In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.

Explain why eukaryotes need to use mitosis in cell division when prokaryotes do not. – Eukaryotes need to use mitosis in cell division because they have nucleus that contain chromosomes, while prokaryotes don’t contain a nucleus. Chromosomes are structural DNA, while chromatids are the exact duplication of chromosomes.

During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

Cell division in eukaryotic organisms is necessary for development, growth, and repair of the organism. Therefore, prior to cell division, the eukaryotic cell’s complete genome must be copied, a process known as DNA replication, ensuring that each daughter cell receives a complete set of the genome.

Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles. All of these cell parts must be duplicated and then separated when the cell divides.

The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs.

Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.

Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The cytoplasm is all the contents of the cell inside the cell membrane, not including the nucleus.

All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4) ribosomes.

It includes features from all cell types. A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.

All cells have these four parts in common: a plasma membrane, cytoplasm, ribosomes, and DNA. Plasma membrane – also known as cell membrane.

Parts common to all cells are the plasma membrane, the cytoplasm, ribosomes, and genetic material.

All cells are surrounded by a membrane and contain genetic material but otherwise are structurally diverse. All cells have structural and functional similarities. Structures shared by all cells include a cell membrane, an aqueous cytosol, ribosomes, and genetic material (DNA).

A similarity is a sameness or alikeness. When you are comparing two things — physical objects, ideas, or experiences — you often look at their similarities and their differences. Difference is the opposite of similarity. Both squares and rectangles have four sides, that is a similarity between them.

Even though there are many different types of cells, they all share similar characteristics. All cells have a cell membrane, organelles organelles, cytoplasm, and DNA. 1.
