 * __My hypothesis is If Vitamin D is applied to plants, The plants will grow more healthy due to the abundance of vitamin D. __**
 * __I will be using a Bean Plant as my organism and milk as my source of Vitamin D. The independent variable is the milk. The dependent Variable is the plant because the plant growth depends on the milk. __**

Plants can be both multicellular. Most plants are multicellular, and by most I mean that any which have leaves, stems, roots, flowers. There are a few unicellular plants, but these are small little things, for example the green layer you might find in pond water.

eukaryotes - mainly land plants and animals, large – macroscopic (Seen with the eye) – organisms, usually consisting of trillions of individual cells

Plants have tissues. The cells combine together to create tissues. Plants have three types of tissues. Dermal, Vascular, and Ground. Dermal tissues are found on the outer surface. Dermal tissue is composed of epidermal cells, closely packed cells that secrete a waxy cuticle that aids in the prevention of water loss. The ground tissue is found in the bulk of the primary plant body. Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue. Vascular tissue transports food, water, hormones and minerals within the plant. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells.

Plants do have organs. The roots, stem, and leaves. They have two reproductive systems that produce seeds which are spread by nature creating other plants alike. Plants are Asexual.

Plants have both types of metabolism. They use photosynthesis to create their own food and respiration is when plants give off oxygen from their leaves.
 * __Types of metabolism__**


 * __Reproduction__**

Asexual The plant produces seeds that are then spread by wind which go into the soil and make more plants.The flower is the reproductive organ of a flowering plant. pollen grains from the male stamen must be carried to the female part of the flower, the pistil. Pollination leads to the making of one or more seeds in a flower. The number of offspring depends to number of seeds spread.

The //gestation// period is a scientific term for the length of time, from conception to birth, an embryo turned fetus remains in the womb of its mother.

Algae and seaweed were the first plants exsisting 1.5 BYA. Then along came Liverworts, hornworts, and mosses in 420 MYA. lycopods came 410 MYA, Ferns 400 MYA, Then horsetails 375 MYA. Between the 420 MYA and 300 MYA, xylem, phloem, woody tissue, and seeds came into exsistance. 300 MYA, Gymnosperms such as conifers, ginkgos, and cycads sprouted. Betwwen 300 MYA and 120 MYA Flowers and carpel sprouted also. leading to angiosperms 120 MYA.

Bean plants are at the bottom of the foodchain. Everything eats Plants
