Deep in the forest, under the giant trees, lie the ancient pteridophytes, the ferns. They are not conspicuous or dominating, seldom reaching more than a meter or so high, with the exception of the tree ferns. They never flower and seldom are seen beyond the...

A "Phylogenetic relationship" can be defined as being a reference to a timeline in the past that a species shared common ancestors.Our understanding about phylogenetic relationships hinges on the patterns we see within evolutionary changes occurring along the passage of time. Darwin called it...
How to become a botanist
By: Chu Chin Kwok
By the time you are in High School, you probably have some idea of what you want to study in college, that is - if you intend to obtain more than a High School Diploma. For students who are not really mathematically inclined, life sciences...

The dark brooding spruce trees of the taiga, windswept cypress trees on the California coast, giant Norfolk pines dotting the skylines of beach towns along the Australian coast: what do they all have in common? They are gymnosperms, cone bearing plants which never flower and...
By: M E Skeel
The most important gymnosperms are the conifers but even the rare species are valuable for what they can tell us about plant evolution and also as important members of their respective ecosystems, contributing food, shelter and clean air to the animals that live there. The...

When we think of competition, we usually think of animals competing for food, territories or mates. But plants compete too. It's true that most plants can make their own food but they need sunlight to do so. Although sunlight is in great abundance and most...
By: M E Skeel
There are basically two types of plants that live on land: those with vascular tissues (xylem and phloem for carrying water and nutrients through the plant's body) and those that do not. The first plants to conquer the land were nonvascular. These are the mosses...
Types of epiphytes described
By: James Johnson
Epiphytes, how many types are there? No one really knows. In one research project, they found over 2100 species in just 500 square meter, about the size of a very small front yard! And epiphytes are not just in the tropics, but every where! There...

The major difference between a monocotyledon (monocot) and a dicotyledon (dicot) is that a dicot has two cotyledons and a monocot one. The cotyledon is the seed endosperm contained within the testa (seed coat). If you take the large seed of a dicot like a...
How epiphytes contribute to forest diversity
By: James Johnson
Biodiversity is the the variety of live found in different environments and ecosystems around the world. Any living organism, plant animal or even microorganism increases or contributes to the biodiversity. Epiphytes greatly increase the biodiversity of rainforest.An epiphyte is any plant that does not...
