The origins of life (1971)

The film is dedicated to this major mystery of life - the energy of the sun.

It explains how to light, heat, radiant power of the sun is converted into a living dead, creating the most amazing and bizarre creatures, plants, shapes - all organic nature in its rare diversity.

The device of the plant leaf.

The lower part of the leaf with holes are the stomata that suck carbon dioxide from the atmosphere.

The process of photosynthesis.

The chlorophyll molecule, having received a photon of sunlight, starts the process of photosynthesis.

As a result of photosynthesis, oxygen is released from the water molecule and enters the atmosphere.

The remaining components become organic matter.

Organic substances nourish all plant organs.

Solar energy converted into chemical energy accumulates in all parts of the plant.

The scheme of fertilization of plants.

When pollen gets on the pistil of a female plant, the pollen germinates, the shell stretches out and turns into a tube.

Two sperm cells are moving through the tube.

The tube penetrated into the lower part of the pistil - the ovary.

The sperm merged in pairs with the female cells of the plant.

By cell division, the embryo appears and nutrition for it.

The ovary turns into a fruit.
