An example of a specialised animal cell could be of a nerve cell. The nerve cell contains axons of motor and sensory neurons‚ which are in bundles of fascicles. They are surrounded by connective tissue which is the sheath of perineurium which ensures that the cells do not get damaged. This lso helps do that the function of the cell is carried out correctly (Nerve Anatomy or Structure (Expanded View)‚ 2017). The function of a nerve cell is to emit impulses through electrical signals fromt the brain

Explain how the advance in technology allowed the progressive accumulation of knowledge and understanding of the cell theory The technological advancements‚ in the scientific field‚ have opened opportunities for scientists to accumulate knowledge and understanding of the cell theory and have thus provided justification to the living organisms that exist. Notably‚ prior to the proposal of the cell theory‚ limited knowledge and understanding of what humans comprised of was evident and thus the theory of

Stem cells -are biological cells found in all multi cellularorganisms‚ that can divide (throughmitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals‚ there are two broad types of stem cells: embryonic stem cells‚ which are isolated from the inner cell mass of blastocysts‚ and adult stem cells‚ which are found in various tissues. In adult organisms‚ stem cells and progenitor cells act as a repair system for the body‚ replenishing

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical

Using a microscope and slideshow and based on readings in the lab the following are answers to questions asked in the experiment. Based on the data gathered from observation differences in normal cells and cancerous ones have revealed themselves. Most

- The major functions of the cell is concentrated at the outer edges of the retina and are used in peripheral vision. On average‚ there are about 125 million rod cells in the human retina. Rod cells are almost entirely responsible for night vision. Rod cells do not process fine details or color differences‚ but are highly sensitive to light. A single flash of light is all that is require to produce a response from a rod cell. Rod cells function as specialized neurons that convert visual stimuli in
