Which is biggest animal cell?
Caulerpa taxifolia is the largest animal cell.
it is an aquatic alga.
Largest animal cell is ostrich eggs measuring about 170*135 mm in diameter..
What is the longest nerve cell?
The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across).
What is inside Quark?
A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.
Which is the longest plant cell?
Fibres of Ramie are the longest plant cells with the length upto 21.65 inches long. It is elongated by intercalary growth and intrusive tip growth.
What is the smallest thing in the human body?
stapesConveniently, that would be the stapes. It is one of three tiny bones in the middle ear that convey sound from the outer ear to the inner ear. Collectively called the ossicles, these bones are individually known as the malleus, incus, and stapes.
What is the smallest thing we can see with our eyes?
The smallest object which an average human can see with the naked eye close up is one tenth of a millimetre diameter 0.1mm. This is the ability of being able to see what colour it is, whether it is dust, sand, or a tiny full stop.
Are humans 99.9 percent empty space?
Every human on planet Earth is made up of millions and millions of atoms which all are 99% empty space. If you were to remove all of the empty space contained in every atom in every person on planet earth and compress us all together, then the overall volume of our particles would be smaller than a sugar cube.
Is RBC the smallest cell in human body?
The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometres to 4.5 micrometres long. The RBC’s size also found roughly 5 micrometres. Most scientists suggest that sperm is the smallest cell in terms of volume.
What is inside a neutron?
A neutron contains two down quarks with charge −1⁄3 e and one up quark with charge +2⁄3 e. Like protons, the quarks of the neutron are held together by the strong force, mediated by gluons. The nuclear force results from secondary effects of the more fundamental strong force.
What’s the smallest thing in the world?
quarksProtons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
Which is the smallest animal cell?
Mycoplasma gallicepticumThe smallest cell is Mycoplasma gallicepticum. It is about 10 micrometer in size. The largest cells is an egg of ostrich.
Is nerve cell the longest cell in human body?
Neurons are the oldest and longest cells in the body! You have many of the same neurons for your whole life.
What’s the heaviest organ in the body?
liverThe largest solid internal organ is your liver. It weighs approximately 3–3.5 pounds or 1.36–1.59 kilograms and is about the size of a football.
Can an atom die?
Since an atom has a finite number of protons and neutrons, it will generally emit particles until it gets to a point where its half-life is so long, it is effectively stable. … It undergoes something known as “alpha decay,” and it’s half-life is over a billion times longer than the current estimated age of the universe.
Which is the smallest cell?
spermThe sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable. Most species have two gametes, which we term male and female.
