Rainfall and soil conditions and amount of sunlight, also amou nt of shade for some cacti. Also elevation.

There are quite a few... Most of them European, Asian, and South American, and almost all of them are weeds.\n\nDandelions are introduced, but that's just one of hundreds.

Most likely through photosynthesis. Billions of plants can't be wrong.

The spider plant\n\nand the other link has a couple more

By crowding the root system it limits the size and health of the plant

Depends on the plant. Some plants grow faster than others.

Actually, I have no idea what the question is. But I was going to say a cactus which has needles, but the other guy is better with pine b/c pine needles is more normal, I think.

(1)seeds\n(2)like potatoes or garlic\n(3)like poplar trees or black currents being planted with no roots\n(4)like strawberries or mangrove through their limbs

The Daylilly only blooms for one day. but there is a cactus that has a flower that only blooms a few minutes before it welts and dies, sorry don´t know the name

APPEARANCE: Tress, shrubs and grass.\n\nHABITATS:   Terential, aquatic and sub terential.

They do not need a lot of water.  Replace the soil with cactus soil from any garden centre, and give it a nice sized pot. Mine are always doubling in size, I split one a couple of weeks ago and got nineteen plants from it, which I threw away because nobody wanted one, shame innit.

It is the place where the species was developed. That determines that each specie requires determined conditions to grow at optimal rates. I.e. eucaliptus requires a lot of water, so you will not find it in a dessert. \nIf you plant a tree outside its habitat it may not grow as much as in its habitat. It may inclusive die.

1)Roots\n are usually below ground and lack nodes, shoots, and leaves.  \nThey absorb NUTRIENTS and water from the soil\nanchor the plant in the soil, providing support for the stem\noften store food\nThe greatest number of plant roots are in the top foot of soil, with major feeder roots occurring in the top six inches. This knowledge is important for IRRIGATION, FERTILIZATION, and CULTIVATION. The amount and location of roots may be influenced by soil characteristics.\n\n2)Stems are generally upright and above ground, easy to locate and identify. However, many stems grow below ground or are ground-hugging. A modified stem is recognizable because it includes buds and sometimes leaves.  \nBuds and shoots generally develop on stems.\nThey carry nutrients and water from the roots to the other parts of the plant.\nIn some cases, stems also store food. \n\n3)Nodes are places on the stem where leaves are attached and buds form.\nRoots often form at nodes of creeping plants and when cuttings are taken for propagation.\nInternodes are the segments of the stem between nodes.\n \nThe quality and amount of available light and temperature affect the length of the internode. The distance between nodes can be long or short. This distance reflects growing conditions. Plants grown under poor light conditions may be spindly, with very long, thin, and weak internodes. \n\n\n4)Leaves are lateral outgrowths from the stem, most commonly flat, broad, and green. This maximizes their function of absorbing sunlight and transforming it into food. Leaves have evolved into many shapes and sizes, reflecting adaptations to the environment. Leaves generally consist of a stalk or PETIOLE and a blade or LAMINA. In simple leaves the lamina is in one piece. In compound leaves several pieces of lamina are joined to one petiole. \n\n\n5)Buds are undeveloped shoots and flowers. Buds are classified terminal or lateral. Another term for terminal is apical. Terminal buds can be identified by their location at the tip of a stem. Lateral buds are located at the sides of the stem.\n\nFlower buds are normally larger than VEGETATIVE buds. Cabbage and head lettuce are examples of very large terminal buds. Brussels sprouts are edible lateral buds. Broccoli is an example of edible flower buds.  \n\n\n6)The function of flowers is sexual reproduction through the production of seeds. A flower that has both male and female parts is called a perfect flower. Flowers that have only male or only female parts are called imperfect. A complete flower has four kinds of structure. Sometimes petals or stamens may be converted to nectaries so that it appears that there are other structures present. If a flower lacks one kind of structure it is said to be incomplete. The structures are arranged from the outermost inwards: The calyx is often green (but may be colored) and made up of two or more sepals  \n    The corolla is often colored (but may be green) and made up of petals  \n    The stamens are the male portion of the flower. Each consists of an anther, containing pollen supported by a stalk or filament  \n    Pistils (there may only be one) are the female part. Each includes one or more ovaries where seeds will form, a stigma that captures and holds pollen, and a style that supports the stigma on the ovary. \n\n\n7)A fruit is a ripened ovary or group of ovaries containing the seeds. It may include adjacent tissue that fuses with the ovary. Once the ovary is fertilized, the seeds develop and the ovary enlarges forming the mature fruit.  simple fruit forms from the ripening of the ovary of a single pistil. Examples include peanuts, sunflower seeds, grain (corn, barley, rice), acorns, walnuts, tomatoes, grapes, eggplants, citrus fruits, and apples.  \n    Aggregate fruit form from flowers with several simple pistils, such as raspberries and strawberries.  \n    Multiple fruit forms from a cluster of several flowers. A fruit is produced by each flower and these fruits merge into a multiple
