A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue creates protective boundari...
This chapter presents the structure and function of the endocrine cell types of the islets. The islet cells are apparently interposed between and around the network of capillaries. Three cell types in the human islet can be identified with electron microscopy based upon ultrastructural differences in...
This allows it to provide structure and support to the plant. What is the main function of collenchyma cell? The main function of collenchyma cells is to provide structure and support for the growing parts of the plant. Collenchyma cells are more flexible than sclerenchyma but still provide ...
In turn, there are three types of white blood cells—lymphocytes, monocytes, and granulocytes—and three main types of granulocytes (neutrophils, eosinophils, and basophils). These cells all come from thebone marrowwhere they develop asstem cells, followed by their maturation into one of the thre...
The main function of the nucleus is to store DNA. DNA is the genetic material for the cell and holds all the information about the cells structure and function. It can be used during DNA replication which is required for cell division and during transcription, which makes the mRNA ...
These cells help in performing a secretory function. Depending on the location, structure, and functions, parenchyma can be divided into the following categories- Parenchyma Tissue Diagram To better understand the anatomy of Parenchyma, referring to a neat labeled Parenchyma Tissue Diagram is crucial...
Describe the structure and function of lymphocyte cells. Describe the function, characteristics, and location of epithelial cells. (a) Define Kupffer cells. (b) What is its function? Describe the function of type II alveolar cells. What is the function of cell division?
Recommended video: Cells and tissues [24:29] Overview of the main cellular components and tissues. Multipolar neuron Neuron multipolare 1/3 Synonyms: none There are over 200 different cell types in the human body. Each type of cells is specialised to carry out a particular function, ...
Other cells found in the skin include melanocytes, Merkel cells, and Langerhans cells. What is the structure and function of skin cells? The majority of skin is made of specialized squamous epithelial cells called keratinocytes. On the skin's surface, these cells are flattened and surrounded by...
