Which cell structure is thought to have arisen through an endosymbiosis in plant but not animal cells?
tamaranim1 [39]

Answer:

Chloroplast

Explanation:

Endosymbiosis theory explains the origin of chloroplast and mitochondria in the eukaryotic organisms.

When the pro-eukaryotes engulfed the blue-green algae or photosynthetic bacteria, these bacteria formed the symbiotic relationship with the pro-eukaryotes. These photosynthetic bacteria transformed into the chloroplast organelles of the eukaryotes which can capture the sunlight and use it in the synthesis of glucose molecules. These eukaryotic cells later formed the plant kingdom.

Thus, the chloroplast is the correct answer.

Which shows the correct order of steps in the formation of coal? Layers of dead plants pile up → plant matter is buried by rocks
Doss [256]
The appropriate answer is d. Dead plants in a swampy environment is the perfect environment for the beginning of the coal forming process. Over time layers pile up in this anaerobic environment. The plant or organic material gets buried overtime by dirt or rocks. Millions of years of burial will expose the matter to heat and pressure and will eventually lead to the formation of coal and other petroleum products.
