This is one of the most popular laboratory practices, we do it since we are in high school and it is the starting point to learn about cell organization, with it we can see the main parts of a cell, here we are going to see the nucleus, the plasma membrane and cytoplasm, and I cannot fail to mention that we are going to use a chemical compound to stain the cell!🧫🔬
Esta es una de las practicas de laboratorio mas populares, la realizamos desde que estamos en la secundaria y es el punto de partida para conocer la organizacion celular, con ella podremos ver las principales partes de una celula, aqui vamos a ver el nucleo, la membrana plasmatica y el citoplasma, y no puedo dejar de mencionar que vamos a utilizar un compuesto quimico para teñir la celula!🤓👨🎓
PREPARATION?🧫👨🎓/PREPARACION??👨🏫🔬
The first thing we will do is use a new and clean swab, we will introduce it in the innermost area of our cheeks, on both sides of our face, then we remove the swab and rub it on a sheet😮💦
Lo primero que haremos es utilizar un hisopo nuevo y limpio, vamos a introducirlo en la zona mas interna de nuestras mejillas, de ambos lados de nuestra cara, luego retiramos el hisopo y lo frotaremos en una lamina👄👅
Next we are going to place water on the slide of the slide and on top we are going to drop a sheet of the coverslip, I did the experience observing the cells without being stained and another experience applying methylene blue!😮😮
A seguir vamos a colocar agua en la lamina del portaobjeto y encima vamos a dejar caer una lamina del cubreobjeto, yo hice la experiencia observando las celulas sin estar teñidas y otra experiencia aplicando el azul de metileno!😅💙💦
Then I used the smallest objective that is 5x + 10x and I increased the objectives until I reached the cell, it looks like this, but there is a problem ... It is not so easy to differentiate the parts ... That is why the dye to stain the core.🤔
Luego utilice el objetivo mas pequeño que son 5x+10x y fui aumentando los objetivos hasta llegar a la celula, ella tiene este aspecto, pero hay un problema... No es tan facil de diferenciar las partes... Por eso se añade el colorante para teñir el nucleo. 😮

We are in the presence of a eukaryotic cell, that is, an animal cell! We can differentiate it from the vegetable because there are no chloroplasts, we also do not see vacuoles and other distinctive characteristics! Then I show you in another post what a plant cell looks like! Let's begin to define the nucleus, let's say that it is the epicenter of the cell and here the genetic information or DNA is stored. Due to the chemical properties of methylene blue it can pass through the membrane and stain the nucleus!😁😁
Estamos en presencia de una celula eucariota, osea una celula animal! podemos diferenciarla de la vegetal porque no hay cloroplastos, tampoco vemos vacuolas y otras caracteristicas distintivas! luego te muestro en otro post como luce una celula vegetal! comencemos a definir el nucleo, digamos que es el epicentro de la celula y aqui se almacena la informacion genetica o ADN. Debido a las propiedades quimicas del azul de metileno puede pasar por la membrana y teñir el nucleo!💙💙
Then we have the plasma membrane that surrounds the cell and keeps everything in its "place" gives stability and helps the incorporation and exit of substances! let's say it's semi-permeable💥💥
Luego tenemos la membrana plasmatica que envuele la celula y mantiene todo en su "sitio" da estabilidad y ayuda a la incorporacion y salida de sustancias! digamos que es semipermeable💦💦
Finally, the cytoplasm would be that internal environment of the cell, surrounds the nucleus and here all the cellular organelles such as mitochondria, ribosomes are arranged.🧫🔬
Por ultimo el citoplasma seria ese medio interno de la celula, rodea el nucleo y aqui se disponen todos los organelos celulares como mitocondria, ribosomas.👨🎓👨🎓
Well my friends, I hope you have learned something new today, I would like to add that the normal thing is that the cells are together that is how they remain when they are alive, thank you for voting and evaluating my post, hugs and do not miss another scientific study!❗✅
Bueno mi amigos, espero hayan aprendido algo nuevo hoy, me gustaria agregar que lo normal es que las celulas esten juntas asi es como permanecen cuando estan vivas, gracias por votar y valorar mi post, abrazos y no te pierdas otro estudio cientifico! 💯💯
THANK YOU FOR YOUR VOTE AND YOUR VALUABLE OPINION (the photos is my property) 🙂🧠🦾👍
