How to teach cell in elementary school
Of course, it is the nucleolus. This has no membrane, it is a structure formed by DNA and other molecules responsible for the manufacture of proteins in the cytoplasm. In addition to RNA transcription, it also regulates the cell cycle, cell stress and aging.
To make it a little more understandable, during cell division chromatin compacts and gives rise to chromosomes, which are visible under the light microscope; these have a shape like the one you will see in the following image.
To get an image of the chromosomes, you would have to go to a specialized laboratory where they will take a sample of venous blood from your arm, although it can also be obtained from a sample of your bone marrow.
Actually, these studies are intended to detect abnormalities in the chromosomes and to diagnose genetic diseases, to find the cause of some congenital disorders. This study is not cheap.
Planning a lecture on the cell
Kinetics of L. (L) mexicana infection in neonatal BALB/c mice receiving dentritic cells from healthy adult mice (). It represents the positive control (n = 5) of infection with Leishmania and () represents the experimental group (n = 5) to which dendritic cells from healthy adult mice were transferred intraperitoneally (ip) 16 hours before infection with promastigotes (P < 0.05 from the third week).

Problem situations on cell
The epidermis is the outer layer of the skin. This tough, protective outer layer is thin in some areas and thick in others. The epidermis has layers of cells that are constantly shed and renewed. In these layers there are three special types of cells:
Beneath the epidermis is the dermis. Here are the blood vessels, nerve endings, sweat glands and hair follicles. The dermis nourishes the epidermis. In the dermis there are two types of fibers (collagen and elastin) that help the skin to stretch and stay firm.
The deepest layer of the skin is the subcutaneous tissue. It is made up of connective tissue, blood vessels and cells that store fat. This layer helps protect the body from bumps and other injuries, and helps maintain body temperature.
At the bottom of the follicle is the papilla, which is where hair growth actually occurs. The papillae contain an artery that nourishes the hair root. As the cells multiply and produce keratin to harden the structure, they are pushed out of the follicle and across the surface of the skin in the form of hair or vellus hair.
Evidence of learning about the cell
In this article we are going to tell you a little about how we make some of the pieces of DIY workshops. In this case, these are cells of animals and plants that we see in subjects such as Environmental Knowledge and that make up various tissues of organisms, it is functional and necessary to generate various processes essential for the existence of animals and plants.
To make these pieces we have chosen to make them with 3D printing, as it gives a very nice finish, but it could be done using other materials, for example, recycled materials, but we will see that in another article.
Part 2: Once we have all the pieces printed, we have painted them (although we have used filaments of different colors, some pieces we liked more with very specific colors). For this we have used Vallejo acrylic paint, which give very good results and have a wide range of colors, and then, we have varnished with polyurethane varnish also Vallejo to give more durability to the paint and resist the passage of time.
