What is the size difference between a cellular nuclei and an atomic nuclei?
Cellular nuclei, found in eukaryotic cells, are significantly larger than atomic nuclei. A typical cellular nucleus has a diameter of about 5 to 10 micrometers, while atomic nuclei measure on the order of femtometers (10^-15 meters), making them roughly a million times smaller than cellular nuclei. This size difference highlights the vast scale of biological structures compared to atomic components.
Do plant nucleus's have DNA?
Yes, plant nuclei have DNA. The DNA in plant nuclei contains the genetic information that determines the plant's traits and characteristics. This DNA is organized into structures called chromosomes and is responsible for controlling plant growth, development, and reproduction.
What is iodine used to see when using a microscope?
Iodine is used as a stain to visualize cellular structures, such as nuclei and starch granules, in biological samples when using a microscope. It can help highlight these structures by binding to specific molecules and enhancing their contrast against the background.
DNA in the nucleus is found in structures called .?
chromosomes
What Cells do not have have Nuclei or Mitochondria?
Red blood cells do not have nuclei or mitochondria.

What are the structures that make up the intersposed nucleus?
globose and emboliform nuclei
What is the opposite of a prokaryotes cell?
Eukaryotic cells are cells that contain nuclei and have complex structures. Prokaryotes are generally unicellular and lack nuclei.
Cells with organized nuclei?
Cells with organized nuclei are typically eukaryotic cells, which have a defined nucleus surrounded by a nuclear membrane. The organized nucleus contains the cell's genetic material in the form of chromosomes, which are responsible for regulating cellular functions and inheritance. This distinct nuclear structure is a key feature that sets eukaryotic cells apart from prokaryotic cells.
What kind of organelles or structures can be found in both plant and animal cells?
Nuclei.
DNA in the nucleus is found in structures called .?
chromosomes
Do prokaryote structures have cell membranes?
Yes thy do. They just lack True Nuclei
What are the effects of safranin stain on the cell?
Safranin stain is commonly used in histology to stain acidic cell components such as nuclei, cartilage, and mucin. It appears red or pink in color and can help differentiate these structures from other cellular components when viewed under a microscope.
Are there visible nuclei in the tissue?
Yes, nuclei are typically visible in tissue samples when viewed under a microscope. Nuclei contain DNA and are stained with dyes to make them more visible for analysis. They appear as dark, round structures within the cell.
Biological stains used for plants?
Common biological stains used for plant studies include iodine solution for starch detection, safranin for staining cell walls and nuclei, and toluidine blue for highlighting lignified cell walls. These stains help researchers visualize and study cellular structures and processes in plants.
