They are found in photosynthetic cells. But they are absent in prokariyotes
Vacuoles are only present in plant cells. Animal cells have small pores called vesicles.
Dictyosomes are present in plant cells
Protists are Eukaryotic cells, so they will have a nucleus (and a nucleolus), like humans.
No mitochondria are not present in prokaryotes. They are present in only in eukaryotes.
Endocervical and/or squamous cells are normal on a pap smear. This notation on your result means the test was complete.
If the endocervical cells in the pap test results are positive, then it means having a positive outlook that can lead to a greater sense of well being.
No endocervical cells on a pap smear means that the pap was not completely adequate. This result can occur if the opening of the cervical canal is very narrow. It does not typically indicate a problem, but may require repeat testing soon.

There is no danger from a pap result with absent endocervical cells. This notation just means that there was incomplete sampling. The cause may be hormonal, or anatomical, but it means nothing for your health. Repeat the test as recommended by your health care provider.
Searching with the same question, I found this answer at: http://www.drfeelgood.com.au/articles/tests/understanding_pap_smears.htm The canal inside the cervix (endocervical canal) which leads to the uterus cavity is lined by cells which make a transition to become those of the internal lining of the uterus. The transition point can easily vary from woman to woman and even from time to time in the same woman. This transition is not visible with the naked eye. One theory is that the abnormal calls occur at the point of transition. This is why a doctor aims to get a sample from the endocervical canal. A pap smear result routinely reports the presence or absence of these endocervical cells. The aim is to have a representation of endocervical component ensuring that the transition point has been past. It is important to check with your doctor that the endocervical component is present. I always use a brush inserted into the cervix canal when I do a pap smear . I tell the patient whether I feel I have adequately sampled the area. If there is no endocervical component present I discuss with the patient that forcing the brush up any further may not be appropriate. We discuss risks versus benefits of screening tests and decide together whether we will take any further action on the matter.
what instrument is used to obtain a endocervical tissue
Endocervical curettage-- Biopsy performed with a curette to scrape the mucous membrane of the cervical canal.
Cells are not part of cells, your question makes no sense.
ECC stands for endocervical curettage. During a colposcopy, ECC is typically taken as a biopsy of the endocervical canal.
