Answer 1

thats a pretty huge question.

here is the general jist.

a seed or plant contains dna that it received from the previous generation. the dna codes for genes that are expressed and carry out a variety of functions. these include things like gathering materials from the environment, to using them for structure or energy, to providing for defense. as the plant grows, it continues to gather energy and materials from its environment, with the dna being the "hard drive" containing instructions on what to do.

Answer 2

In order for a plant to grow and change it needs a building permit from Mother Nature.

Answer 3

They get their nutrients through their roots from the soil, the sunlight also helps with photosynthesis. And of course, don't forget the water. =)
Is there any plant in particular that you're thinking of? Different plants have different requirements.

epidermis-outer layer of cells on a leaf

stoma-opening in a leaf epidermis where water vapor escapes and carbon dioxide and oxygen can pass (stomata-plural)

transpiration-loss of water vapor through stoma

chlorophyll-green pigment (coloring) in plants Photosynthesis -process in which energy from the sun is used to produce FOOD
-produces sugar (food) and oxygen
-occurs in plant cells with chlorophyll
-takes place in evergreens year round Respiration -occurs in cells of ALL organisms
-process that combines sugar and oxygen to release ENERGY
-energy is used by cells to do work (growth & repair)
-cells release carbon dioxide and water

deciduous trees-trees that have no leaves during the winter
