What are 3 cytoskeletal structures which help support cells?
Microtubules, microfilaments, intermediate filaments
What structures form on plant cells during cytokinesis?
Cleavage Furrow
In the paramecium what pumps water out of the cell?
active transport, the water is pushed out through contractile vacuoles against its natural flow. Osmosis states that water flows from a higher concentration to a lower concentration, but the paramecium has less water and water is still being pushed out.
Do some single-celled organisms have special structures to pump excess water?
The structure is called the contractile vacuole. It can pump water out of the cell when there is too much. This way, the excess water won't cause it the cell to burst. They can be found in both animal and plant cells.
Mitosis and cytokinesis?
Mitosis is the division of the DNA between daughter cells. Rope-like structures called microtubules actually grab the chromosomes and pull each copy to separate sides of the cell. Cytokinesis is the physical separation of the cells - a ring of actin (a muscular kind of fiber) pinches the cell into two and creates two separate cells. Mitosis and cytokinesis together are called the M-phase of the cycle.
What cytoskeletal element involves in moving intracellular structures?
The cytoskeletal elements involve in the moving intracellular structures are the microfilaments. They are small rod-like structures found in most eukaryotic cells.
What are 3 cytoskeletal structures which help support cells?
Microtubules, microfilaments, intermediate filaments
Which cytoskeletal structures on the lining of the respiratory tract are needed to sweep dust and debris away?
cilia
What is non contractile muscle structures called?
series-elastic elements
What structures form on plant cells during cytokinesis?
Cleavage Furrow
What is myofilament?
Myofilament are long tubular structures inside of muscle cells that are made up of shorter contractile sections called sarcomeres.
What is a cytoskeletal that pulls chromosomes apart?
CentriolesCentrioles are log-like structures that appear during cell division in animal cells and pull the chromosomes apart.
In the paramecium what pumps water out of the cell?
active transport, the water is pushed out through contractile vacuoles against its natural flow. Osmosis states that water flows from a higher concentration to a lower concentration, but the paramecium has less water and water is still being pushed out.
What is inert tissue?
Inert tissues include all structures that would not be considered contractile or neurological, such as joint capsules, ligaments, bursae, blood vessels, cartilage and dura matter.
What is the contractile elements of the cytoskeleton?
Microfilaments Microfilaments support the microvilli, they are involved in muscle contraction and other cell motility, endocytosis, and cell division... Anatomy & Physiology/fourth edition
How does osmoregulation occur in unicellular organisms?
Osmoregulation in unicellular organisms is by active transport. For example in Paramecium - osmoregulation is done by organelles called contractile vacuoles. These contractile vacuoles are spherical shaped structures surrounded by a series of radiating ducts. These ducts collect water and pump it into the central area by means of contractile fibres that contract and force the water into the center. When the vacuoles are full the unicellular organism contracts forcing the water outside the cell.

The structure is called the contractile vacuole. It can pump water out of the cell when there is too much. This way, the excess water won't cause it the cell to burst. They can be found in both animal and plant cells.
