Robert Hooke is the first person to observe cells as microscopic structures.
He was of British descent and, fun fact, he discovered cells by looking at a sliver of cork under a microscope lens (although the 'fun fact' is heavily simplified).
Answer:
constants.
Explanation:
Climate-controlled room are almost indoor and are kept with stable temperatures and also with stable humidity levels.
<u>In biological experiments, it used to establish constant parameters like temperature, humidity, exposure to different things, growth of organisms and etc.</u>
These rooms provide better shelf life and thus better results.
Answer is the phylum is Pteridophyta. Pteridophytes are first land plants, examples ferns, <em>Lycopodium, Selaginella. </em>Members have liginified cells and developed conducting tissues called vascular system to conduct water and synthesized food. They reproduce through spores, seeds do not develop in pteridophytes.

Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. They are domains of the old kingdom Monera.
<h3>What are Archaebacteria and Eubacteria? </h3>
Archaebacteria and eubacteria represent two different domains of the old kingdom Monera.
Monera is formed by unicellular prokaryotic microorganisms that do not have membrane-bound organelles and cell nuclei.
Both Archaebacteria and Eubacteria exhibit sequence variation in their ribosomal RNA, which can be used to classify them.
