Leaving Cert Biology Bundle

Biochemistry is the chemistry of cells - or, put more plainly, how cells function. A cell is constantly being run by different chemical reactions inside it - the two main ones we will study are photosynthesis and respiration. These chemical reactions are driven by two types of  big molecules inside the cell - energy carriers and enzymes. Once we understand how cells work, naturally, we can manipulate them in industry to produce food, drink and medicine. In this lesson we will cover Higher Level Leaving Cert Biology Biochemistry. This lesson will cover:

• Metabolism
• ATP
• Enzymes
• Photosynthesis
• Respiration
• Biotechnology
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of Biochemistry!

The immune system is our body's natural defense against pathogens - bacteria, protists, fungi and viruses which cause disease. There are two parts to it - the innate and the adaptive immune systems. The innate immune system is a general defense against all pathogens, whereas the adaptive immune system involves a process where different types of white blood cells recognise and kill specific pathogens. Only once we understand how the immune system works, can we begin to understand what the different blood groups are and how people can become immune to certain pathogens. In this lesson we will cover Higher Level Leaving Cert Biology Blood and the Immune System. This lesson will cover:

• The Composition of Blood
• The Immune System
• Anitgens, Antibodies and Lymphocytes
• Blood Groups
• Viruses
• Immunity
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of Blood and the Immune System!

Ecology is the study of living organisms, the environment in which they live and the relationships between them. It's first important to understand how the ecosystem works, how energy moves from one level of the food chain to the next and how nutrients are recycled. Then we can look at how organisms interact with each other and how populations rise and fall. In this lesson we will cover Higher Level Leaving Cert Biology Ecology. This lesson will cover:

• The Ecosystem
• Nutrition and Energy
• The Carbon Cycle
• The Nitrogen Cycle
• Biotic Interactions
• Population Growth
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of Ecology!

There are 22 practical experiments on the leaving cert course. This lesson will first focus on the scientific method and how and why experiments are done. It will then cover nine key experiments - food tests (1 experiment), enzyme experiments (4 experiments) and the study of an ecosystem (4 experiments). The experiments are based off the theoretical course content and for these nine, it helps to have a good understanding of the cell, biochemistry and ecology. In this lesson we will cover Higher Level Leaving Cert Biology Experiments. This lesson will cover:

• The Scientific Method
• Food Tests
• Enzyme Experiments
• Study of an Ecosystem
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of Experiments!

Evolution is how species slowly change over time and in the middle of the 19th century, biology was transformed when two English naturalists, Charles Darwin and Alfred Russel Wallace, independently worked out just how evolution works. Around the same time, a Czechoslovakian monk, Gregor Mendel, began to work out the laws of inheritance - how traits are passed on from one generation to the next. Building on what Mendel discovered, we can now work out the traits of the potential offspring between a couple of any species, using a method called a genetic cross. In this lesson we will cover Higher Level Leaving Cert Biology Genetic Crosses and Evolution. This lesson will cover:

• Genetic Variation
• Evolution
• Heredity
• Normal Dihybrid Crosses
• Different Crosses
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of Genetic Crosses and Evolution!

When you look inside a cell, then inside the nucleus, keep zooming in and you'll see the organisms DNA  - the blueprint of life. It's crucial to have a good understanding of the fine structure of DNA (and of another similar molecule called RNA) before progressing through the rest of genetics. Next, we look at how cells are constantly copying their DNA and then dividing in two, themselves. After this we look at how cells read the  genetic code inside the DNA and use this code to manufacture proteins - and how we can use this information to our advantage to make proteins in the lab or in the factory. In this lesson we will cover Higher Level Leaving Cert Biology Genetics (DNA). This lesson will cover:

• Chromosomes
• DNA and RNA
• DNA Replication
• Cell Division
• Protein Synthesis
• Genetic Engineering
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of Genetics (DNA)!

All living organisms can be classified into five different groups - these are called the '5 Kingdoms of Life'. Two of these groups are animals and plants; the other three groups - monera (bacteria) , protista and fungi - are microorganisms. Microorganisms are living organisms that are so small that we can't see them with the naked eye - we need a microscope to see them. These tiny creatures dominate the planet and we must aim to have a good understanding of the different types of them, their structure, what they eat, how they reproduce and examples of ones that are both good and bad for us. In this lesson we will cover Higher Level Leaving Cert Biology Microbiology. This lesson will cover:

• The 5 Kingdoms of Life
• Monera
• Protista
• Fungi
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of Microbiology!

The cell is the functional unit of biology - everything alive either is a cell or is composed of cells. For this reason, a good understanding of the structure and function of the cell is imperative to the rest of biology. This lesson will study biomolecules - the chemicals that cells are made from; the different structures in a cell and what they do; how substances move in and out of cells; and how we use microscopes to study cells. After completing this lesson, you'll be ready to look at biology at another level. In this lesson we will cover Higher Level Leaving Cert Biology The Cell. This lesson will cover:

• Biolmolecules
• Animal Cell
• Plant Cell
• Plasma Membrane
• Cell Transport
• Microscope
• Exam Questions

With lessons, tests, hotspots, games and interactive videos, improve your knowledge of Biology in the topic of The Cell!
