Nuclear membrane

Plant Cell Nuclear Membrane

Is a membrane-enclosed organelle found in eukaryotic cells. The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes.

An essential component of metazoan cells. Next to providing mechanical support to the Nucleus, its involved in most nuclear activities including: DNA replication, DNA repair, RNA transcription, chromatin organization, cell cycle regulation, cell development and differentiation, nuclear migration, and apoptosis. Its composed of intermediate filaments and membrane associated proteins.

A diagram of the anatomy of the cell. Clearly labeled and colored so that the students can distinguish individual parts. High cognitive level.

The nucleolus is the central portion of the cell nucleus and consists of RNA. Its main role is RIBOSOME BIOGENESIS. (also occurs in Cytoplasm; where most cellular activities such as metabolic pathways including glycolysis, and cell division take place.)

The main difference between glycolipid and glycoprotein is that glycolipid is a carbohydrate-attached lipid whereas a glycoprotein is a carbohydrate-attached protein. Functionally, glycolipids facilitate cellular recognition while glycoproteins serve as receptors for chemical signals.

Nucleur envelope

Nucleus is the largest organelle in eukaryotic cells. It is surrounded by two membranes. Each one is a phospholipid bilayer containing many different types of proteins. The inner nuclear membrane defines the nucleus itself. In many cells the outer nuclear membrane is continuous with the rough ER and therefore the space between the inner and outer nuclear membrane is continuous with the lumen of the rough ER. The 2 nuclear membranes appear to fuse at the nuclear pores. These ring like pores…
