To colonize, land plants had to overcome a number of difficulties. However, once this occurred they were able to exploit more abundant resources. Which of the following resources were more plentiful on land than in water during the early evolution of land plants?
A:) nitrogen
B:) water
C:) oxygen
D:) sunlight

D:) sunlight

Explanation:

Sunlight is one of the resources that are available in limited quantity in water bodies as compared to the land habitats since sunlight can penetrate up to a certain depth in water. However, land habitats have ample of sunlight available for plants. During early colonization of land habitats, dense forests were not present on land which in turn made even more sunlight available to the land plants of all height. Sunlight is one of the required factors to support plant growth and development.

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.
