Plasmodesmata
The earth can be considered a closed ecosystembecause it does not necessarily allow other materials to enter, and does not release materials.
leaves
The process in which gases enter the leaves of the plants is called respiration.
They must have structures that allow them to obtain water or other nutrients from their surroundings, retain water, transport materials in their bodies, support their bodies, reproduce and leaves for photosynthesis
Permeable if anything can go through or semipermeable if only certain things can go through it.
Plasmodesmata
Materials that do not allow electric currents to pass are called insulators.
Translucent materials allow some light to pass through. Transparent materials allow most or all light to pass through.
Transparent materials allow light to freely pass through them. Translucent materials also allow light to pass through them, but change the colour of the light.
permeability
They are called opaque materials.

Those are called insulators.
They are usually called semi-conductors.
