The pores or cells that Robert Hooke described in 1665 were actually plant cells he observed under a microscope. Hooke's work paved the way for our understanding of cells as the basic building blocks of life.
The structure being described is the cell wall. Plant cells have a cell wall composed of cellulose that provides structural support and protection, while animal cells do not have a cell wall. The cell wall surrounds the plant cell membrane, helping maintain the cell's shape and providing a barrier against external factors.
No, for example, onion plant cells don't. Even in green plants, chloroplasts are not in each cell, only in ones that receive sunlight. The presence of chloroplasts (green color) in the cells of a plant are an indicator of whether or not those cells are photosynthetic. Almost all terestrial plants are photosynthetic, but that does not mean that all of a single plant's cells are photosynthetic as described above. Photosynthetic cells are specialized to make sugar for the plant's energy needs from atmospheric carbon dioxide. The cells in other parts of the plant have other specialized functions.

The microorganism described is a bacteria. They are unicellular organisms that lack a membrane-bound nucleus but have a cell wall for structure and protection.
Plant cells, not animal cells.

The scientist who gave cells their name was Robert Hooke, a 17th-century English scientist. He observed plant cells under a microscope and described them as resembling tiny rooms or cells, hence coining the term "cells."

Plant cells do not have centrioles, but animal cells do.

All plant cells are eukaryotic cells
they are cells in a plant.
