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.
