Land plants no longer required water as a medium for reproduction with the evolution

1) Gymnosperms have developed over the course of its evolution, structures that solved the main limitations present in the Pteridophytes in relation to sexual reproduction, in the terrestrial environment.

2) The organisms that have adapted fully to the terrestrial environment feature adaptations in the body to retain water, thus avoiding dehydration.

3) about Pteridophytes:Vascular tissue: water and minerals and organic
 material.
Vascular tissue: increasing efficiency in the transport of water and mineral salts with increased plant growth.Dependence on water for fertilization with anterozoides furniture.

hope this helps!

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
