How did Russian Botanist Konstantin Mereschkowsky discover the chloroplast?

Answer 1

Konstantin Mereschkowsky, a Russian botanist and biologist, discovered chloroplasts in 1905 as a result of his work with lichens. He wrote about the discovery of these organelles in the book "The Nature and Origins of Chromatophores in the Plant Kingdom".

Answer 2

Konstantin Mereschkowsky discovered chloroplasts in the late 19th century by studying plant cells under a microscope. He observed that chloroplasts resembled free-living cyanobacteria, leading him to propose the endosymbiotic theory, suggesting that chloroplasts were once independent organisms that were engulfed by plant cells and eventually evolved into an essential component of photosynthesis.

Answer 3

Chloroplasts contain chlorophylls, which traps light, so that photosynthesis can occur. They are mostly found in the palisade mesophyll cells because these cells get more sunlight.

Answer 4

Dmitry medvedev found them, in 1905
