The elements retain the appearance of bread and wine, but are indeed the actual Body and Blood of Christ. This is what is meant by Real Presence: the actual, physical presence of Jesus in the Eucharist. Christ instituted this Holy Sacrament of the Eucharist in order to remain with mankind until the end of time (Jn.
Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.During the process of photosynthesis, plants release oxygen into the air.People and animals need oxygen to breathe.hlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis. During the process of photosynthesis, plants release oxygen into the air.
In the process, the oxygen atom in the water separates from the hydrogen atoms and passes out as waste. The remaining hydrogen is collected and eventually synthesized into a carbohydrate molecule. The process that creates the actual food for the plant does not require light, so it's called a dark reaction. In another part of the leaf called the stroma, carbon dioxide that's been absorbed from the environment is reduced into carbon and oxygen.
