The correct answer is Collenchyma.
The collenchyma cells are lengthened cells with uneven thick cell walls, which are responsible for structure and support. Their thick walls comprises of the compounds pectin and cellulose. These cells are generally found below the epidermis, or the outer layers of cells in leaf veins and in young stems.
These cells provide structural support, mainly in developing leaves and shoots. The strength of the tissue comes from these condensed cell walls and the longitudinal meshing of the cells.
True.An operon is a prokaryote. Its is a group of genes working together to make a specific protein.
These groups are arranged in order from most inclusive (most general) to least inclusive (most specific) is gnathostomes, osteichthyans, lobe-fins, tetrapods, amphibians.
<h3>What is
gnathostomes?</h3>
The jawed vertebrates are called gnathostomata. The phrase comes from the Greek words "jaw" and "mouth." Approximately 60,000 species make up the diversity of the gnathostome, which represents 99% of all vertebrates still alive today.
<h3>What is
osteichthyans?</h3>
A broad taxonomic group of fish called osteichthyes, also known as the "bony fish," has skeletons that are predominantly made of bone tissue.
<h3>What is
lobe-fins?</h3>
The taxon Sarcopterygii, also known as Crossopterygii, is made up of bony fishes noted for having lobe-finned fishes as its members.
<h3>What is
tetrapods?</h3>
Four-legged vertebrates that make up the superclass Tetrapoda are known as tetrapods, which derives from the Ancient Greek (tetra-) "four" and "foot." It consists of synapsids, dinosaurs, and extinct as well as living amphibians, reptiles, and dinosaur-related birds (including mammals).
