The two challenges facing plants as a consequence of their lack of mobility.
Introduction:
Plants are mainly multicellular predominantly photosynthetic eukaryotes of the kingdom Plantae. Plants do not show locomotion; instead they show tropic movements in response to sunlight, gravity etc.

Explanation of Solution
Plants face two challenges due to their lack of mobility. Plants have diploid and haploid life stages. The haploid stages allow the plants to reproduce sexually by the fusion of male and female gametes (fertilization). Getting sperms to eggs for fertilization can be one of the challenges for many plants living on land, especially if the plants are large or live in dry conditions. Some plants enlist the help of animals to carry the male gamete to the female gamete. As a result of their inability to move, another challenge which plants face is that they cannot run from or escape from predators. Plants develop other means of defense, including thorns and poisonous chemicals.
There are the two challenges which face by the plants due to their inability to move:
- Getting sperms to eggs for fertilization.
- Plants cannot run from or escape from predators.
