mammalian cells are negatively charged where as the tissue culture flask are coated with positively charged chemicals. Hence the cells are binding to it
A culture of living cells is often grown in a container called a culture flask or petri dish. These containers provide a controlled environment that supports cell growth and multiplication, typically containing a nutrient-rich medium. Depending on the type of cells and the specific experiment or application, different types of containers and media may be used.
plant tissue culture or cell culture:-it is the technique of in vitro, culture in which isolated plant cells, tissues, organs or even entire plant are subjected to grow in nutrient media in glass containers(tubes,conical flask,petri dishes) under aseptic conditions. Aseptic culture of plant may be of the following types as:-(a) ORGAN CULTURE:- These are cultures of isolated plant organs including cultures derived from root tips,stem tips,leaf primordia or immature part of flowers and immature fruits.(b) EMBRYO CULTURE:- These are culture of isolated immature or mature embryos.(c) CALLUS OR TISSUE CULTURE:- These are culture of tissue arising from disorganized proliferation of cells from segment of plant organs.tissue or callus culture are , generally grown on solid medium as amass of cells.(d) SUSPENSION CULTURE:- These are often called cell cultures, as they represent a lower level of organisation than tissue or callus culture. suspension culture are in vitro cultures of isolated cells and very small cell groups remaining dispersed as they grow in excited liquid media.
The working volume in a 500ml shake flask is typically around 20-25% less than the total flask volume, so it would be around 375-400ml. This allows for proper aeration and mixing of the culture without overflowing during shaking.
If the neck of a sterilized swan-necked flask were broken, the flask would be exposed to contaminants in the air, negating the purpose of the swan neck design to prevent microbial contamination. This would likely compromise the sterility of the contents in the flask, leading to potential contamination and spoilage of the culture inside.

Another word for a triangular flask is a conical flask.

UMMM....A bottle? i think it's called a decanter
cells came from nonliving things
what is a flask for what is a flask for
Human liver tissue for research is procured from donated human liver. It is obtained through established clinical or tissue-procurement networks rather than collected directly by a research laboratory. The tissue collection process, that is, consented donors, surgical resections, transplant-related sources, or accredited tissue banks depends on the research objective and research design. The exact source can vary based on factors such as donor eligibility, tissue quality, availability, and the requirements of the study. It is crucial to maintain ethical regulations to procure human liver tissue. This involves gaining informed consent and clearance from the relevant ethical committee. Other information including donor age, sex, medical history, and tissue collection details are noted in detail by the researchers. The type of liver material you need also makes a difference. For example, fresh or cryopreserved liver tissue may be used for histology, molecular studies, or primary hepatocyte isolation. Other researchers may need processed biological models such as human liver microsomes (HLM) or human liver S9 fractions, which are prepared from liver tissue and are commonly used in drug metabolism, ADME, and toxicology studies. For isolation of the human liver tissue, the tissues are homogenized in an adequate buffer solution maintained at appropriate pH. The tissues are subjected to enzymatic digestion (collagenase or trypsin) to isolate single cells. The digested tissues are mixed with complete culture media and centrifuged to obtain the tissue pellet, which is further seeded in the cell culture flask or plates. The cells are incubated under adequate conditions with a temperature of 37 °C, 5% CO2, and relative humidity.
He disproved that living cells come from nonliving things.
