The answer is the human body. Humans are made up of trillions of cells that all work together to make it possible for us to be alive and do everything from walking, talking and eating. Cells can be classified as eukaryotic or prokaryotic which means they have a nucleus or don’t have a nucleus respectively. All life on earth is made up of these two cell types which then form tissues, organs and organ systems which make up our bodies!
Cells are the smallest unit that performs an activity required for life. They come in many shapes and sizes but we only need one type-a somatic cell. Somatic cells maintain the structure of our bodies while other specialised cells perform tasks like digestion, breathing, vision etcetera. All cells are made of cytoplasm which is in turn filled with organelles-these would be the nucleus, mitochondria and ribosomes for example.
We need one type to make up our body’s structure: Somatic Cells! These somatic cells maintain the structures of our bodies while other specialized cells perform tasks like digestion, breathing, vision etcetera. The only cell that performs all the activities required for life on earth is a Somatic Cell-all others have their own specialised jobs! Cytoplasm fills these cells which include things such as a nucleus or mitochondrial but not both (in mammals). Different types of cytoplasms contain different organselle combinations which gives them specific functions within an organism.

Different types of cytoplasms and organelles give specialized function to organisms with somatic cells being capable of performing all necessary tasks by themselves. The only exception are human females who produce ova in addition to somatic cells, mitochondria are also absent from the ovum. This would explain why eggs cannot be used outside the reproductive tract although sperm can be.
The intestines which is a major site for absorption of nutrients will have villi lining its surface area and these contain microvilli (both tiny). These protrusions as well as various digestive enzymes help break down food particles into more manageable pieces that can then enter intestinal epithelial cells which line this inner layer of intestine wall tissue before entering bloodstream.
The liver which is responsible for filtering and secreting bile to the gall bladder as well as synthesizing proteins from amino acids for use in the blood, also has a large surface area with villi. These are called hepatic sinusoids. Kidney’s have nephron units that act like filters to maintain water balance in body fluids and help regulate electrolyte levels when necessary such as during exercise or illness.
Fetal cells will be present outside of maternal uterus only while unborn child is developing inside mother but then they disappear after delivery because there are no longer any nutrients available to them through placenta which was their sole source before birth since it provided hemoglobin needed by fetuses and other vital components not found within uterus.
Fetuses have the same organs as adults, but they are smaller and simpler in design which is why it takes so much longer to develop them than a baby’s more complex structure that develops through years of growth from the start of life until adulthood when body has matured completely. Fetal cells will be present outside of maternal uterus only while unborn child is developing inside mother but then they disappear after delivery because there are no longer any nutrients available to them through placenta which was their sole source before birth since it provided hemoglobin needed by fetuses and other vital components not found within uterus.
Structure that develops outside of uterus is called placenta which creates the umbilical cord that connects fetus to mother.
Ectoplacental cone is structure that performs all activities required for life but it can not do so independently, without maternal contribution.

Structure that develops outside of uterus, called ectoplacental cone, creates umbilical cord that connects fetus with mother. Umbilical cord allows for fetal cells to enter maternal bloodstream while unborn child inside womb but after birth it cannot do so because there are no longer any sources available for them within uterus as they were before delivery when only way for fetuses to survive was through blood vessels in placenta supplying hemoglobin needed by them. Placenta will not function without being connected to a uterine wall which provides it necessary support and protection from external environment.
