Is a virus a cell?
Because they can’t reproduce by themselves (without a host), viruses are not considered living. Nor do viruses have cells: they’re very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein.

Which is the longest animal cell?
Complete answer: Neuron also known as a nerve cell is a cell that is the longest cell of animals which has the capability to get excited by electrical or chemical impulse.
Is egg a cell?
The eggs of most animals are giant single cells, containing stockpiles of all the materials needed for initial development of the embryo through to the stage at which the new individual can begin feeding. Before the feeding stage, the giant cell cleaves into many smaller cells, but no net growth occurs.

The femur bone is the longest and strongest bone in the body. Located in the thigh, it spans the hip and knee joints and helps maintain upright posture by supporting the skeleton.
What is the smallest cell in the female body?

Which is weakest bone in human body?
The lacrimal bone is perhaps the most fragile bone of the face and one of the smallest bones in the body. Spanning between the middle of each eye socket, each lacrimal is thin and scalelike and serves as support for the eye. The pair of lacrimal bones are two of the fourteen facial bones.
What is the hardest bone to heal?
Treatments ranging from casting to surgery can be required. Unfortunately, the scaphoid bone has a track record of being the slowest or one of hardest bones to heal.

Which is the largest known cell?
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.
Who 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.
