1. The right answer is Vacuoles.
Vacuoles is a characteristic organelle found in plants and fungi.
In addition to the important role for cell turgor (regulation of the shape of the cell by osmotic pressure), the huge vacuole that exists in most cells plays multiple roles of waste storage, sometimes reserve and most often maintenance of cell composition.
2. The right answer is cell wall.
The wall is the outermost envelope of the plant cell. It is essentially composed of carbohydrate polymers, cellulose and pectin, proteins and possibly other compounds of phenolic nature (lignin and suberin). The wall is composed of three essential parts: the middle lamella, the primary wall and the secondary wall.

b) The white matter
c) gray matter
Explanation:
The three main parts of cerebral hemispheres are
a) Myelinated nerve fibers
b) The white matter
c) Gray matter
The nerve fibers of the white matter are responsible for connecting the functional parts of cerebral cortex while the gray matter is further divided into four surface folds/lobes with each lobe associated with a specific activity. Such as frontal lobe take cares of motor activity and speech, parietal lobe is responsible for touch and position sensation, occipital lobe for vision and temporal lobe for hearing.
