering plants, characterized by having a single cotyledon (seed leaf); examples include grasses, orchids, bamboos, and palms.
What is an Evergreen?
a plant having foliage that persists and remains green throughout the year.
What is a Terminal Bud?
a bud that grows at the end of a stem or branch. Often contrasted with axillary bud .
What is a mesophyte?
land plant growing in surroundings having an average supply of water; compare xerophyte and hydrophyte
What is a soil horizon?
layer of soil developed in response to localized chemical and physical processes resulting from the activities of soil organisms, addition of organic matter, precipitation, and water percolation through the layer.
What is Alkaline PH?
relating to or containing an alkali; having a pH greater than 7; "alkaline soils derived from chalk or limestone"
What are lateritic soils?
is a surface formation in hot and wet tropical areas which is rich in iron and aluminium and develops by intensive and long lasting weathering of the underlying parent rock
What is Friable?
crumbly: easily broken into small fragments or reduced to powder.
What is a lawn?
a field of cultivated and mowed grass.
What is a pistil?
the female ovule-bearing part of a flower composed of ovary and style and stigma
What is a peduncle?
The stalk which supports a head
What is a tree?
a tall perennial woody plant having a main trunk and branches forming a distinct elevated crown; includes both gymnosperms and angiosperms
What is dicot?
One of two main division of flowering plants, characterized by having two cotyledons (seed leaves); examples include most fruiting and flowering trees, and most annual and perennial flowering plants.
What is deciduous?
plants or trees lose their leaves for part of the year (ie winter). Examples of these trees include maple, birch, oak and aspen.
What is a lateral bud?
a bud that grows from the axil of a leaf and may develop into a branch or flower cluster. Also called axillary bud.
What are xerophytes?
desert plant: plant adapted for life with a limited supply of water; compare hydrophyte and mesophyte
What is acidic pH?
being or containing an acid; of a solution having an excess of hydrogen atoms (having a pH of less than 7)
What is monoculture?
a term used agriculturally to describe the planting of a single species of a crop.
What is a sporophyte?
The plant (or the diploid phase in its life cycle) which produces spores by meiosis in order to produce gametophytes
What is a sepal?
often resemble reduced leaves and function in the protection of the bud; may be modified to function more like a petal
What is an anther?
the upper part of the stamen, male flower part, in a capsule-like structure that splits to release yellow pollen.
what is an ovary?
it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals.
What is a shrub?
A woody plant smaller than a tree, and usually with several stems from the same base
What is an annual?
a plant that completes its entire life cycle within the space of a year
What is a broadleaf?
having relatively broad rather than needlelike or scalelike leaves
What is a budscar?
the marks remaining after bud scales drop in spring.
What is a halophyte?
plant growing naturally in very salty soil
What is a pinnate?
divided, as with a compound leaf, so the segments are arranged on two sides of a middle axis; featherlike in appearance
What is topsoil?
Surface layer of soil with higher organic content, A horizon.
What is glacial till?
geological deposit consisting of mixture of clay, sands and rocks of varying size and type picked up and dragged along by a glacier then dumped as the ice melted
What is the Munsell Soil Color guide?
Developed by this person and the U.S.D.A. Soil Conservation Service, this Color System is the field and laboratory standard for classifying soil color, rocks, and archaeological specimens.
What is Bluegrass?
valuable meadow and pasture grass in Europe and especially central United States having tall stalks and slender bright green leaves; a chief constituent in lawn grass mixtures
What is a gametophyte?
The pollen grain is the male form of this and the embryo sac is the female form of this.
What is the calyx?
the whorl of sepals of a flower collectively forming the outer floral envelope or layer of the perianth enclosing and supporting the developing bud.
what is a filament?
the stalk of a stamen
What is vascular?
of or pertaining to the conductive tissues of a plant stem. These tiny tubes move water up from the roots, and sugars and other materials down from the leaves.
What is biennial?
plant having a life cycle that normally takes two seasons from germination to death to complete; these flowering plants usually bloom and fruit in the second season
occurring every second year
What is a lenticel?
one of many raised pores on the stems of woody plants that allow the interchange of gas between the atmosphere and the interior tissue
what is a palmate?
a leaf resembling an open hand; having lobes radiating from a common point
what is soil?
The top layer of the Earth's surface, containing unconsolidated rock and mineral particles mixed with organic material.
What is subsoil?
the layer of soil between the topsoil and bedrock
What is bedrock?
solid unweathered rock lying beneath surface deposits of soil .
What is a ribbon test?
•1
Moisten a ball of soil.

•2
Hold the soil sample in your hand, palm up.
