My project is on the affects of a flower growing in artificial light opposed to real sunlight. For
my hypothesis I think that it will grow better in artificial light because it’s getting cold out and
the sun is rarely out. Also because things tend to die around this time because of the cold air.
The independent variable in my project would be the sunlight and the dependent variable
would be the growth of the plant. My organism is a flower. The flower is the reproductive
structure of angiosperms or flowering plants. Compared to the reproductive structures of other
plants, It consists of four kinds of modified leaves, two of which (stamens and carpels, the latter
sometimes called pistils) bear pollen and seeds. Several non-flowering plants also produce
pollen and seeds on modified leaves, More than any other of the major plant groups, flowering
plants are ecologically related to animals. Modern animals, including humans, and flowering
plants are equally dependent upon each other. Most flowering species rely on animals for
reproduction. Insects carry pollen from the stamens to the carpels; bats and birds participate in
Pollination of some species. All flowers are angiosperms. This is an multicellular plant, it can be
an eukaryote or prokaryote.
Characteristics of the Dermal Tissue
• Outer protective covering
• Epidermis in non-woody plants
• Periderm replaces epidermis in woody plants
Characteristics of the Vascular Tissue
• Plumbing
• Transports materials (water & nutrients)between roots and shoots
• Xylem: conveys water from roots to shoots
• Phloem: conveys organic nutrients from where they are made to where they are needed
Characteristics of the Ground Tissue
• The rest (everything that isn’t Dermal or Vascular Tissues)
• Pith is internal to the vascular tissue
• Cortex is external to the vascular tissue
• Ground tissue is often specialized in storage, photosynthesis and support
There are 2 different organ types Vegetarian and Reproductive. The vegetarian organs are the
roots, stems, and leafs. The reproductive organs are variables. Photosynthesis and respiration
are both apart of the metabolism of a flower, The flowers respiration version of the human
action respiration is photosynthesis. There's only four parts to a flower: calyx, corolla, stamens,
and gynoecium. The corolla is the non-photosynthetic flowers (they do not have chloroplasts),
& stamens and gynoecium also do not have chloroplasts. The calyx, or sepals, is the only green
part of a flower, so it's the only part that can photosynthesize.
This is an asexual plant so the sperm from the pollen will travel down this tube to the ovules.
The ovules, or eggs, are stored in the ovary until they are fertilized. Plants can only fertilize eggs
of the same species. Special chemicals prevent sperm from fertilizing the eggs of flowers that
are not the same kind. The reproduction varies but it can have up to 1000 off springs. If it was
an sexual plant The anther produces male gametophytes, the sperm is produced in pollen grains,
which attach to the stigma on top of a carpel, in which the female gametophytes (inside ovules)
are located. After the pollen tube grows through the carpel's style, the sex cell nuclei from the
pollen grain migrate into the ovule to fertilize the egg cell and endosperm nuclei within the
female gametophyte in a process termed double fertilization. The resulting zygote develops into
an embryo. The first plant fossils found were woody magnolia-like plants dating back 93 million
years. Paleobotanists have more recently uncovered tiny herb-like flower fossils dating back 120
million years. Flowering plants, called angiosperms by scientists, were believed to be already
diverse and found in most locations by the middle of the Cretaceous period… 146 million years
ago.
