Answer:

c. They lack lignified vascular tissue

Explanation:

We know that forest consists of tall trees. In the tall trees the water and minerals are transported to the every part of tree through the lignified vasucular tissue. This tissue not only helps in transport within the tree but also provides some sort of mechanical strength due to the presence of lignin it its walls. On the other hand bryophytes are non-vascular plants which means they lack vascular tissue and thus a mechanism for long distnace transport of water and minerals is absent in them. So they can't be taller as a tree and thus can't form forest.

Answer:

a. It's a carrier protein doing facillitated diffusion

Explanation:

Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.

The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.
