- White blood cells. Neutrophils. Eosinophils. Basophils. Lymphocytes.
- Nerve cells.
- Neuroglial cells.
- Muscle cells. Skeletal muscle cells. Cardiac muscle cells. Smooth muscle cells.

What are the 5 main cells?
There are hundreds of types of cells, but the following are the 11 most common.
- Stem Cells. Pluripotent stem cell.
- Bone Cells. Colored scanning electron micrograph (SEM) of a freeze-fractured osteocyte (purple) surrounded by bone (gray).
- Blood Cells.
- Muscle Cells.
- Fat Cells.
- Skin Cells.
- Nerve Cells.
- Endothelial Cells.
What kind of cells are found in humans?
There are three types of blood cells: red blood cells, white blood cells, and platelets. Red blood cells (RBCs) are by far the most abundant type of cell in the human body, accounting for over 80 percent of all cells. Adult humans have somewhere around 25 trillion RBCs in their body, on average.
How many cells are there in a human body?
15 trillion cells
Which is biggest part of human body?
The largest internal organ (by mass) is the liver, with an average of 1.6 kilograms (3.5 pounds). The largest external organ, which is also the largest organ in general, is the skin. The longest muscle is the sartorius muscle in the thigh.
Which is the longest plant cell?
Why do cells stay small?
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. Cells are small so they can have an efficient surface area to volume ratio.
Which cell does not have nucleus?
Which cell can change its shape?
White blood cells
What can change its shape?
When a force acts on an object, the object may change shape by bending, stretching or compressing – or a combination of all three shape changes. Pull an object’s ends apart, eg when a rubber band is stretched. Push an object’s ends together, eg when an empty drinks can is squashed.
Does egg cell change its shape?
Answer Expert Verified →They can change their shape and show amoeboid type of movement . → They secrete enzymes which can engulf foreign pathogen and destroy them.
Why are sperm smaller than eggs?
In addition, egg contains almost all organelles, materials, and nutritions for zygote growth. However, a sperm only contains haploid chromosome and certain mitochondria for movement. This is the second reason why egg is larger than sperm.
Why are eggs so much larger than sperm?
Egg cells are considerably larger than sperm cells because they carry the cytoplasm and organelles necessary for cell division and growth to begin, while sperm cells are basically a cell nucleus and a tail.
Which of the following is the longest cell in human body?
Neurons or nerve cells can be up to 3 feet long. A typical neuron has a cell morphology called soma, hair-like structures called dendrites and an axon. Neurons are specialized in conveying knowledge throughout the body. The sensory neurons, motor neurons, and interneurons are three types of neurons.
What is the largest 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).
Where is the longest neuron in our body?
The longest neuron in the human body extends from the lumbar and sacral plexuses in the lower area of the spinal cord to the toes.
Is the powerhouse of the cell?
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
