Tissues
The structure of a bacteria cell that performs a similar function to the skin of a human is the cell wall.
Shared evolutionary origin: Organs must have a common ancestral structure that has been modified over time. Similar structural organization: Homologous organs should have similar basic structure and pattern of development. Similar function: Although homologous organs may have different functions in different species, they should share a common underlying function or purpose.
the alveoli
Cells with similar function and/or structure make up tissues in the body.
Cells do not all carry out the same function even though they share similar structures.

Structure 4
The structure of a bacteria cell that performs a similar function to the skin of a human is the cell wall.
Both are made from a structural protein called Keratin.
Shared evolutionary origin: Organs must have a common ancestral structure that has been modified over time. Similar structural organization: Homologous organs should have similar basic structure and pattern of development. Similar function: Although homologous organs may have different functions in different species, they should share a common underlying function or purpose.

Structure and function
The cell membrane acts as a protective barrier for the cell, similar to how bark provides protection for a tree. Both structures help regulate what enters and exits the cell or tree, and also provide structural support.
