In order to grow, plants need carbon dioxide, water, sunlight, and nutrients. The plants get carbon dioxide from the air (that’s what we breathe out!), water from the soil or rain, sunlight from the sun, and nutrients from the ground. In a process called photosynthesis, the plants combines these ingredients to make food for itself. As a result of this, plants release oxygen into the air that we (and animals) need to breath to stay alive! The plants help us by giving us air, and we help the plants by giving them water and soil and sunlight.

I think what you're asking is how do plants grow/make fruit? This is a great question! Basically, plants, usually in the cells in their leaves, capture sunlight and turn CO₂ (carbon dioxide) and H₂O (water) into sugar (C₆H₁₂O₆).

This sugar can be used by the plants to make energy, when can be used to get bigger. Just like when you eat food, you turn that food into energy to grow.

Plants live partly in the air and sunlight, and partly in soil or dirt [did you ever think about how 'soiled' and 'dirty' mean the same thing? I didn't.]

Plants got carbon dioxide from the air and energy from the sunlight. From the soil, they get minerals [iron, manganese and so forth] and other elements [phosphorous and potassium]. They actually get nitrogen from microbes that live on the roots of some plants like bean plants. The microbes do a chemical reaction that turns nitrogen gas into ammonia, NH₃, which plants can use.

Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Plants also need small quantities of iron, manganese, zinc, copper, boron and molybdenum, known as trace elements because only traces are needed by the plant.

Plants get:
-Hydrogen and oxygen from water, that they take up through their roots;
-Carbon from carbon dioxide, in the air
-Nitrogen, magnesium, phosphorous, and sulfur out of the soil, dissolved in the water that they take up;
-Energy from sunlight
