Cells were first identified by Robert Hooke in 1665 when he observed the box-like structures in cork tissue under a microscope. In the 1670s, Antoine van Leeuwenhoek became the first to observe living cells. Both their work was instrumental to the understanding of cells and cell theory.
In 1665, experimental scientist Robert Hooke was the first to identify cells. He used the term 'cell' to describe the box-like structures he observed in a cork tissue using a lens, as documented in his publication Micrographic. Hooke's concept of a cell was based on his microscopic observation of the dead cork tissue. He likened the tiny subdivisions in the cork to the small rooms, or cells, that monks resided in.
Antoine van Leeuwenhoek, in the 1670s, became the first person to observe living cells, specifically bacteria and protozoa. Advances in lenses, microscope construction, and staining techniques throughout the years enabled the viewing of components within cells, further refining our understanding of cell structure and function.

Answer: The correct answer is Plantae kingdom.
A cell with chloroplast and a cell wall made of cellulose would likely belong to plantae kingdom. This is because cell wall of plants is primarily made up of cellulose, which is a carbohydrate that provides rigidity to the cell wall.
Chloroplast is a specialized membrane bound organelle present in green plants and algae. It is the site of synthesizing food through photosynthesis.
Thus, Plantae kingdom is the right answer.

The lactate dehydrogenase enzyme carries the lactic acid fermentation.
Lactic acid fermentation may be defined as a process through which muscle cells and bacterial species like Lactobacillus oxidize NADH by transforming pyruvate into lactate.
The enzyme lactate dehydrogenase carries the conversion of pyruvate into lactate. It involves the oxidation of NADH.
During this anaerobic process, ATP is produced in an average amount which provides the energy to muscle cells in oxygen-deficient conditions.
Therefore, it is well described above.

Answer:
Lactate dehydrogenase (LDH or LD) is an enzyme found in nearly all living cells. LDH catalyzes the conversion of lactate to pyruvate and back, as it converts NAD+ to NADH and back. This is how it allows glycolysis to continue.
