The term used to describe ancient cells with no nucleus is "prokaryotic cells." These cells, which include bacteria and archaea, are characterized by their simple structure, lacking membrane-bound organelles. Prokaryotic cells are considered some of the earliest forms of life on Earth.
Simple epithelial tissues have no blood vessels and line or cover structures.
Tissue cells are specialized cells that work together to perform specific functions within the body. They can be found in different types of tissues such as muscle, nerve, epithelial, and connective tissue. Tissue cells are typically organized into layers or structures that help support and maintain the overall structure and function of the tissue.
No, plant cells are not simple in design. They have complex structures and organelles that perform specific functions, such as chloroplasts for photosynthesis and mitochondria for respiration. These processes require intricate biochemical pathways and interactions within the cell.
Robert Hooke used the term "cells" in 1665 to describe the tiny, box-like structures he observed in cork slices. His observations were detailed in his book "Micrographia," where he compared these structures to the small rooms, or cells, inhabited by monks. This marked a significant moment in the history of biology, laying the groundwork for cell theory.
Prokaryotes are simple cell structures without a nucleus
Robert Hooke used the term "cells" to describe the small structures he observed in cork under a microscope in 1665. He likened these structures to the small rooms monks lived in, calling them cells. This observation marked the beginning of cell biology.
Simple epithelial tissues have no blood vessels and line or cover structures.

You would find cells with hair-like structures on the surface of the skin called cilia or on the lining of the respiratory tract. These structures play a role in moving substances along the surface of the cell or organ they are found in.
Robert Hooke was the first scientist to observe cork cells in 1662 using a simple microscope he had built. He coined the term "cell" to describe the box-like structures he saw, reminiscent of small rooms monks lived in, known as cells.
Ribosomes are the building structures in all cells.
