This serves a structural function. Bound by a double-layer nuclear membrane, the nucleus contains the cell’s genome—the main genetic instructions in the form of DNA ( deoxyribonucleic acid ). Eukaryotic cells display a wide variety of different cell morphologies. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus; numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria) several rod-shaped chromosomes Furthermore, these cells exhibit the presence of DNA inside the nucleus. Identify three structures which provide support and protection in a eukaryotic cell. This is the largest structure within the cell. X. X. Cell Structure and Function BIOLOGY 81 Notes MODULE - 1 Diversity and Evolution Table 4.1 Differences between Eukaryotic and Prokaryotic cells of Life Eukaryotic cell (eu = true, karyon = nucleus) Prokaryotic cell (Pro = early/primitive) 1. Prokaryotic cells are not as complex as eukaryotic cells.They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid.. Prokaryotic organisms have varying cell shapes. Which table correctly describes the functions of the cell structures listed? • Membrane-bound spherical structure that houses genetic material of eukaryotic cell • Contains dense fibrous material called chromatin –complex of DNA, histones, and other proteins –five types of histones form nucleosomes •H1, H2A, H2B, H3, and H4 –chromatin condenses into chromosomes during division 36 The stack of larger vesicles is surrounded by numerous smaller vesicles containing those packaged macromolecules. They have a variety of internal membrane-bound structures, called organelles, and a cytoskeleton composed of microtubules, microfilaments, and intermediate filaments, which play an important role in defining the cell's organization and shape. A typical prokaryotic cell is of a size ranging from 0.1 m i c r o n s (mycoplasma bacteria) to 5.0 m i c r o n s.. 1 m i c r o n or micrometer, μ m, is one-thousandth of a millimeter or one-millionth of a meter..

It is comprised of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals ().Even though the cytoplasm consists of 70 to 80 percent water, it has a semi-solid consistency, which comes from the proteins within it. Plasma Membrane. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The genetic material of eukaryotic cells is compartmentalized within the nucleus, which is surrounded by a double membrane called the nuclear envelope. They also comprise other membrane-bound organelles and cellular structures which carry out specific functions necessary for a cell to function properly. Function: … Eukaryotic Cells and Prokaryotic Cells . (In addition to the cell membrane, some eukaryotic cells, such as plant cells, also have a rigid cell wall surrounding the cell membrane.

However, there is a difference between the way it is stored in the cell. It is comprised of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals ().Even though the cytoplasm consists of 70 to 80 percent water, it has a semi-solid consistency, which comes from the proteins within it. Bacteria - One of the earliest prokaryotic cells to have evolved, bacteria have been around for at least 3.5 billion years and live in almost every imaginable environment.
