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.

Answer: 30. D. Cell
31. A. Tissue
32. D. Biome
33. A. Population
34. D. Condensation
35. B. Precipitation
Explanation:
30. A cell is a largest component of life among the options given. As it includes within it molecule, and organelles required for the functioning and metabolism of cell.
31. A tissue is the smallest component of life. It is made up of group of cells. The cells combine together in tissue to perform a specialized function in organisms.
32. Biome is the largest ecological group which includes diversity of living organisms interacting with the physical environment. The biome is characterised by abiotic factors like climate, temperature, geography, and soil and also by the biotic factors such as flora and fauna.
33. Population is the smallest group which includes the members belonging to the same species living in the same location or region. These members are capable of inbreeding among themselves and producing viable offsprings.
34. Condensation is a process in which the water vapors being in high temperature cools down in the sky to form clouds. It is the part of water cycle.
35. Precipitation is the part of the water cycle. In this the clouds formed after the condensation process, due to increase in amount of water vapors in them the water falls off under the effect of gravity. The precipitation is in the form of sleet, snow, hail, drizzle and rain.
