What else can I help you with?
Excess water is pumped out of a paramecium by means of?
Contractions of contractile vacuoles, which are specialized structures that collect and expel excess water from the cell through a process called osmoregulation.
What are 3 cytoskeletal structures which help support cells?
Three cytoskeletal structures that help support cells are microtubules, actin filaments (microfilaments), and intermediate filaments. Microtubules provide structural support and serve as tracks for cellular transport, actin filaments are involved in cell shape and movement, while intermediate filaments provide mechanical strength to cells.
Where cytoskeletal proteins synthesized?
All the proetins ncluding cytoskeletal machinery are synthesized in cytoplasm. This is because cytoplasm alone has ribosomes, tRNA and amino acid pool. mRNA need to exported out of nucleus prior to the synthesis of protein.
What is non-contractile?
Non-contractile refers to tissues or structures that cannot undergo contraction, such as certain cells, like nerve cells, or non-muscle tissues like bone or cartilage. These tissues do not have the ability to actively generate force or movement through contraction.
What is during cytokinesis which animal cell parts are allocated to the new animal cells?
During cytokinesis in animal cells, the cytoplasm is divided between the two daughter cells through the formation of a cleavage furrow, which is facilitated by a contractile ring of actin and myosin filaments. Key organelles, such as mitochondria and endoplasmic reticulum, are distributed to ensure each new cell has the necessary components for function. Additionally, other cellular structures, like centrioles, are also allocated to provide support for future cell division. This process ensures that both daughter cells are equipped to survive and grow independently.
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.
Which cytoskeletal structures on the lining of the respiratory tract are needed to sweep dust and debris away?
cilia
What is the cytoskeletal filaments?
Cytoskeletal filaments are long, slender protein structures found in the cytoplasm of cells. They provide structural support, help maintain cell shape, facilitate cell movement, and are involved in intracellular transport. The three main types of cytoskeletal filaments are actin filaments (microfilaments), intermediate filaments, and microtubules.
What is non contractile muscle structures called?
series-elastic elements

Is the smallest of the cytoskeletal elements?
The smallest of the cytoskeletal elements is microfilaments, also known as actin filaments. These structures are typically about 7 nanometers in diameter and are composed primarily of the protein actin. Microfilaments play crucial roles in various cellular processes, including muscle contraction, cell shape maintenance, and motility. They are essential for cellular functions and contribute to the overall dynamic nature of the cytoskeleton.
What is a cytoskeletal that pulls chromosomes apart?
The mitotic spindle is a cytoskeletal structure that pulls apart chromosomes during mitosis. It is composed of microtubules that attach to the chromosomes and exert force to ensure accurate separation of genetic material.
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.
