Biology: What Do You Really Study?
Adapts and protects to ecosystems - to understand how living things work, change and communicate.
What Do You Study in Biology? Core Subjects, Year by Year
What do the degree courses cover?
Open a course to learn about its main topics and see what the work looks like in practice.
What do you learn in the course?Cell Biology?
Learn how the cell is built and how its parts cooperate to produce energy, transport materials, communicate and divide. Linking membranes, organelles, the cell skeleton and the cell cycle with normal function and diseases.
Main topics
- Membranes and substance transfer
- Organelles and energy production
- The cytoskeleton and communication
- Cell cycle and cell death
What does it look like in practice?
For example, a protein is followed from the moment it is created in the ribosome until it is secreted outside the cell and identifies where a malfunction will disrupt the pathway.
What do you learn in the course?General chemistry for biologists?
The course builds the chemical basis for understanding living systems. You learn the structure of atoms and bonds, amounts and concentrations, acids and bases, energy and equilibrium, with an emphasis on solutions and reactions relevant to cells.
Main topics
- Atoms, bonds and molecules
- mol, concentration and stoichiometry
- Acids, bases and buffers
- Energy and balance
What does it look like in practice?
For example, calculate how preparing a buffer helps maintain a stable pH despite adding acid to a biological system.
What do you learn in the course?genetics?
Learn how hereditary information passes between generations and how changes in it affect traits. We start with Mendel's laws and chromosomes and progress to linking genes, mutations, population genetics and mapping tools.
Main topics
- Mendelian inheritance
- Chromosomes, linkage and recombination
- Mutations and trait expression
- Population mapping and genetics
What does it look like in practice?
For example, a pedigree is used to infer whether a trait is dominant, recessive, or linked to the sex chromosome.
What do you learn in the course?Mathematics and statistics for biologists?
You learn the quantitative tools needed to design an experiment and interpret biological data. They deal with functions and rate of change, probability, distributions, confidence intervals and hypothesis testing, and sometimes work with statistical software.
Main topics
- Functions, change and growth
- Probability and distributions
- Data description and confidence intervals
- Hypothesis testing and regression
What does it look like in practice?
For example, they check if a treatment changed the growth rate of plants and also show the size of the effect and the uncertainty.
What do you learn in the course?Biochemistry?
The course explains how the chemical structure of living molecules determines their action. You study proteins and enzymes, carbohydrates, fats and nucleic acids, and the metabolic pathways that produce energy and build a cell.
Main topics
- Structure of proteins and enzymes
- Carbohydrates, fats and nucleotides
- Glycolysis and cellular respiration
- metabolic control
What does it look like in practice?
For example, glucose breakdown is followed and calculated where ATP and electron carriers are created and how the cell regulates the pathway.
Frequently Asked Questions About Biology
Is a degree in Biology difficult?
There is no single answer — difficulty depends on your background, the institution, and your chosen study pace. According to this site's estimate, The degree has a meaningful quantitative component that requires regular practice, but it is not the central focus of the program, and a large share of the reading material is in English. A good way to assess fit is to review the course map on this page: if most of the subjects interest you, the effort will usually feel worthwhile.
How long does a degree in Biology take?
Usually 3 years (Single-major, double-major, or combined program). Exact duration varies by institution and depends on course load and the track you choose.
Biology or Chemistry — which is right for me?
The degrees most closely related to Biology are Chemistry, Marine Sciences, and Biotechnology. Their differences are usually in emphasis rather than the overall subject, so the fastest way to decide is to compare their course maps — what you actually study in each program, year by year. You can also open the degree comparison tool to view the differences side by side.
Do you need a master's in biology?
In practice, usually yes: R&D roles in biotech and pharma require a master's or PhD. With a bachelor's alone, graduates work in lab technician, QA and scientific sales roles — so plan the next step early.
What is the difference between biology and biotechnology?
Biology is the broad science of living systems; biotechnology focuses on application — genetic engineering, drug development and bio-production. Biotech is more industry-oriented; biology is broader for research and medicine.
Is biology a stepping stone to medicine?
For some, yes: top graduates apply to graduate-entry medical programs (4 years). But it is a very competitive path — don't choose biology only as a backup plan.
Where can you study this?
Biology and life sciences are taught at all research universities and at colleges such as Tel-Hai and Oranim. Those aiming at industry may also consider biotechnology.
