In the process of respiration of organisms, carbon dioxide is formed, compare how it is released from the organism

In the process of respiration of organisms, carbon dioxide is formed, compare how it is released from the organism of plants and animals, consider this with the examples of both unicellular and multicellular organisms of the indicated kingdoms.

Animals emit carbon dioxide when they breathe. It leaves the body because CO2 binds to hemoglobin in red blood cells and leaves red blood cells in the lungs when carbon dioxide is replaced by oxygen. Plants absorb carbon dioxide for photosynthesis. Oxygen is released during this biochemical reaction. It leaves the cells through the pores. Unicellular organisms breathe over the entire surface of the body. All life processes take place in one cell of the simplest animals and plants. The simplest plants also absorb carbon dioxide.
