Growth

Corn and Bean Plants Beginning and End Products

Meristem: tissue consisting of undifferentiated cells
                     -gives rise to various organs
                     -keeps it growing
Primary Growth: occurs at apical meristems and lengthens stems and roots

Secondary Growth: increases girth of root or stem & is a result of activity of vascular cambium

Vascular Cambium: lateral meristem that forms secondary tissue & is located between the xylem and phloem

Cork Cambium: secondary meristem that develops in region outside vascular tissues & produces periderm

Auxin:
   -development of embryo
   -leaf formation
   -phototropism
   -root initiation

Cytokinin:
   -promotes cell division in roots and shoots
   -bud growth
   -leaf senescence

Tropism: turning of all or part of an organism in a particular direction in response to an external stimulus (picture of the bean cotyledon)

Family Relationships

Dicot Characteristics:

the seeds have two cotyledons
the flowers usually have four or five floral parts
three pores of furrow in pollen grains
vascular bundles arranged like a ring in the stem
In monocot plants, the first shoot that emerges from the ground or from the seed is the epicotyl, from which the first shoots and leaves emerge.
The Tap root system is deep with a long primary root. Less important secondary roots branch off.
net array of leaf veins

Monocot Characteristics:

the seeds have only one cotyledon
the flowers usually have three floral parts
In the Fibrous root system of Monocots, the primary root is almost non-existent. The secondary roots are important in absorption, but are not as deep as the primary root of most dicots.
In dicots, the hypocotyl is what appears to be the base stem under the spent withered cotyledons, and the shoot just above that is the epicotyl.
vascular bundles distributed ground tissue of a stem
one pore or furrow in pollen grain
parallel array of leaf veins

Related Species:

Dicot-figs, daisies, tomato plants, and celery
Monocot- ginger, orchid, banana, and wheat

Side Note: Even though my two babies are very different in the way they grow into darling plants we are all one big happy family thanks to Jonah at the plant adoption agency. These babies are my world and I think they have grown up to be beautiful plants.

Life Cycle

Alterations of Generations: The regular alternation of forms or of mode of reproduction in the life cycle of an organism, such as the alternation between diploid and haploid phases, or between sexual and asexual reproductive cycles. It is a type of life cycle found in some algae, fungi, and all plants where an organism alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation. A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte).

Side Note: My babies didn't start out being my babies but over the course of about 8 weeks they have become my pride and joy. Its so hard to believe that they started out by going through meiosis, becoming spores, going through mitosis, then becoming gametes, getting fertilized and becoming a zygote and then they came to that agency and Jonah really helped me out with getting the best seeds.

Reproduction of a Flower

Stamen: the pollen-producing organ of the flower, which consists of the anther and filament

Anther-pollen-bearing portion of the stamen
Filament-the stem like structure that supports the anther

Carpel: a single pistil

Stigma-the part of the pistil that receives the pollen
Style-slender part of the pistil between the ovary and the stigma

Ovary-the enlarged lower part of the pistil in angiospermous plants, enclosing the ovules or young seeds.

Petal: one of the often colored segments of a flower
Ovule: a rudimentary seed
Sepal: one of the individual leaves or parts of the calyx of a flower
Receptacle: the modified or expanded portion of the stem or axis that bears the organs of a single flower or the florets of a flower head.

Steps of Reproduction:

pollen lands on stigma
pollen tube grows to ovary
egg is fertilized
the seed forms after fertilization
when the seed is ready, it disperses
the seed will then be carried somewhere by wind, or some other force of nature and land somewhere and germinate

This would have to be may favorite picture of my baby Pop, and I am not trying to single out Dean but Pop just looks so cute in this picture. Her stem is visible now and you can see by the color of the dirt that its not wet which means that the roots have been doing a good job soaking up the water and nutrients.

Food Delivery

Translocation: movement of materials from laves to other tissues

-ex: plants produce carbohydrates inleaves, but other nonphotosynthetic parts need them too, so they are translocated.

Phloem: tissue that carries nutrients. Made of long, continuous strands called vascular bundles that extend throught roots and stems
