Biology Worksheets, Notes, and Quizzes (PDF and PNG)

This is a collection of free biology worksheets, notes, handouts, slides, study guides and quizzes. Most content targets high school, AP biology, genetics, anatomy/physiology, immunology, and biology 101 and 102 in college. There is also biochemistry and physics for biologists. However, some resources are at the grade school and middle school level.

The files are PDF, PNG, JPG, and formats using Google Apps for Google Classroom. Most of the time, these formats are interchangeable. So, if you see something you like, but want a different format, just let us know. Print these resources, make transparencies and slides, etc.

In the interest of quick load time, not all of the images are shown. If you’d rather see them all, just contact us!

How to Pass Form 1 Biology at KCSE Level

Start by listing out the topic segments, like cell biology, infection and response and homeostasis. Break these into sections and plot them in your schedule. Don’t try and cram too much into one revision session; instead, stick to one topic at a time to make sure you really understand it. 

Half an hour at a time on each biology topic should do the trick. It’s long enough that you can dig deep during the session, but short enough that you won’t get bored and start daydreaming. 

Here are some top tips for creating an effective revision timetable and learning how to revise for Form 1 Biology:

• Use the exam board specification as a checklist and tick off each learning outcome as you do it 
• Start your revision sessions with an easier topic to build your confidence and then move onto a more difficult topic 
• Break topics down into smaller sections and sprinkle them throughout your schedule 
• Make sure you leave plenty of time for breaks. Time away from revision can help information sink in, especially for heavy subjects like biology 

Create a Revision Guide and Summary to Pass Form 2 Biology 

Find out the main topic areas covered in a Biology exam. Split these up into different sections in your revision guide and pull out notes from each class and summarize them.

It helps to have a “factsheet” at the front of each section that highlights key formulas, units of measurement and any other key terms that relate to the topic.

After the factsheet, try and summarise each topic in a paragraph or two. This ensures you fully understand it and aren’t just copying your class notes without taking the information in.

Get and Use Past Papers and Answers for Form 3 Biology

Biology exams are different from other exams. They require you to provide a mixture of answers, from short essays and explanations, to calculations and practical information. 

Getting familiarised with what a Biology exam paper looks like will help you stay calm and focused during your actual exams. Free Past papers are key for this. They allow you to experience an exam-like situation on your own terms.

For best results, work on practice papers in a faux exam environment. 

That means:

• Giving yourself a time limit
• Turning off your phone and getting rid of distractions
• Not looking at your Biology notes when attempting the questions
• Marking your answers and identifying key areas for improvement

Use Study Groups -Form Four Biology Exam papers

Two minds are better than one, and multiple minds are better than two. get classmates and create a study group where you can share Biology ideas, test each other, and make studying fun. 

Try and meet at least once a week for an hour to go over your notes and share your knowledge. This also makes studying more enjoyable, because you can play games and quiz each other. 

In Revising Biology, Consider doing activities such as: 

• Designing a slideshow presentation about a specific process or formula
• Creating a group revision guide
• Quizzing each other on key topics 
• Discussing ideas and hosting biology-related conversations

Describe the digestion of a starchy meal along the human alimentary canal. S (13 mks) Answer-Starch in food is first broken down in the mouth by action of teeth/ chewing; This increases the surface area exposed enzyme action; saliva contains salivary amylase which breaks down some starch to maltose; saliva has a slightly alkaline pH which is optimum for the enzyme; The food moves down to the oespophagus and stomach; where the acidic pH, due presence of dilute Hcl, prevents further action of salivary amylase; In the duodenum, pancreatic amylase continues digestion of starch to maltose; Pancreatic amylase is produced in the pancrease; and enters the duodenum through pancreatic ducts; the acidic chyme is neutralized by the sodium bicarbonate in bile/ pancreatic juice; Maltose digestion continues in the ileum; whose walls secrete succus entericus/ intestinal juice; which contains enzyme maltase; which breaks down maltose to glucose; (Max 13 marks) (b) Describe the process of urea formation. (7marks) answer Excess amino acids / proteins; are transported to the liver 2. (a) Describe how gaseous exchange occurs in terrestrial plants. (13 marks) Answer Gaseous exchange takes place in a spongy mesophyl During the day air diffuses into large air spaces of spongy mesophyll; through stomata; the Carbon (IV) Oxide in the air diffuses into Photosynthetic cells; in solution form; during photosynthesis Carbon (iv) Oxide is used while oxygen is produced. Oxygen diffuses out of the leaf; through stomata; During the night; air diffuses into the air spaces (of spongy mesophyll), the air dissolves into film of moisture; then oxygen diffuses into the cells; and is used in respiration during which carbon (iv) oxide is produced, the Carbon (iv) Oxide diffuses out of the leaf; through stomata; due to concentration/diffusion gradient; Gaseous exchange takes place through epidermis (of young leaves and stems); epidermis of the root carries out gaseous exchange with air in the soil; some plants have pneumatophores/breathing roots; in which gaseous exchange occurs through lenticels; (found in
