If talking of human body, largest cell is OVUM or egg cell owing to its diameter however nerve cells are the longest cell.
And all over the world the largest and longest cell are the NERVE CELLS Giant Squid and Colossal Squid.
If talking about plants… Caulerpa is a unique organism.

Which is the largest cell in world?
Biologists used the world’s largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.
Which is the longest cell in the human body?
The longest cells in the human body are neurons. Neurons or the nerve cells form the basic components of the nervous system. A typical neuron possesses a cell body called as soma, hair like structures called as dendrites and an axon.
Which is the longest cell in animals?
Of course, the longest animal cell is the nerve cell or neuron present in the nervous system comprising Brain, spinal cord and nerves. These cells have long body consisting of axons and dendrites .
Which is the largest and smallest cell in our body?
Granule Cell of the Cerebellum is the smallest cell of the human body it is approximately 4um to 4.5um in size. The largest cell in the human body is the female ovum or egg.
What is the largest cell in the male human body?
The longest cell is the nerve cell. The largest cell in the human body is female ovum. Smallest cell in the human body is male gametes, that is, sperm.
Which is the smallest cell in world?
Which is the smallest cell in the world? Mycoplasma genitalium, a parasitic bacterium which lives in the primate bladder, waste disposal organs, genital, and respiratory tracts, is thought to be the smallest known organism capable of independent growth and reproduction.
What is the shortest living cell in the human body?
would be the longest lived (e.g stem cells that form blood cells such as lymphocytes, red blood cells and platelets). Stem cells are found in many tissues including self-renewing ones such as the blood/bone marrow, gut epithelium and skin. Neurons are long lived and are generally non-mitotic.
What is the smallest cell in the female body?
“Ovum is the largest cell of the female and sperm is the smallest cell of the male. As far as longest cell is concerned, it is nerve cell.”
Why does a person become paralyzed?
Causes. Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson’s disease, ALS, botulism, spina bifida, multiple sclerosis, and Guillain–Barré syndrome.
Which is largest cell?
The largest cells found in nature are ostrich eggs. Before fertilization, the entire interior of the egg consists of a single cell, which can weigh up to 5 pounds. The largest single-celled organism is an animal called Syringammina fragilissima, which can grow to a width of 4 inches.
Which is the smallest cell in human body?
Which is the longest plant cell?
The longest cell in plant is fibre of Ramie.
Why is the egg larger than sperm?
Since it is so much bigger than sperm, the egg is the source of cytosol and organelles,particularly mitochondria, for the future zygote. Unlike sperm, the egg has not completed meiosis – it’s stuck in the Metaphase II stage of division.
What is the smallest organ in the human body?
What’s the smallest bone in the human body? Conveniently, 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 second smallest organ in the human body?
The pineal gland is considered to be the smallest organ in the human body.
What animal has the smallest sperm?
The largest, and smallest, sex cells on the planet. The 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.
Why ostrich egg is the largest cell?
The 1.5 kg ostrich egg contains the largest existing single cell currently known, though the extinct Aepyornis and some dinosaurs had larger eggs. The bee hummingbird produces the smallest known bird egg, which weighs half a gram.
Do bigger animals have bigger sperm?
Period. It is a freakish extreme, but as a general rule, scientists have long known that the smallest animals have the biggest sperm, and vice versa. In a study published Wednesday, researchers said not only sperm length, but also numbers, are determined by an animal’s size.
How many cells are in a sperm?
How many cells are in a human egg?
An egg, like a sperm, contains half the number of chromosomes as a normal cell, i.e. 23 each. So once an egg and sperm combine during fertilisation the resulting embryo will have the normal 46 chromosomes in total.
Do bigger animals have bigger cells?
The question of whether cells are bigger in larger mammals than in smaller ones — think of an elephant’s liver cell compared with a liver cell from a mouse — is usually answered by saying that larger mammals don’t typically have bigger cells, they just have more of them.
Can a paralyzed person walk again?
Paralyzed man walks again thanks to spinal implant. New electrical implants were able to assist subjects with spinal injuries in walking and regaining feeling in their limbs. If it is damaged, the neural signals can have trouble getting through, leaving a person paralyzed or otherwise disabled.
Can you cure paralysis?
Currently, there is no cure for paralysis itself. In certain cases, some or all muscle control and feeling returns on its own or after treatment of the cause for the paralysis.
Can a paralyzed man have a baby?
Most paralyzed men are able to have a reflex erection with physical stimulation unless the S2–S4 pathway is damaged. Spasticity is known to interfere with sexual activity in some people with SCI.
