What is it called when part of a cell membrane closes around a molecule to allows the molecule to enter the cell?
This is called endocytosis.
What organelle allows the cell to maintain its shape?
the cell membrane or cell wall, depending on the type of cell. microtubules also play a part in giving the cell structure.
What allows a plant to make glucose?
The process of photosynthesis, as catalyzed by chlorophyll or an equivalent molecule.
What characteristics of the water molecule allows it to play an extensive role in many biological reactions?
It's a polar molecule: a molecule that has a net dipole moment due to its having unsymmetrical polar bonds. Unequal sharing of electrons makes water a polar molecule.
What property of water allows bicarbonate NaHCO3 to dissolve into solution?
Water is a polar molecule, meaning that the partially charge ends of the water molecule will attracted the oppositely charged ions in the NaHCO3
What is the role of kinetochores and microtubules?
Kinetochore allows the attachment of chromosomes to the spindle fiber, which is made ofmicrotubules.Microtubules allowssister chromatidsto separate duringcell division.
What evidence supports the observation that sister centromeres behave as a unit during meiosis you?
Data from electron microscopy studies suggests that the centromere/kinetochore complex of sister chromatids is compacted. The kinetochores then capture microtubules in a way that allows the kinetochores of sister chromatids to function as a single unit.
What allows a cell to change its shape and move its organelles?
microtubules
What type of molecule allows a blade of grass to stand up straight?
Turgor pressure is what allows a blade of grass to stand up straight. This is a type of a molecule.
What is the molecule that allows plants to capture energy from sunlight?
Chlorophyll

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 organelle allows the cell to maintain its shape?
the cell membrane or cell wall, depending on the type of cell. microtubules also play a part in giving the cell structure.
Is h2 polar or nonpolar molecule?
H2S is considered a polar molecule. Its construction allows it to have dipoles and dipole moments, which makes it polar.
