Is it true all cell have cell walls?
Only plant cells have walls
Why don't they build walls around cities anymore?
Flight and advanced firearms have essentially made the value of walls as a defensive measure useless.
What is the significance of the wall of red earth in Things Fall Apart?
Red earth is used to build walls. Red earth cleans the walls and makes them shine.

Microscopic unicellular marine or freshwater colonial alga?
The microscopic unicellular marine or freshwater colonial algae is a diatom. The cell walls are impregnated with silica. Plankton is primarily a microscopic organism that occupy the upper water layers in fresh water and ecosystems.
Microscopic or freshwater unicellular alga having cell walls impregnated with silica?
The organism you're referring to is called a diatom. Diatoms are a type of algae that have intricate cell walls made up of silica, which gives them a unique and intricate appearance. They are typically found in freshwater environments and play an important role in aquatic ecosystems.
What phyla of organism have silica glass walls and are bioluminescent?
Actinopoda
What do the cell walls of diatoms contain?
Diatom cell walls are composed of silicon dioxide.
What organism has silica walls?
class chrysophyta
What are found in bacteria?
Bacteria are single-celled, and they have cell walls. They do not have nuclei. They are also microscopic.
How many capillares in your human body?
capillaries are microscopic blood vessel that have single-celled walls.
How do nutrients in digestive system reach the blood stream?
Through millions of microscopic villosity placed on the walls of the small intestine.
What makes up a plant cell wall?
Composition of Cell Wall:The major Carbohydrates making up the primary (budding) plant cell wall are cellulose, hemicellulose and pectin. The cellulose microfibrils are linked through hemicellulosic chains to form the cellulose-hemicellulose web, which is fixed in the pectin matrix. The most common hemicellulose in the primary cell wall is xyloglucan. In grass cell walls, xyloglucan and pectin are sometimes partially replaced by glucuronarabinoxylan.The outer part of the primary cell wall of the plant epidermis is usually impregnated with cutin and wax, forming a permeability barrier known as the plant cuticle.Secondary cell walls contain a wide range of other compounds that modify their mechanical properties and permeability. The major polymers that make up wood (largely secondary cell walls) include cellulose (35 to 50%), xylan (20 to 35%) and lignin (10 to 25%). The walls of cork cells in the bark of trees are impregnated with suberin, and suberin also forms the permeability barrier in primary roots known as the Casparian strip. Secondary walls - especially in grasses - may also contain microscopic silica crystals, which may strengthen the wall. These silica crystals also ensure the survival of plant by saving them from getting grazed by herbivores.All these compounds working in coordination make the cell wall unbreakable.Cell Walls in Fungi:Fungal cell walls are made of chitin, the same material from which exoskeletons of insects are made, it is a polymer of glucosamine.Cell Walls in Diatoms:Diatomic cell walls are composed of Silicic Acid which is a compound of silicon, oxygen and hydrogen.Bacterial Cell Walls:In Eubacteria, cell walls are of peptidoglycan. In archaeobacteria, A variety of compounds make up cell wall for example Glycoproteins, Psuedopeptidoglycan and Polysaccharides.Check out the related links to see microscopic structure of Cell Wall.
Is reflection of light from smooth walls of our house regular or not?
It's not regular. If it were, the walls would be mirrors. Very few surfaces are actually smooth on the microscopic level, so most scatter light fairly randomly.
What makes the inside of a horsetail scratchy?
It's the silica crystals that make horsetail fern (Equisetum hyemale) a scratchy tool.Specifically, the plant forms silica crystals on the cell walls of its stems and branches. The crystals form in response to the drying of the plant's parts. It is the persistence of these crystals in the branches and stems that make the plant a scouring tool, in many places and throughout many time periods.
What is Si02?
The chemical compound silicon dioxide, also known as silica or silox (from the Latin "silex"), is an oxide of silicon, chemical formula SiO2, and has been known for its hardness since the 9th century[1]. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. It is a principal component of most types of glass and substances such as concrete. Silica is the most abundant mineral in the earth's crust.
