Strong stiff and made up of cellulose?
Cell walls in plant cells are strong, rigid structures composed mostly of cellulose. These walls provide structural support and protection for the cell, ensuring it maintains its shape. Additionally, cell walls allow for communication and exchange of materials between neighboring cells.
What does a valuclue tdo for thecell?
A vacuole serves a variety of functions in a cell, such as storing nutrients, waste products, and water. It also helps maintain pressure within the cell to provide structural support. Additionally, vacuoles can aid in digestion and recycling of cellular components.

How did schwann contribute to the cell theory?
Schwann recognized the cell as the basic unit of animal structure. He advanced thecell theory in plants and took the theory over to animals. In 1839 Schwann proposed that all organisms are composed of cells. Together with Matthias Schleiden he formulated the cell theory of life.
Pinocytotic vesicle function?
Pinocytosis is " cell drinking, " so the function of the pimocytic vesicle is it's pinched off status formed when the cell membrane invaginates, forms a pocket, and the vesicle is formed and taken into the cell proper. Some nutrients come along for the ride.
In what phase of mitosis do the sister chromatids move to opposite poles of the cell?
In the third stage, anaphase, the sister chromatids ofeach replicated chromosome begin to separate.Fibers pull the centromere apart and chromatidsmove away from each other, toward opposite ends of thecell.
