The order in which the earliest organisms evolved -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
On the earth, various kinds of organisms evolve at different geological times, and on their evolution, they consider the oldest or youngest organisms:
- Archaebacteria and bacteria was the oldest living organism on earth was, they lacked a membrane-bound nucleus and cell.
- The protists evolved after the bacteria, they were multicellular prokaryotic organisms.
- Fungi and the shell-less invertebrate, much-developed organisms in terms of body organization and structure. These have membrane-bound, well-defined cell membranes, and a nucleus. They even had a tissue level of organization.
- Green algae evolve after protists which belong to the division Thallophyta of the plant kingdom. These are photosynthetic as they have chlorophyll in the cell.
- Shelled Invertebrates are the youngest organisms that evolved recently among these.
Thus, the correct order is -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
