Was the nucleus visible in Lactobacilli? Why?
Chromatin- granular material visible within the nucleus
The term "nucleus" can refer to different contexts, but in biology, it is still visible in cells under a microscope, particularly in eukaryotic cells where it houses genetic material. In astronomy, the nucleus is visible in comets, representing the solid core that releases gas and dust to form a visible atmosphere or tail when near the Sun. In physics, the atomic nucleus remains a fundamental concept in understanding atomic structure and nuclear reactions.
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
The largest, and most easily visible organelle found in MOST cells is the nucleus. It is large and dark staining, and quickly seen in a microscope. However, only eukaryotic cells have a nucleus. Prokaryotic cells don't have organelles at all.
No, nuclei are not visible in Oscillatoria and Gloeocapsa because they lack a true membrane-bound nucleus. They are prokaryotic organisms, meaning their genetic material is not contained within a nucleus but instead floats freely in the cytoplasm.
The genetic material is in the nucleus to protect it.
Chromatin material is contained within the nucleus.
The nucleus is what contains the genetic material of a cell.
