What is plants made of

The fruit is a covering for the seeds. It can be fleshy, like a mango, or hard, like a nut. The seeds contain new plants, and they need the right conditions to grow: water, warmth, and a good location, usually in soil. Seeds can be dispersed by wind, water, or animals.

Plants have developed several adaptations for seed dispersal. For example, some seeds have feathery hairs that help the seed to be carried long distances by the wind. Others are hidden inside the fruit of the plant. And some seeds float in water. Some plants reproduce themselves in a different way. They send out runners underground or tillers above the ground. Each new runner or tiller becomes a new plant. Both methods of reproduction allow plants to spread out and grow in new places.

Although the proteins coded for differ, the code is exactly the same. People and plants have a lot in common, though most people are more interesting conversationalists.

There are some exceptions. Andrew Breslin has been writing professionally since He studied molecular biology at Westchester University and frequently writes about science and mathematics.

PLANTS are permeated by the same gases that make up the atmosphere surrounding them: oxygen, carbon dioxide and nitrogen. Nitrogen in the form of a gas is neither used nor generated by any part of plants, unless we except the tubercles of certain roots, and so it occurs in about the same percentage inside the plant as outside of it.

On the other hand, both oxygen and carbon dioxide enter into combination with, and are liberated from, the plant tissues in varying amounts at different times.

The percentage of these two gases in the cavities of the plant vary through a considerable range. Photosynthesis also produces energy-rich carbohydrates like starch. Photosynthesis occurs in the chloroplast of a plant cell Have you ever wondered where plants get their mass? All those leaves and branches have to come from somewhere, but where? It turns out that the main ingredients for plant growth are water, air, and energy.

The molecule carbon dioxide is made of one carbon atom and two oxygen atoms. Air is made of tiny bits that we call molecules. If you had enough air molecules, you could even weigh them. Two of the molecules in air are oxygen and carbon dioxide. You may think oxygen is the most important molecule—we need it to live. But carbon is important too. All living things on Earth are made of carbon.

If you removed the water from our bodies, you would find that carbon makes up most of the rest of our weight, or mass. The same is true for plants. We get carbon from our food, but where do you think plants get carbon?

They don't get their carbon from the soil, or from the sun, or from water. Plants need energy from the sun, water from the soil, and carbon from the air to grow. Air is mostly made of nitrogen, oxygen, and carbon dioxide. So how do plants get the carbon they need to grow? They absorb carbon dioxide from the air. This carbon makes up most of the building materials that plants use to build new leaves, stems, and roots.
