Answer:

There are many environmental factors that affect the opening and closing of stomata, mainly water availability.  

Stomata regulate gas exchange and water flow. The exchange of carbon dioxide between the plant and the  medium is controlled by the opening and closing of stomata. When the stomata open  increases the amount of carbon dioxide that enters the plant, but also  the amount of  water loss increases. For this reason during the night the stomata are closed to avoid unnecessary loss of water.

In dry ecosystems the leaves have fewer stomata to reduce the loss of

water generated by high temperatures.

Describe how Schwann cells form the myelin sheath and the neurilemma.
-Dominant- [34]

Answer:

Schwann cells or neurilemma cells are the cells which form the myelin sheath around neuronal axons in the peripheral nervous system (PNS) only.

Neurilemma is the collective term used for cytoplasm and nuclei present around the myelin sheath which helps in the regeneration process of nerves.

A Schwann cell surrounds the axon, invaginate it and the plasmalemma of the Schwann cells joins and from a double membrane structure called mesaxon. This mesaxon starts wrapping the axon in spiral fashion and cytoplasm start condensing into the compact myelin sheath.
