One answer would definitely be winter snow and frost, since the frost kills the crops. And, possibly, summer when it is too dry for crops to get the right amount of water they need. :)

What main idea about the nature of the cell did historical scientists disagree on?
VLD [36.1K]

Explanation:

Scientists didnt belive that there are cells untill robert hooke (1665). He observed the cells in a cork slice with the help of a PRIMITIVE microscope

Leeuwenhoek (1674), with the help of an improved microscope, discovered free living cells in pound water for the first time.

It was robert brown in (1831) who discovered the nucleus in the cell.

Purkinjie in 1839 coined the term 'protoplasm' for the fluid substance of the cell.

THE CELL THEORY, that all plants and animals are composed of cells and that the cell is the basic unit of life, was presented by two biologists, schleiden (1838) and schwann(1839). The cell theory was fuether expanded by virchow (1855) by suggesting that all cells aris form PRE-EXISTING cells. With the discovery of the electron microscope in 1940,it was possible to observe and understand the complex structure of the cell and its various organelles.

Well, thats the history of the discovery of cells.
