- They are the smallest membrane-bound organelles which comprise RNA and protein. They are the sites for protein synthesis, hence, also referred to as the protein factories of the cell.

It is the outermost, protective layer of a plant cell having a thickness of 20-80 nm. Cell walls are made up of carbohydrates such as cellulose, hemicellulose, and pectin and a complex organic polymer called lignin.
They are double membrane-bound organelles that have their own genetic material. Plastidsare mainly of three types: a) Chloroplasts: Found in the green parts of a plantand algae that contain the photosynthetic pigment, chlorophyll. b) Leucoplasts: Found in the non-photosynthetic tissues of plants. c) Chromoplasts: Colored plastics found in fruits an...
It is the large vesicle that make up almost 30 to 80% of the total plant cell volume. The central vacuoleis often the largest organelle in the cell that is filled with fluid, ions, enzymes, and other molecules. Apart from plants, they are also present in algae.
It is a thin, biological membrane having a thickness of 7.5-10 nm that separates the interior of the cell from the outside environment. The plasma membrane is selectively permeable in nature, which is mainly composed of lipids and proteins, with some carbohydrates attached to them.
It is a series of membranes within the cytoplasm that forms connections with the nucleus on one side and cell membrane on the other. It is of two types: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The surface of RER has ribosomesattached to it, while they are absent in SER.
Also known as Golgi body or Golgi complex, they are stacks of five to eight membrane-covered sacs called cisternae. The Golgi apparatus acts as the post office of the cell by packaging and transporting proteins from their source RER to their destination.The number of Golgi apparatus varies in cells according to their functions.
They are a network of long and thin protein fibers present in the cytoplasm of the cell having a diameter of 3-6 nm. Microfilamentsare composed of actin proteins that make them extremely strong and flexible.
They are fibrous hollow rods composed of proteins called tubulin. Microtubuleshave an outer diameter of 23-27 nm and an inner diameter of about 11-15 nm. They can grow to as long as 50 µm and thus are highly dynamic.
They are made up of two proteins forming a coiled-coil structure. Intermediate filaments have a diameter of 8-10 nm that are intermediate in size to microfilaments and microtubules. Microtubules, together with microfilaments and intermediate filaments, form the cytoskeletonof the cell.
It is a rod-shaped double membrane-bound organelle that contains its own DNA and ribosomes. Mitochondria are often called the ‘powerhouse of the cell‘, producing ATP that drives all cell-based metabolic activities.

Jun 11, 2004 · HEN1 encodes a protein that functions similarly to DICERLIKE1 (DCL1), a protein important for the production of miRNAs and small interfering RNAs (reviewed by Bartel and Bartel, 2003).
Sep 11, 2017 · The B function is provided by two MADS box genes, APETALA3 (AP3) and PISTILLATA (PI), while the C function is provided by the MADS box gene AGAMOUS (AG). The combinatorial action of the ABC proteins results in part from expression of their genes in discrete domains of the developing flower.
The tRNA carries amino acids to the ribosome, where the arrangement is made. Because protein synthesis is an essential function of all cells (including enzymes, hormones, antibodies, pigments, structural components, and surface receptors), there are ribosomes in practically every cell.
