Question

what helps the cell hold its shape if it does not have a cell wall?

Explanation:

In cells without a cell wall (like animal cells), the cytoskeleton (composed of microtubules, microfilaments, and intermediate filaments) and the cell membrane's structural properties help maintain shape. The cytoskeleton provides internal structural support, and the cell membrane's flexibility combined with cytoskeletal elements helps the cell retain its form.

Answer:

The cytoskeleton (along with the cell membrane's properties) helps the cell hold its shape if it does not have a cell wall.
