IB Biology
IB Biology is a course that explains the phenomenon of life and organisms. Biology is said to be the only living subject, so the learning never ends and biologists are always discovering new things about this course. Another fascinating fact about biology courses is that there are millions of different species on this blue planet, which opens up a wide range of specifications and mastery to achieve. Students learn about cell theory, the chemistry of living things, plant science and genetics, among many other topics to further their understanding of and learning about biology.
The IB Biology syllabus consists of topics divided into 11 sections:
- Cell Biology
- Molecular Biology
- Genetics
- Ecology
- Evolution and Biodiversity
- Human Physiology
- Nucleic Acids
- Metabolism, Cell Respiration and Photosynthesis
- Plant Biology
- Genetics and Evolution
- Animal Physiology
Engaging students is a key priority for our IB Biology tutors, especially in an online setup. For IB Online Academic Tutoring in Biology, there is inspiration all around – but it can still be difficult to make the subject more interesting and accessible to students. Learning through activities facilitates deep learning. Online academic tutoring sessions can help assess student’s knowledge and retention of biology through online quizzes and assignments that can be evaluated digitally too. Instant feedback and corrections save time and make sessions more streamlined for students.
IB Biology Syllabus Higher Level (HL) and Standard Level (SL)
Let’s discuss the topics in detail above, each section of the topics is having a subdivision of topics and is grouped according to level into the IB Biology HL (Higher level) and SL (Standard Level). The IB Biology also offers Optional IB Biology topics in the HL subjects. Therefore, IB Biology Syllabus divided into these three groups, those are as follows:
- IB Biology HL topics

Topics of IB Biology SL & HL
IB Biology SL Topic
These are the SL Topics of IB Biology given below in the table format, with a short concept description of each SL IB topic, those are as follows:
Cell Biology
Introduction to Cells | The core concept about this topic is having the understanding the correlation of cell with the human body, Because all living organisms are made of cells, Cells are the signal organisms which are evolved into the multicellular organism in a million of year. |
Ultrastructure of cells | The concept is about the cell structure compared to different types of organisms. |
Membrane Structure and Transport |
|
The origin of Cells and Division | The core concept of the topic is division, about the arisen endosymbiotic theory. Other than this to about the Mitosis process, Chromosomes and Mutagens, and the cycling of the cell cycle. |
Molecular Biology
Molecules to Metabolism, Water, Carbohydrates, Proteins, Enzymes, and lipids |
|
Photosynthesis | In the topic concentrated on plant cells, in this the topic describes the process of Photosynthesis due to carbon compounds in cells not in plants but present in all other organisms on the planet. |
Cell Respiration | This topic concept is the process of production of ATP. This means the release of energy from the organic compounds. And the Anaerobic cell respiration systems. |
DNA and the structure with Replication, Transcription, and Translation process | In this, the topic is all about the DNA and its formation of structure also the process of replication of DNA, Amino acid, Codons of three bases, Translation of mRNA and anticodons on tRNA. |
Genetics
Genes, Chromosomes, Meiosis, & Inheritance |
|
Genetic Modification and biotechnology of cells, DNA, etc. |
|
Ecology
Species, Communities, and Ecosystems | In this topic of IB biology covered the species, and different groups of interbreeding organisms, members of species of the same group, Detritivores are heterotrophs, Autotrophs, and the supply of inorganic nutrients, the ecosystems, etc. |
Energy flow, Carbon Cycling, Climate Change |
|
Evolution and Biodiversity
Natural Selection for Evolution and Its Evidence | In this the topic will cover the evolution of homologous structures, different species of the same families also the evidence of the natural selection of process by mother nature. |
Classification of biodiversity and Cladistics |
|
Human Physiology
Digestion and Absorption, Gas Exchange |
|
The Blood System and the defense against infectious disease | This topic covered the blood circulation system and white blood cells. The blood flow through veins and the separate circulation of Capillaries.
In the sinoatrial nodes, the impulses stimulate, the production of antibodies by lymphocytes, etc. |
Neurons, synapses, Hormones, homeostasis, and reproduction |
|
IB Biology HL Topics
These are the HL Topics of IB Biology given below in the table format, with a short concept description of each HL IB topic, those are as follows:
Nucleic Acids
DNA Structure of replication and the Translation, Transcription, and gene expression (HL Topic) |
|
Metabolism, Cell Respiration and Photosynthesis
Metabolism, Cell respiration, Photosynthesis | This topic involves the process of photosynthesis, Metabolism, and Cell respiration like NADP and ATP produced, Enzymes for energy, and Aerobic cell to the relation of ATP without the use of Oxygen. |
Plant Biology
Transport in the Xylem | This topic covers Osmosis and the Xylem. |
Transport in the Phloem | The transportation of organic compounds, high concentrations of solutes, and water uptake by Osmosis. |
Growth in the Plants | Plants’ hormones, Auxin cells, and efflux are covered in this topic. |
