Plant Cell Parts
Plant cells are constituted from the different parts. These parts play a significant role in the proper functioning of the cell. For your ready information the planr cell parts are like:
The cell membrane surrounds the cytoplasm of a cell and physically separates the intracellular components from the extra-cellular environment, thereby serving a function similar to that of skin.
A cell wall is a fairly rigid layer surrounding a cell, located external to the cell membrane, which provides the cell with structural support, protection, and acts as a filtering mechanism. The cell wall also prevents over-expansion when water enters the cell.
Plasmodesmata are microscopic channels of plants traversing the cell walls of plant cells and enabling transport and communication between them.
Vacuoles are found in the cytoplasm of most plant cells. Vacuoles are membrane-bound compartments within some eukaryotic cells that can serve a variety of secretory, excretory, and storage functions.
A vacuole is surrounded by a membrane called the tonoplast.
Plastids are responsible for photosynthesis, storage of products like starch and for the synthesis of many classes of molecules such as fatty acids and terpenes which are needed as cellular building blocks and/or for the function of the plant.
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb light and use it in conjunction with water and carbon dioxide to produce sugars, the raw material for energy and biomass production in all green plants.
Leucoplasts are a category of plastid and as such are organelles found in plant cells. They are non-pigmented, in contrast to other plastids such as the chloroplast.
Chromoplasts are plastids responsible for pigment synthesis and storage. They, like all other plastids are organelles found in specific photosynthetic eukaryotic species. Chloroplasts in the traditional sense, are found in colored organs of plants such as fruit and floral petals, to which they give their distinctive colors.
Golgi complex is an organelle found in most eukaryotic cells. The primary function of the Golgi apparatus is to process and package the macromolecules such as proteins and lipids that are synthesized by the cell.
Ribosomes are complexes of RNA and protein that are found in all cells. The function of ribosomes is the assembly of proteins, in a process called translation.
These structures are responsible for several specialized functions: Protein translation, folding, and transport of proteins to be used in the cell membrane or to be secreted from the cell; sequestration of calcium; and production and storage of glycogen, steroids, and other macromolecules.
it is a membrane-enclosed organelle that is found in cells. Mitochondria are sometimes described as “cellular power plants,”.
are one of the components of the cytoskeleton. They have diameter of ~ 24 nm and length varying from several micrometers to possibly millimeters in axons of nerve cells.
Microfilaments are the thinnest filaments of the cytoskeleton found in the cytoplasm of all eukaryotic cells
Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
A microbody is a cytoplasmic organelle of a more or less globular shape that comprises degradative enzymes bound within a single membrane.
Cytoplasm is a gelatinous, semi-transparent fluid that fills most cells.
It contains most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes.
The nuclear envelope consists of two cellular membranes, an inner and an outer membrane, arranged parallel to one another and separated by 10 to 50 nanometers (nm).
DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms.
Chromatin is the complex of DNA and protein that makes up chromosomes.
RNA plays several important roles in the processes of translating genetic information from DNA into proteins.
hi my name is cole wisby and im learning about cells and how our body is made of millions of cells. i did a project today on the cell model. i made a cake and i think i missed some things and i turn it in tomorrow. well i like the web site and ill check it out more often.
and we are also studying about the cells of plants and animals and we have to report tommorow 😀
Hey you really really help me for my test.. THANK YOU …..
=) this is jamesh a sophomore student…
Hello. I’m Alexis (Lexi) Rinard. I am learning about plant cells. I have to do a paper on them, and I was absent the WHOLE time my class was learning about them. I was on vacation, by the way. So I have no idea what all these words look like….. So could you tell me? Please! It would help alot.
