Is there a difference between cell division and reproduction?

What is the name of the groove that forms in the middle of a dividing plant cell

mrs_skeptik [129]

Plants have cell walls, so cytokinesis cannot go on with a cleavage furrow, but instead, a cell plate forms across the cell in the location of the metaphase plate.

There is no distinct groove along the cell plate as the cell divides because of the rigid nature of the cell plate or new cell wall.

A plant cell divides differently from an animal cell which forms a clear cleavage furrow because it only has a flexible cell membrane and not a rigid cell wall like plants.

The cell plate in plant cells is formed by membrane bound vesicles which migrate to the center of the cell where the metaphase plate used to be and fuse together to form a cell plate.

Which part of the cell theory do these results most support:

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\huge\textbf{Cell Theory}$

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,

All organism are composed of one or more cells

The cell is the structural and functional unit of life
It is a de novo structure, that means it COULD arise from non living thing which was incorrect.

It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,

Cells can arise only by a division of pre-existing cell. It is <u>NOT</u> a de novo structure.

Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

$\huge\textbf{Question:}$

<u>Flask 1</u>: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.
<u>Flask 2</u>: It is observed that there are micro-organism present because meat is not sealed but open.
<u>Flask 3</u>: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy path

These observations support the point that<u> cells could arise only by a division of pre-existing alive cells</u> because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.

In the ouchterlony test, if an unknown antigen contains only swine serum albumin, how many precipitin lines will form between it

VashaNatasha [74]

In the question in regard to the ouchterlony test if there is an unknown antigen containing a swine serum album, the number of precipitin line that will form is one which is the answer. It relies in between the wells of the antibodies for the bovine albumin and the wells of the bovine albumin.
