Cell Theory and Eukaryotic vs

The three main principles of the cell theory are: 1) Cells are the basic unit of life, 2) All organisms arise from cells, and 3) All cells come from pre-existing cells.

The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus, while prokaryotic cells do not have a nucleus.

The function of the mitochondria in a eukaryotic cell is to perform cellular respiration, converting glucose into ATP to provide energy for the cell.

The rough endoplasmic reticulum is the site of protein synthesis in a eukaryotic cell. mRNA, transcribed from DNA in the nucleus, is translated at the rough ER to produce proteins.

The function of lysosomes in a cell is to break down and recycle cellular waste, as well as to remove non-functional organelles.

The nuclear envelope contains the inner and outer membranes and the nuclear pores. The inner and outer membranes separate the cytoplasm from the nucleoplasm, while the nuclear pores allow certain compounds in and out of the cell, such as proteins and RNA polymerases.

The nucleolus is responsible for ribosome assembly and is located at the center of the nucleus. It is densely packed with regions of DNA that produce ribosomal RNA.

The chromosomes are contained within the nucleus of a cell.
