Increasing the cell's volume would reduce the efficiency of the diffusion of materials through the plasma membrane into the cytoplasm of the cell.
On the other hand, increase the surface area and decreasing the volume oft the cell would increase the rate of diffusion across the plasma membrane.
Answer: Glial cells called ASTROCYTES help maintain the blood-brain barrier, whereas SCHWANN CELLS create the myelin that envelopes axons
Explanation: Glial cells are specialized cell that are found in both central and peripheral nervous systems, that surrounds the neurones, providing them with support and insulation. There are different types of Glial cells these includes:
- Astrocytes: they maintain the blood brain barrier.
- Schwann cells: create the myelin that envelopes axons of the peripheral nervous system neurones.
- satellite cells: These cells help regulate the external chemical environment of neurones.
- Microglia: they clean up cellular debris through phagocytosis.
- Oligodendrocytes: create the myelin that envelopes axons of the central nervous system
Meristematic tissue have the ability to
divide themselves. It is the primary site for cell division and cell
differentiation. It produces the new cells and are called growing tissue in
plants. The new cells may or may not divide. It is the source of the regenerative
potential of the plant.

Cancerous cells can originate anywhere in the
body and can spread into or invade adjoining tissues. It keeps growing and dividing
relentlessly to form lumps. It can also break off and travel to distant
tissues. Cancer cells rejects signals from other cells.</span>

Lipids are a class of organic compounds, which suits best under the column macromolecules on the hierarchy of biological organization.
Biological organization refers to the hierarchy of composite biological systems and compositions, which illustrate life using a reductionistic method. The conventional hierarchy moves from an atom to more complex biospheres.
Each of the level in the hierarchy signifies an enhancement in the organizational complexity, with each component being mainly comprised of the previous basic unit level.
