The cell wall (and cellulose that makes up most of the cell wall).
The new plant if cross pollinated need to have its pollinators at that place for its success to grow and multiply.
Well for the basics THE SUN OR LIGHT AND WATER. You will need dirt also. Those are the basics. If you want to check for more detail check one of the other websites. These are just the basics. (Fun fact: Did you know most plants will grow to the side where the light is so if you want the plant to grow straight good luck)

To make plant grow faster
photosynthesis...your plant needs light to grow. or if u want to to grow good use miracle grow..
cell walls are in plant cells, because the cell wall is rigid (up to many micrometers in thickness) and gives plant cells a very defined shape. While most cells have a outer membrane, none is comparable in strength to the plant cell wall. The cell wall is the reason for the difference between plant and animal cell functions. Because the plant has evolved this rigid structure, they have lost the opportunity to develop nervous systems, immune systems, and most importantly, mobility. An animal cell floats freely in the body, so it doesn't need a cell wall, and can't live with a cell wall.
yes all plant need light to grow
Sun and water. Most of plants need solid too. Add fertilizer to help it to grow better, but it is not really a need.
