Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The cytoskeleton is made from thread-like filaments and tubules
A
False
B
True
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -A framework of protein scaffolds called the cytoskeleton provides the cytoplasm and the cell with structure. The cytoskeleton consists of thread-like filaments and tubules that criss-cross the cytoplasm. You can see these filaments and tubules in the cells in Figure 5.5.

Detailed explanation-2: -The cytoskeleton is a highly organized framework of protein filaments and tubules that criss-cross the cytoplasm of a cell. It gives the cell structure and helps hold cell structures (such as organelles) in place within the cytoplasm.

Detailed explanation-3: -The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts. In addition, they provide a basis for movement and cell division.

Detailed explanation-4: -Which statement about the cytoskeleton is true? Components of the cytoskeleton often mediate the movement of organelles within the cytoplasm.

Detailed explanation-5: -This structure acts as both muscle and skeleton, for movement and stability. The long fibers of the cytoskeleton are polymers of subunits. The primary types of fibers comprising the cytoskeleton are microfilaments, microtubules, and intermediate filaments.
