Answer:
Because of cell differentiation
Explanation:
Multicellular organisms are organisms that have many cells in their body system, unlike unicellular organisms that have just one. However, these many cells contained in a multicellular organism are of different types performing different functions.
Although they all have the same set of genes encoding the same proteins in them, they are able to become different and perform different functions via a process called CELL DIFFERENTIATION. Cell differentiation is the process whereby cells of a living organism becomes specific in their functions as they divide. This is a result of the REGULATED EXPRESSION OF GENES. The genes in each cell are not expressed at the same time, hence, they have different functions.
This is because if we strictly only allow people or things of our type to mingle, there are not enough of us to keep the population going, because then reproducing would be slower and we'd die out, and it would happen that some people who insist on finding "soulmates" that are perfect for them wouldn't find it in their group and refuse to reproduce, therefore making the population even lower.
Only 1 to 2% of the sunlight reaching the earth is used by the plants to make sugars.
The sunlight that reaches the plants are distributed in many ways. Some of the sunlight are reflected by the green leaf, some are absorbed by the structural and non chlorophyll cells and only a small fraction of the sunlight is actually used to carry out photosynthesis.
