The hollow tubes of protein that help maintain the shape of the cell is what?
microtubules.... might be right
How does active and passive transport help maintain homeostasis?
They transport fluid/water/materials across the cell memebtane
What is consist of hollow tubes which provide support for the cell?
Microtubules are rigid hollow rods which help support and shape a cell. They undergo continual assembly and disassembly within the cell.
What is mesophill cell?
A cell which help in the transport of water and stomatal transpiration in plants
What are Microtubules?
it is buit by tubulin protiens.there are two types of tubulin protien. they are 1.alpha 2.beeta. they are very use full in cell devision.and they help to built cytosceleton.

What is the description of microtubule?
The description of microtubules is hollow rods or hollow cylindrical structures. They mainly help to shape and support the cell.
What are the functions of a microtubules?
help determine the cell shape, move chromosomes during cell division
Are microtubules an organelle?
Microtubules are cyclindrical shaped polymers that help maintain and stabilize cell structure. They also have a major role in the transportation of molecules within the cell. They are part of the cytoskeleton, and the cytoskeleton is considered to be an organelle. The microtubules are only a fraction of an organelle under the cytoskeleton.

Microtubules are rigid hollow rods which help support and shape a cell. They undergo continual assembly and disassembly within the cell.
What is a microtubule in a cell?
These are produced by centrioles that are located near the nucleus and they help cells divide. These produce the microtubules which make up the cytoskeleton (the thing which gives the cell support and prevents organelles from flying around).
What is the role of the microtubules?
Microtubules attach to the to a structure on the sister chromatids called the kinetochore. Throwing the chromosomes into an agitated motion moving them towards the center of the cell. Then during anaphase they will help with the migration of chromosomes to opposite ends of the cell.
What are the functions for centrosomes?
They help make microtubules.
What is the function of micro-tubules?
When it comes to mitosis, this process is facilitated by a subgroup of microtubules known as astral microtubules, which are microtubules originating from the centrosome that do not connect to a kinetochore. Astral microtubules develop in the actin skeleton and interact with the cell cortex to aid in orientation of spindles during cell division. They are organized around the centrosomes into radial arrays. Astral microtubules function in in tandem with specialized dynein motors, which are oriented with the light chain portion attached to the cell membrane and the dynamic portion which is attached to the microtubule. This allows for dynein contraction to pull the centrosome towards the cell membrane, thus assisting in cytokinesis in plants and animals. Microtubules act as conveyer belts inside cells. They help to move vesicles, granules and organelles like mitochondria, and chromosomes via special attachment proteins. Vesicles get attached to microtubule associated proteins and move along the microtubule conveyer belt. The microtubule associated proteins include kinesins and dynein which move along the microtubules in opposite directions. Kinesins move vesicles along towards the plus end and dynein moves towards the minus end. This is how vesicles are moved from one region to another. This is active transport and hence, requires the breakdown of ATP, though it is not yet known how the energy from ATP breakdown is converted into vectorial transport. Also, it is microtubules that join with other proteins to form more complex structures called cilia, flagella or centrioles. Microtubules also play a role in maintaining the cytoskeleton, that is, the basic structure of the cell. This is because, structurally, they are linear polymers of tubulin which is a globular protein present in the cytoplasm. Read more on cytoplasm function in a cell. This was all about the structure and function of microtubules in a cell. Microtubules functioning and formation can be disrupted by the use of certain drugs. This is the basis of using certain drugs like colchicine which help to treat cancer. These drugs inhibit polymerization by binding to tubulin and preventing its addition to the (+) ends. { Q. Does anyone know .... what do the microtubules form between the centrioles? A. They form Bridges. }
What does a microtuble do?
Microtubules are very important to Mitosis. They help to pull the chromosomes to the opposite ends of the cell during anaphase.
What is the purpose of microtubules in plants?
Microtubules are hollow fibre threads in plant cells which from the cell structure. They are only found in plant cells furthermore they help in the production of chlorophyll and are vital to the survival of a plant.
