Electron microscopic motifs of biological structures. In Photoshop lavishly colored. Large-format art calendar printed in high quality: special fluorescent colours, UV clearcoat finish. Manual wire-o-ring binding.
The picture shows a small part of a rice leaf. The crystal-like panels on the whole surface are from wax and protect the plant against water loss. Some stomatal pores, brown coloured, can be recognized in the lower picture area. They regulate the water household and CO2 exchange of the plant.
Apoptosis is the process of programmed cell death. In this process the cell shrinks and disintegrates into many single vesicles, which can be taken up by macrophages (white blood cells). Permanently, Apoptosis takes place in the body, because most cells only have a restricted life span.
Dinoflagellates are flagellate protozoans which are to be found both in salted and fresh water. Most species pursue photosynthesis. In the oceans there is repeated massive algal bloom that causes negative impacts to other organisms via production of neurotoxins and can lead to fish death
These louse flies infect bats. With the help of their claws, they can move well in the fur of the host and change the host without difficulty within the colonies. As an adaptation to the bats living close together in caves louse flies have lost their eyes and wings.
The image shows the skin of a larva of the Anopheles moscito with a fan-shaped hair. Anopheles mosquitoes lay their eggs in standing or slowly flowing waters. The larvae feed on microorganisms directly under the surface.
Enterococci are found in the gut of almost all vertebrates. These bacteria have a high tolerance to pH variations and the salinity of their environment. They can cause infections in the urinary tract, wound infections, and endocarditis.
The picture shows the struts within a femoral head. These struts are the spongy bone, which has a high stability at a low weight. This bone is weakened by osteoporosis (yellow zones). Misdirected osteoclasts have reduced the osseous tissue.
Ultrathin section through a white blood cell, a monocyte. These immune cells are able to absorb and remove foreign bodies. Clearly visible is the red-coloured nucleus, in blue the mitochondria and the endoplasmic reticulum (pink).
This mat made of hard and soft wood, i. e. beech and spruce, is used as filter material. The natural origin of the tissue can be recognized by the irregularly structured and partially perforated fibre.
The larvae of green lacewings feed predatory on aphids. They seize the aphids with their mandibles, transformed to big pliers and suck them.
This plastic foam is a further development of the styrofoam. It has an altered molecular structure that makes the material more stable and shock absorbing. This foam is mainly used as packaging material. You can see the inner walls of the foam.
The Physalis is also named cape gooseberry or groundcherry. In the picture a weathered husk can be seen. In the center of the pericarp was the red berry reminding one of a small tomato. Physalis is a genus of plants in the nightshade family.
