Monosaccharides
- Carbohydrate that cannot be hydrolyzed further to give simpler unit of polyhydroxy aldehyde or ketone is called a monosaccharide.
- About 20 monosaccharides are known to occur in nature.
1. Glucose: Glucose molecules can be broken down by glycolysis in the process of cellular respiration. Glucose can be connected in long strings of monosaccharides to form polysaccharides. In plants, this thing is produced as cellulose. In plants, each cell is surrounded by cellulose that helps plants stand tall and turgid.
2. Fructose: Fructose belongs to the ketose group. Differently shaped monosaccharides break down the specific enzyme. If fructose, combines with other monosaccharides then they form oligosaccharides. Sucrose has a fructose molecule joined with a glucose molecule with the help of a glycosidic bond.
3. Galactose: Galactose is produced by mammals in the form of milk. Lactose holds a lot of energy in its bonds and for breaking down the bonds apart, specific enzymes are developed by off springs of mammals.

- In diatoms the cell walls form two thin overlapping shells embedded with silica.
- diatoms have left behind large amount of cell wall deposits in their habitat, which accumulated over billions of years is referred to as ‘diatomaceous earth’ .

A saprophyte or saprotroph is an organism which gets its energy from dead and decaying organic matter. This may be decaying pieces of plants or animals. This means that saprophytes are heterotrophs. They are consumers in the food chain. ... Some fungi are parasites on living organisms, but most are saprophytes. Mushrooms contain no chlorophyll and most are considered saprophytes. That is, they obtain their nutrition from metabolizing non living organic matter. This means they break down and "eat" dead plants, like your compost pile does.

All annelids except leeches also have chitonous hair-like structures, called setae, projecting from their cuticle. Sometimes the setae are located on paddle-like appendages called parapodia. Annelids are schizocoelous and with a large and well-developed true coelom (i.e., one that is lined with mesoderm). The basic features of locomotion in annelids are most easily observed in the earthworm because it lacks appendages and parapodia. Movement involves extending the body, anchoring it to a surface with setae, and contracting body muscles. ... The setae are retracted during the circular contraction period.

Consciousness is the state of being aware of surrounding. It is defined by the ability of the organism to respond to the stimulus which is known as irritability. If an organism is able to respond to stimuli, that means it is aware. As irritability is defining the property of life, so consciousness can be considered as defining property of a living organism.

(i) Phylum: The phylum is second highest unit of classification after Kingdom. It includes one or more related classes of animals. In plants, instead of phylum, the term ‘division’ is used.
(ii) Class: The class is a taxonomic group consisting of one or more related orders. For example, the class, Mammalia, includes many orders like Primata (Man), Carnivora (tiger) etc.
(iii) Family :Family is a taxonomic group containing one or more related genera, eg., Family hominidae contains apes, monkeys and man. In plants, families are categorized on the basis of vegetative and reproductive features.
(iv) Order : Order is a taxonomic group containing one or more families. For example, the order, carnivora, includes many families.
(v) Genus: Genus is a taxonomic group including closely related species. For example, the genus, Solanum, includes many species such as nigrum, melongena, tuberosum, etc.

The radula is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the oesophagus. The radula is the toothed chitinous ribbon in the mouth of most molluscs. It can be compared with the tongue of human beings but, unlike our tongue, it is used for cutting and chewing food before it enters the esophagus. The radula is present in all molluscs except bivalves, and only in molluscs.

Balanoglossus is a deuterostome, and resembles the Ascidians or sea squirts, in that it possesses branchial openings, or "gill slits". It has notochord in the upper part of the body and has no nerve chord. It does have a stomochord, however, which is gut chord within the collar. Balanoglossus is an ocean-dwelling acorn worm (Enteropneusta) genus of great zoological interest because, being a Hemichordate, it is an "evolutionary link" between invertebrates and vertebrates. ... Hyman (1959), however, placed them near Echinodermata and gave Hemichordata a status of an independent phylum.
