are plant cells dna free in the cytoplasm

Plant cells key similarities animal cells and plant cells are eukaryotic cells.

Are plant cells dna free in the cytoplasm. Prokaryotic cells such as bacteria and archaeans do not have a membrane bound nucleus. Prokaryotes can carry extrachromosomal dna elements called plasmids which are usually circular. The dna is enclosed within the nucleus an enveloped membrane structure at the center of the cell. The nucleotides in dna are each composed of a nitrogen containing base adenine guanine cytosine or thymine a five carbon sugar deoxyribose and a phosphate group.

Plants cells have dna that helps in making new cells hence enhancing the growth of the plant. Plant and animal cells are eukaryotic meaning that they have nuclei. In figure 1b the diagram of a plant cell you see a structure external to the plasma membrane called the cell wall. In eukaryotic cells such as plant and animal cells the cytoplasm consists of three main components.

Vacuoles are membrane bound sacs within the cytoplasm of a cell that function in several different ways. They are the cytosol organelles and various. The sequence of bases in dna encodes the genetic information required to synthesize proteins. Plant cells are typically distinguished by their large water filled central vacuole chloroplasts and rigid cell walls that are made up of cellulose hemicellulose and pectin.

The cell wall is a rigid covering that protects the cell provides structural support and gives shape to the cell. In mature plant cells vacuoles tend to be very large and are extremely important in providing structural support as well as serving functions such as storage waste disposal protection and growth. Inside the cell is the cytoplasmic region that contains the genome dna ribosomes and various sorts of inclusions. Dna adduct the complex formed when a chemical forms a covalent bond with dna.

Unlike prokaryotic cells the dna in a plant cell is housed within a nucleus that is enveloped by a membrane. Some eukaryotic cells plant cells and fungal cells also have a cell wall. Eukaryotic cells are found in plants animals fungi and protists. In these cells the cytoplasm consists of all of the contents of the cell inside the plasma membrane.

In addition to having a nucleus plant cells also contain other membrane bound organelles tiny cellular structures that carry out specific functions necessary for normal cellular operation. They generally have a nucleus an organelle surrounded by a membrane called the nuclear envelope where dna is stored there are a few exceptions to this generalization such as human red blood cells which don t have a nucleus when mature.
