Transcript of Plant Kingdom- Division Anthophyta

Bio 103– General Botany
·Anthophyta are commonly referred to as the flowering plants.
·Anthophyta produced specialized structures, the flowers, in which enclosed seeds developed.
·Dominant members of the world’s flora.·Seeds are enclosed in an ovary.
·Matured ovary are called fruits.
·All have flowers but not all have colorful blossoms– such as corn tassels and catkins of oak trees.
Parts of a Complete Flower
The Division Anthophyta is divided into two
classifications
MONOCOT(Monocotyledoneae)
DICOT(Dicotyledoneae)
MONOCOT(Monocotyledoneae)
• One cotyledon• One leaf on
embryonic plant• Parallel venation
• Floral parts in 3’s or 6’s
• Fibrous roots
• Often grasses and the relatives of grasses are monocots.
• Two cotyledons• Two leaves on
embryonic plant• Netted leaf
venation
• Floral parts in 4’s or 5’s or multiples of 4 or 5
• Tap root
DICOT(Dicotyledoneae)
• Garden plants, trees and the like are dicots.
MONOCOTS VS. DICOT(Differences of Monocot and Dicot)
COTYLEDONThis is a significant part of the embryo within the seed of a plant.
Upon germination, the cotyledon may become the embryonic first leaves of a seedling. The number of cotyledons present is one characteristic used by
botanists to classify the flowering plants.
MONOCOTS VS. DICOT(Differences of Monocot and Dicot)
STEMThe stem of a monocot has the primary vascular bundles scattered while the
dicots have its primary vascular bundles in a ring.

LEAVESThe monocot has a parallel-veined leaves while the dicot have net-veined
leaves.

POLLENThe pollen of a monocot has only one opening while the dicot has three.

ROOTSThe root of a monocot is adventitious while the root of dicot is primary and

STRUCTURE
About fewer than 10% of monocot species and
about 50% of the dicot are woody.
ANTHOPHYTA
As an ovule develops into a seed, the ovary increases in size and forms the fruit. Flowers and fruits are of many different kind.
Seeds and fruits may be variously modified, a factor that frequently assists in seed dispersal. Wind, animals, humans, and water are the
most important agents of dispersal.
The enclosing of the seed within the fruit increases the possibility of survival in diverse environments.
The flowering plants, in addition to their aesthetic values, are our most important food and forage plants. Many fibers are obtained from the Anthophyta; so as cork and rubber. Drugs, beverages, and other
commercial products of various sorts are also obtained.
