Which feature do prokaryotic and eukaryotic cells share a nucleolus B cytoplasm C nuclear membrane D membrane bound organelles?

Which feature do prokaryotic and eukaryotic cells share a nucleolus B cytoplasm C nuclear membrane D membrane bound organelles?

The correct option is B. Prokaryotic cells are primitive cells which have no true nucleus and membrane bound organelles while eukaryotic cells are cells that have true nucleus, membrane bound organelles and well defined structures and layouts.

Which feature do prokaryotic and eukaryotic cells share?

Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.

What do prokaryotic cells lack a cell membrane B cytoplasm C cell wall D membrane bound nucleus?

Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Do prokaryotes and eukaryotes have a nuclear membrane?

In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).

Why do mitochondria have two membranes?

The inner membrane folds over many times and creates layered structures called cristae. The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.

How are Golgi bodies formed?

The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.

What cells have lots of Golgi bodies?

The number of sets of Golgi apparatus in a cell can be as few as 1, as in many animal cells, or many hundreds as in some plant cells. Specialised secretory cells contain more sets of Golgi apparatus than do other cells.
