The correct option is, (D) microtubules.
- The cytoskeleton of a cell, which provides the internal support structure for the cell, is primarily made up of proteins, which are the building blocks of microtubules.
What is the function of the endoplasmic reticulum?
- In general, the endoplasmic reticulum's job is to make proteins so that the remainder of the cell can operate.
- It can be smooth or rough.
- Ribosomes, which are tiny, elongated organelles with a round shape, are found on the rough endoplasmic reticulum and are responsible for producing those proteins.
Which of following organelles help with cellular movement?
- The cytoskeleton not only performs this structural function, but it also controls how cells move.
- These involve not just the internal movement of organelles and other structures (such mitotic chromosomes) through the cytoplasm, but also the motions of whole cells.
Which organelle provides energy for the cell?
- Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
- Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Hence, microtubules is used as cellular support for cells and unicellular organisms.
