Susiję elementai

Animal and plant cells, cellular organelles

Eukaryotic cells contain a number of organelles.

Chlorophyll

Chlorophyll is a photosensitive green pigment found in plants; it absorbs light energy, thus plays a vital role in photosynthesis.

Greenhouse effect

Human activity increases the greenhouse effect and leads to global warming.

Oxygen cycle

The oxygen cycle describes the movement of oxygen within its three main reservoirs.

Enzymes

Enzymes are protein molecules catalysing biochemical reactions. Their activity can be regulated.

Oro užterštumas

Ši animacija rodo pagrindinius oro taršos šaltinius: žemės ūkio, pramonės ir miesto oro tarša.

Transport processes

This animation explains active and passive transport processes occurring through cell membranes

ADP, ATP

ATP is the main source of energy for cells.

Amoeba proteus

Widespread heterotrophic unicellular organisms with constantly changing shapes

Carbon cycle

Carbon is bound in organic substances during photosynthesis, while during breathing, it is released into the atmosphere.

Deforestation

Deforestation has a negative impact on the environment.

Flower

The animations demonstrates the structure of a typical flower.

Niche

In ecology, a niche is a term describing the way of life of a species.

Oxygen (O₂) (intermediate)

A colourless, odourless gas, an important component of the atmosphere, indispensable to sustain terrestrial life.

Seeds and germination

Dicotyledons have two embryonic leaves (cotyledons), while monototyledons have only one.

Surface tension

Surface tension is the property of a liquid that allows it to obtain the smallest surface area possible.

The anatomy of leaves

This animation presents the main types of leaves and the differences between monocot and dicot leaves.

The Sun

The diameter of the Sun is about 109 times that of the Earth. Most of its mass consists of hydrogen.

Vegetative plant organs

These organs are vital for the survival and development of plants.

Comparison of monocots and dicots

The two groups of angiosperms are monocots and dicots.

Euglena viridis

Unicellular eukaryotes living in freshwaters, capable of feeding autotrophically and heterotrophically.
