Pinocytosis and Phagocytosis in Amoeba proteus

The film describes organization, form change and movement behavior of the amoeba cell. With specific protein or ionic solutions the pinocytosis activity can be increased. Channel and endosome formation can be observed. In lightmicroscopic shots and scanning electron microscope images the process of phagocytosis is shown. Prey organisms are Tetrahymena, ciliated unicellular organisms.

Pinozytose und Phagozytose bei Amoeba proteus

Der Film beschreibt Organisation, Formwandel und Bewegungsverhalten der Amöbenzelle. Eine ständige Pinozytose - die Aufnahme von Flüssigkeit mit darin gelösten und suspendierten Stoffen - ist am physiologischen Hinterende zu beobachten. Die Pinozytoseaktivität wird durch Zugabe bestimmter Protein- oder Ionenlösungen gesteigert, so dass die Kanalbildung und Abschnürung von Endosomen verfolgt werden kann. Die Phagozytose wird am Beispiel einzelliger Ciliaten der Gattung Tetrahymena gezeigt. Rasterelektronenmikroskopische Bilder vermitteln eine räumliche Vorstellung von der Amöbe bei Fortbewegung, Pinozytose und Phagozytose.

Yellow Loosestrife and Hair-legged Mining Bees (Lysimachia and Macropis)

Close interrelations between plants and animals have developed during evolution. One form of symbiosis is common in South America and Africa and is extremely fascinating: some flowering plants don't offer nectar or pollen, but a fatty oil. These flowers are called "oil flowers". This interrelation is hardly known in Europe although it occurs between bees (Macropis) and their host plant, the Yellow loosestrife (Lysimachia). The film was shot in their natural habitat at the banks of the Rhine backwaters. By means of macrography and slow-motion all phases of the bees' complex collecting behaviour are documented, including their nests. The flower structure is explained in detail. The film exemplarily introduces the basic mechanisms of a plant-animal interaction and the close connection between form and function in an ecosystem.

Malpighiaceae and their Pollinators

Close interrelations between plants and animals have developed during evolution. In Brazil one can find an extremely fascinating symbiosis: some flowering plants don't offer nectar or pollen, but a fatty oil. These flowers are called "oil flowers". The film shows the tight link between bees (Centridini) and their host plants (Malpighiaceae) in their natural habitat. By means of macrography and slow-motion all phases of the bees' complex collecting behaviour are documented, including microscopic shots of the bees' legs and their larvae. The flower structure is explained in detail. The film exemplarily introduces the basic mechanisms of a plant-animal interaction and the close connection between form and function in an ecosystem.

Pollination of Angelonia hirta (Scrophulariaceae)

Close interrelations between plants and animals have developed during evolution. In the garden and pastureland of Northeast Brazil one can study a fascinating symbiosis: some flowering plants don't offer nectar or pollen, but a fatty oil. They are called "oil flowers". The film documents the close interdependence between the bees (Centris) and plants (Scrophulariaceae) in their natural habitat. By means of macrography and slow-motion all phases of the bees' complex collecting behaviour are documented, including microscopic shots of the bees' legs. The flower structure is explained in detail. The film exemplarily introduces the basic mechanisms of a plant-animal interaction and the close connection between form and function in an ecosystem.

Everyday Tales (Bhilai, Chattisghar, India)

Life has changed a lot in Bhilai after the Steel Plant has been started. A grandfather explains to his grandson how the situation arose between industrialization and traditional agricultural life. The traditional joint family feels the differences between the common every day life (village, market place, and fieldwork) and the so-called developments of industrialization like jobs and regular income or higher education for children. Traditionally the people were paddy growers, like the grandfather. They had to give up their land for the Bhilai Steel Plant. All village people were afraid of what would come in the future. Many took the offered jobs. As a member of the local panchayat he tried to organize and support paddy growing. Now he combines both - industrial job and traditional agriculture - successfully and well-respected. But the question still remains.

