Botany Fin

Botany Final

Pollination Polen cell is transfered to the female plant part and the eggs are fertilized
Guard Cells Cels on the underside of the leaf that open and close the stomata, or leaf pores
Complete Flower Flower that has both male and female parts; sexually complete
Epidermis Skin of the leaf
Pistil Female reproductive part of a flower, contains the female sex cells in the ovary
Midrib Large center vein from which all other leaf veins extend
Phloem Tubes in plant stems that conduct food from leaves through the stem to the roots
Oxidation Combining something with oxygen
Chlorophyll Green substance that gives many plants their green color and is necessary for photosynthesis
Petals Type of leaf on flower, usually considered the most striking part of the flower, act to attract insects for pollination
Veins Structural frame of leaf
Style Tube in the pistil that leads from the stigma to the ovary and through which pollen reaches the egg
Stigma Part of the pistil that catches pollen on its sticky surface
Anther Sack-like structure at the top of the stamen that contains pollen (the male sex cell)
Stamens Male reproduction part of the flower containing the male sex cells or pollen
Dicots A plant having two cotyledons or seed leaves
Tap roots Longer center root with fewer root hairs
Margins Edges of plant leaves
Roots Anchor plant, absorb water and minerals, store large quantities of plant food,propagate or reproduce some plants
Nodes Joint of a stem; the swollen place where leaves and buds are generally attached
Internodes ?????????????? Spaces between two nodes
Vascular bundles A strand of conducting vessels in the stem or leaves of a plant, typically with phloem on the outside and xylem on the inside.
Cotyledon The first leaves to appear on a plant: seed leaves
Transpiration Loss of water through the leaves or stems of plants
Respiration Breathing process in which plants and animals consume oxygen and release carbon dioxide
Terminal bud A bud at the end of a stem marking the end of the years growth
Photosynthesis Manufacturing of food by green plants in which carbon dioxide and water are combined in the presence of light and chlorophyll to form sugar and oxygen
Incomplete flower Does not have both male and female parts
Xylem Tissue that transports water and nutrients from the roots to the stem and leaves
5 parts of the external leaf structure Blade, petiole, veins, node, axillary bud
3 forms that food is stored in Sugar, starch, protein
Two main functions of the stem support leaves / branches, contains passages for food and water movement
2 most important things humans receive from plants Food and oxygen
3 main things that xylem, or wood, does for the stem of a plant Supports leaf and reproductive structures, used for food storage,and the movement of materials such as water and minerals to leaves and manufactured food from leaves to roots
Chloroplasts function Make the food
What three things do green plants need to manufacture food? Carbon Dioxide, water, and sunlight
What does a fertilized egg from an ovary grow into? ?????? Seedling - embryo
Seedling Young plants that have been germinated several days
Egg Ovules - if fertilized, become seeds
Tissue culture Micropropagation- method for rapidly reproducing plants using terminal bud tissue
Flat Wooden box with slotted bottom used to start seedlings
Endosperm Food suply for the young, developing seedling that is contained in the seed
Seed coat Outer covering of the seed
Enhanced Quality has been improved
Hybrid Offspring of two different varieties of one plant that possesses certain characteristics of each parent
Pollen Male sex cell in plants
Cotyledons First leaves that appear on a plant
Hardening off Gradually subjecting plants to more difficult growing conditions in preparation for transplanting
Propagation To increase in number, to reproduce
Embryo A new plant that is developed as a result of fertilization
Come true to seed Reproduce exact duplicates of the parent plant from seeds
Vermiculite A light mineral with a neutral pH used to increase the moisture-holding capacity of media
Jiffy Mix A 50/50 peat/vermiculite mix
Sphagnum Dehydrated remains of acid bog plants, used in shredded form for starting seeds
Peat moss Partially decomposed vegetation that has been preserved underwater
Perlite Gray-white material of volcanic orgin used to improve aeration of the media
Sand A loose granular substance, typically pale yellowish brown, resulting from the erosion of siliceous and other rocks
Soil The upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles
List and define the three basic parts of a seed Seed coat-protects seed, endosperm-food storage tissue that nourishes the embryo during germination, embryo-new plant develops as a result of fertilization
The best Temperature for germinating seeds is... 65 to 70
The hardening off process is done to do what three things Prepares plants for the transition to the outside environment by withholding water, decreasing the air temperature, and increasing the amount of sunlight.
Layer The stem or root that is rooted during the layering process
What modern development has greately increased the success rate of air layering Polyethylene film
Girdle To remove all the cambium and bark from a stem for a short distance to aid in rooting
Two main functions of landscape industry Improve out natural environment and meet the needs and desires of people
List the three major professions of the landscape industry Landscape architect, landscape contractor, landscape maintenance contactor
List two subjects integrated to make landscaping Art and Science
List the five basic principles of landscape design 1.Simplicity 2.Balance 3.Focalization of interest 4.Rhythm and line 5.Scale and proportion
Cubic Yard formula Length X width X depth / by cubic feet = cubic yards
Xeriscaping Landscaping technique used to practice water conservation
Acer Maple - generic name
Family Related plants with similiar flower structures
Pelargonium A genus of flowering plants which includes about 200 species of perennials, succulents, and shrubs, commonly known as geraniums
Genera A group of species exhibiting similar characteristics
Betula Birch

For plants, what is the most important type of useful water in the soil? Available capillary water or field capacity
What is the PH scale? A scale of 1 to 14 that indicates the level of acidic or alkaline content of soil
What do the numbers stand for? A solution with a ph of 7.0 is neutral. Solutions with a lower ph value are increasingly acidic, and those with a higher ph value are increasingly alkaline
List soil particles by increased size Organic matter,clay,silt,sand
Where is it often easiest to see nutritional deficiencies in plants? On the leaves of the plants
4 main parts of complete flower Sepals, petals, stamens, pistil
Six types of layering Air, compound, simple, stool, trench
Three objectives of residential landscaping To accent landscapes, add color to landscape, direct traffic patterns in a garden
