Cell walls are made out of cellulose and they give a sturdy structure to the cells (if you notice they have a rectangular shape)
D. Volcanic Rock
As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
<u>Answer:</u>
Loading bay on cell organelles is Cell Membrane.
<u>Explanation:</u>
It is the outermost layer or barrier of a cell organelle which surrounds the cell. It is made of a double layer of hydrophobic interiored and hydrophilic exterior ed fatty acids.
Inside the membrane there are structures like protein etc. that act as loading bay on cell organelles i.e they help to regulate what exits or enters through the membrane of the cell organelle. Hence, cell membrane is called the loading bay of cell organelles.