All Things Bright and Beautiful

Raghvendra Chand Singh and Tejendra Tamraker travel to Germany for the first time in their lives. They visit a farm near Göttingen to explore modern-day dairy-farming. They capture the daily routines of their hosts on camera, trying to understand the latter's attitude towards their livestock. Being from India they are used to quite different notions of how one should think of and deal with cows.

Gilbweiderich und Schenkelbiene

Zwischen Pflanze und Tier haben sich im Verlauf der Evolution enge Wechselbeziehungen entwickelt. Eine Symbiose kommt gehäuft in Südamerika und Afrika vor und ist besonders faszinierend: Bei dieser bieten Blütenpflanzen den Bienen nicht - wie gewöhnlich - Nektar oder Pollen an, sondern ein fettes Öl. Man nennt sie deshalb "Ölblumen". Diese Wechselbeziehung ist in Europa kaum bekannt, obwohl sie auch hier vorkommt: zwischen Bienen der Gattung Macropis und ihrer Wirtspflanze, dem Gilbweiderich (Lysimachia vulgaris). Die Aufnahmen entstanden an den Ufern der Altarme des Rheins in der natürlichen Umgebung beider Partner. Mittels Spezialtechnik (Makro- und Zeitdehneraufnahmen) werden alle Phasen des komplexen Sammelverhaltens der Bienen sichtbar gemacht; Aufnahmen der Bodennester ergänzen das Material. Der Blütenaufbau wird detailliert vorgestellt. Damit vermittelt der Film beispielhaft die Grundmechanismen von Pflanze-Tier-Interaktionen und die enge Verknüpfung von Form und Funktion in einem Ökosystem.

Malpighiaceen und ihre Bestäuber

Zwischen Pflanze und Tier haben sich im Verlauf der Evolution enge Wechselbeziehungen entwickelt. In einem Naturreservat in Brasilien läßt sich eine besonders faszinierende Symbiose beobachten: Bei dieser bieten Blütenpflanzen den Bienen nicht - wie gewöhnlich - Nektar oder Pollen an, sondern ein fettes Öl. Man nennt sie deshalb "Ölblumen". Der Film zeigt, wie eng sich Bienen (solitär lebende Centridini) und Pflanzen (Vertreter der Malpighiaceen) ergänzen. Die Aufnahmen entstanden in einer Forschungsstation in der natürlichen Umgebung beider Partner. Mittels Spezialtechnik (Makro- und Zeitdehneraufnahmen) werden alle Phasen des komplexen Sammelverhaltens der Bienen sichtbar gemacht; Rasteraufnahmen der Bienenbeine und Aufnahmen der Larvenbrut ergänzen das Material. Der Blütenaufbau wird detailliert vorgestellt. Damit vermittelt der Film beispielhaft die Grundmechanismen von Pflanze-Tier-Interaktionen und die enge Verknüpfung von Form und Funktion in einem Ökosystem.

Bestäubung von Angelonia hirta (Scrophulariaceae)

Zwischen Pflanze und Tier haben sich im Verlauf der Evolution enge Wechselbeziehungen entwickelt. In der Garten- oder Weidelandschaft Nordost-Brasiliens läßt sich eine besonders faszinierende Symbiose beobachten: Bei dieser bieten Blütenpflanzen den Bienen nicht - wie gewöhnlich - Nektar oder Pollen an, sondern ein fettes Öl. Man nennt sie deshalb "Ölblumen". Der Film zeigt, wie eng sich beide Partner - Bienen der Gattung Centris und Pflanzen der Art Angelonia hirta - ergänzen. Die Aufnahmen entstanden in der natürlichen Umgebung beider Partner. Mittels Spezialtechnik (Makro- und Zeitdehneraufnahmen) werden alle Phasen des komplexen Sammelverhaltens der Bienen sichtbar gemacht; Rasteraufnahmen der Bienenbeine ergänzen die Bewegtbilder. Der Blütenaufbau wird detailliert vorgestellt. Damit vermittelt der Film beispielhaft die Grundmechanismen von Pflanze-Tier-Interaktionen und die enge Verknüpfung von Form und Funktion in einem Ökosystem.
