Which of the following plants would you expect to grow lowest to the ground?

a. hornworts

b. cycads

c. ferns

d. horsetails

Among the listed plants above, the one that we can expect to grow lowest to the ground would be the hornworts. Hornworts are non-vascular plants which can be found both on water and land. Since these plants do not have a vascular system, it is hard for them to move water internally due to the force of gravity which explains why they cannot grow more above the ground.
