Introduction to Biology

 

The study of biology incorporates everything imaginable that is related to the life on Earth – from the entire planet to tiny microscopic structures, biology covers it all. Studying living things, called organisms, takes us all around the world, from the most productive tropical rain forests to the hostile lands of Antarctica or the deepest oceanic basins.

Animals

A World of Animals

Mammals

Mammals are a group of warm-blooded vertebrate animals and include the largest animals on the planet. They are distinguished from other animals by having hair or fur and mammary glands for milk production in females.

Birds

Birds are a class of animals known as Aves and are distinguishable from other animals by having wings and feathers. Birds are currently the largest group of vertebrate land animals with more than 10,000 species found around the world.

Reptiles

Reptiles, class Reptilia, are a group of animals that include snakes, lizards, crocodiles, turtles and tuatara. They are an ancient group of cold-blooded, egg laying vertebrates with scales or scutes rather than fur or feathers.

Fish

Fish are a group of aquatic animals with skulls, gills and digitless limbs. Fish were the first vertebrate animals to evolve and there is now more than 30,000 species living on Earth, the highest diversity found in tropical coral reefs.

Invertebrates

An invertebrate is any animal without an internal backbone such as insects, shellfish, worms, and jellyfish. The diversity of invertebrates far outnumbers that of the vertebrate animals, making up roughly 95% of all animal species. 

Animals are the most advanced living things on the planet. They have evolved into a huge variety of shapes and sizes, adaptations and behaviors that makes studying animals a fascinating area of biology.

Plants

Angiosperms

 All plants that grow flowers and fruit belong to the group known as the angiosperms. They the most advanced, diverse and abundant group of plants in the world and include around 200,000 plant species.

Gymnosperms

Gymnosperms are a group of woody, vascular plants with seeds but without flowers or fruit. The seeds of gymnosperm plants sit exposed on cones rather than enclosed in a fruit as they are with angiosperm plants.

Ferns & Lycophytes

Ferns and lycophytes are two groups of vascular plants without wood, seeds or flowers. They include over 12,000 species from an ancient groups of plants that once dominated the forests in many parts of the world.

Non-vascular plants

The non-vascular plants include mosses, hornworts and liverworts and some algae. They are generally small plants limited in size by poor transport methods for water, gases and other compounds.

Plant Physiology

Plant physiology encompasses the study of plant form and function. As plants evolved to life on land they were required to evolve methods to extract CO², light and water from the atmosphere and soil.

Plants are essential to almost all life on Earth. By converting sun light and carbon dioxide into sugars, plants build the foundations for all land based ecosystems and the majority of aquatic ecosystems.

Environment

One World

 

The environment provides living things with everything that is necessary to survive such as nutrients in the soil, water and sunlight.

Micro

Discover the Microscopic World

 

The study of the microscopic world falls into two main categories, firstly the study of microscopic organisms, such as bacteria and phytoplankton, which exist in huge masses and make up as much as 90% of the world's living activity. 

The second branch of microscopic biology is the study of the structures and compounds that make an organism. Each organism contain one or many cells, and each cells is run by a series of chemical reactions that keep it alive.
