Answer & explanation:
The cell was discovered in 1669 by the English scientist Robert Hooke when looking at a piece of tissue in a two-lens microscope. Hooke was able to visualize small cavities in the experiment piece, then naming such cell cavities.
Only a century and a half after the discovery of the cell, that the Cell Theory was launched, replacing the theory of spontaneous generation (or abiogenesis).
Before that, many scientists were already busy understanding the structure and functioning of the cell, generating knowledge that became fundamental to the development of biology, specifically cytology, a branch of science that studies the structure, functions and development of cells.

Mitosis occurs after interphase (which is the phase that takes the longest) and is occurring all the time in your cells. Sometimes a cell will not go into a state of mitosis if an error is found during the interphase process (if it does, it's cancerous) . Some cells don't go through the process of mitosis, like neurons. But once a cell passes interphase without any errors, it will go into mitosis then cytokinesis. The process takes about one day and occurs when your body is repairing itself or if you're growing and developing. So yes, it happens all the time, just not in every single cell; just in most cells.

Answer:
Blutzellen. Blut enthält viele Arten von Zellen: weiße Blutkörperchen (Monozyten, Lymphozyten, Neutrophile, Eosinophile, Basophile und Makrophagen), rote Blutkörperchen (Erythrozyten) und Blutplättchen. Blut zirkuliert durch den Körper in den Arterien und Venen.
Explanation:
Blut besteht hauptsächlich aus Plasma, aber 3 Haupttypen von Blutzellen zirkulieren mit dem Plasma: Blutplättchen helfen dem Blut bei der Gerinnung. Durch die Gerinnung wird verhindert, dass Blut aus dem Körper fließt, wenn eine Vene oder Arterie gebrochen ist. Thrombozyten werden auch als Thrombozyten, rote Blutzellen (RBCs) oder Erythrozyten bezeichnet.
Blutplättchen oder Thrombozyten.
fünf Arten von weißen Blutkörperchen (WBCs) oder Leukozyten. Drei Arten von Granulozyten. Neutrophile. Eosinophile. Basophile. Zwei Arten von Leukozyten ohne Granulat im Zytoplasma.
