Population Genetics and Evolution # #
Concepts
Evolution
-
one species to another, even more
-
-
-
-
Rates of Evolution
-
-
change in flowers, leaves, fruits, shoots, trichomes
-
-
Speciation
-
Phyletic Speciation
-
gene flow
-
pollen transfer
good travel distances
ragweed, grasses, conifers
-
-
-
-
Divergent Speciation
some evolve into new species, some remain same
-

Structure of Woody Plants #
Secondary Xylem: formation that occurs after the vascular cambium's secondary growth
Types of wood cells
Axial system
-
consists of fibers, hardness of wood depends upon the fibers it consist
-
-
Growth ring
a concentric layer of wood, shell, or bone developed during an annual or other regular period of growth
-
Heartwood and Sapwood
Heartwood: dead inner wood, usually dark
-
Sapwood: living, outermost portion of a woody stem, usually lighter in color
brings water and nutrients up from the roots through tubes inside of the trunk to the leaves and other parts of the tree
Reaction wood
-
wood that forms in place of normal wood as a response to gravity where the cambial cells are oriented other than vertically
Secondary Phloem: formed from vascular cambium
shape, size, number match with xylem ray
-
innermost layer, capable of conduction
-
Concepts
-
taller and wider
disadvantages
-
flight, insects, fungi, harsh environment
-
-
-
Conducting tissues
-
-
mineral, water-upwards, carbs- downward
-
-
-
Genetics
Monohybrid cross
-
-
-
-
-
-
Dihybrid cross
-
-
-
Crossing Over
-
-
farther apart genes are, the greater chance
Mutation
-
-
Causes of mutation
-
chemical, x-rays, ultravoilet light, and radiation from radioactive substances
Insertion mutation: caused by cutting of DNA by a enzyme and rejoining with a foreign DNA as repair process
Transposition mutagenesis: Biological process that allows genes to be transferred to a host organism's chromosome, interrupting or modifying the function of an extant gene on the chromosome and causing mutation.
-
DNA Replication
-
unwinding of DNA at the origin and synthesis of new strands accommodated by an enzyme known as helicase
The biological process of producing two identical replicas of DNA from one original DNA molecule #
-
Vascular Plants Without Seeds #
Early Vascular Plants
Rhyniophytes
-
upright stems, short cylinders with no leaves
-
-
-
Zosterophyllophytes
-
-
-
-
-
The term "Vascular Cryptogams"
-
have vascular tissue and lack seeds, flowers, fruits
-
Tissues and the Primary Growth Stems # #
-
-
-
-
-
-
between cells, the water moves from the cell having high water potential to the cell having low water potential in order to maintain the equilibrium
