Scientists divide plants into two main groups depending on whether they reproduce by seeds or spores. Plants that reproduce by seeds Seed plants have special structures on them where male and ...
The flowers and fruit of flowering plants come and go as part of their life cycle. Some flowering plants don’t even have stems and leaves all the time. The fruit and vegetables we eat come from ...
A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes. Examples include quartz, feldspar minerals, calcite, sulfur ...
The life cycle of ferns is different from other land plants as both the gametophyte and the sporophyte phases are free living. This interactive illustrates the alternation of generations in ...

All living things depend on one another to live. Animals eat plants and/or animals to survive. Food webs describe the feeding connections between organisms in an ecosystem. The three main groups ...
Scientists currently consider that New Zealand has approximately 230 species of fern in about 50 different genera. They are widely distributed throughout the country, including around 42 species ...
Although earthworms are classified as animals, their bodies are quite different to animals that live above the ground. This video highlights some of the interesting physical characteristics ...
Matter is anything that occupies space and has mass. All physical objects are composed of matter, and an easily observed property of matter is its state or phase. The classical states of matter ...

Toxicity can be measured by the effect the substance has on an organism, a tissue or a cell. We know that individuals will respond differently to the same dose of a substance because of a number ...
Humans have many reasons to grow plants. We use them for food, for building materials, for pleasure and for many other purposes. A plant really just has one reason to grow – to reproduce and make ...
