Girth of the stem increases due to lateral meristematic tissues. They are found beneath the bark (called cork cambium) and in vascular bundles of dicot roots and stems (called vascular cambium) as thin layers. This increase in the diameter and girth of the plant is called secondary growth.

In vascular plants, phloem is the living tissue that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation.

Adipose tissue, body fat, or simply fat is a loose connective tissue composed mostly of adipocytes In addition to adipocytes, adipose tissue contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages.
Adipose tissue is derived from preadipocytes. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body. Far from being hormonally inert, adipose tissue has, in recent years, been recognized as a major endocrine organ, as it produces hormones such as leptin, estrogen, resistin, and the cytokine TNFa.
The two types of adipose tissue are white adipose tissue (WAT), which stores energy, and brown adipose tissue (BAT), which generates body heat. The formation of adipose tissue appears to be controlled in part by the adipose gene.

Euglena belong to the phylum Euglenozoa. Members of this phylum are unicellular organisms mostly found in freshwater, with a few found in saltwater. The all have a flagellum to use for movement and have chloroplasts, but can also feed as heterotrophs.

Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. Modern amphibians are all Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems

Antoine Lavoisier was a French scientist known as the ‘Father of modern chemistry’.
He gave chemistry the precision of a branch of science and the universal language.
It was Lavoisier’s experiment that paved the way for the law of conservation of mass.

Matter cannot be destroyed or created.
The only difference is in the form of the chemical reaction.

Lavoisier named sulfuric acid and zinc oxide.

Zinc phosphide is used as a rat poison is an inorganic compound that combines phosphorus with zinc. It is used in rodenticide baits. When an animal eats the bait, the acid in the animal’s stomach turns the zinc phosphide into phosphine.
. Phosphine is a very toxic gas.It’s lead to the death of that rodenticide.

Robert Hooke, an English scientist, discovered a honeycomb-like structure in a cork slice using a primitive compound microscope. He only saw cell walls as this was dead tissue. He coined the term “cell” for these individual compartments he saw.

The mitochondrion (plural mitochondria) is a double-membrane-bound organelle found in most eukaryotic organisms.
In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling, cellular differentiation, and cell death, as well as maintaining control of the cell cycle and cell growth.
Mitochondria are organelles found in the cells of most eukaryotes, such as animals, plants, and fungi, that are responsible for generating cellular energy.
They are surrounded by a double membrane system, with the inner membrane forming folds that extend into the interior of the organelle.
