Which pair of organelles works together to give structure and support in animal cells?
Montano1993 [528]

Answer:

Cell membrane and cytoskeleton

Explanation:

The cell membrane is the outer covering that encloses the cell contents and regulates movement of materials in and out of the cell. the cell membrane gives the cell its structure. Cytoskeleton provides support to the cell and  include three types of small networks:

Actin filaments: - are flexible double strands of the protein actin . They lead the intracellular movement of organelles  and molecules  and stabilize mechanically the plasma membrane .

Microtubule: - are rigid hollow cylinders of the proteins α- & β-tubulin

They are responsible for the position and stability of ER and  Golgi-Apparatus , help to divide & move chromosomes during mitosis  and organize the growth of the cell wall .

Intermediate filaments: - are robe like fibres of different proteins which give

mechanical support
