Procedimientos:
Hacer un pequeño corte transversal, y proceder a
desechar luego cortar por segunda ver y este corte que debe ser muy fino, si es necesario se debe realizar varias veces, colocar la
muestra sobre un portaobjetos y cubrir con una laminilla comprimir suavemente con los dedos para eliminar las burbujas que se forman. Observar primeramente con diafragma cerrado en 10X y luego en 40X.
Observación:
Tomar la muestra fue muy difícil debido a que el corte debía ser
extremadamente fino, lo que se observa son pequeñas celdas deformes
unidas y cromoplastos.
En el objetivo
de 10X solo pude apreciar, las paredes celulares, los cromoplastos que eran de
un naranja muy bajito, los residuos, burbujas de aire.
En 40X se puede observar las células que son ovaladas, transparentes y los cromoplastos que son
como manchas de color naranja que están en cada célula dándoles el color que caracteriza a las zanahorias.
