Biology
What is Biology?
The science that studies life and living organisms.
What does BIOS mean?
Life
What is the first step of the Scientific Method?
Observation
What is a microscope?
An instrument used to observe objects or structures that are too small to see clearly with the naked eye.
What is the basic structural and functional unit of life?
The cell
What does the word “Biology” mean?
The study of life.
What does LOGIA mean?
Study or science of
What is a hypothesis?
A testable possible explanation or answer to a question.
Why are microscopes important in Biology?
They allow us to observe microscopic structures and organisms.
Name four characteristics of living things.
Cells, nutrition, irritability, growth, respiration, reproduction, and homeostasis.
What is a living organism?
An organism that carries out processes necessary to maintain life.
Which branch of Biology studies animals?
Zoology
What step comes after asking a question and helps you learn what is already known about the topic?
Research
Who observed cork and used the term “cells” to describe the structures he saw?
Robert Hooke
What is irritability?
The ability of an organism to detect and respond to changes in its environment.
Why is Biology important in our everyday lives?
It helps us understand living organisms, health, the environment, and how life works.
Which branch of Biology studies heredity, genes, and inherited characteristics?
Genetics
Put these steps in the correct order: Hypothesis, Observation, Conclusion, Research, Question, Experimentation, Analysis.
Observation → Question → Research → Hypothesis → Experimentation → Analysis → Conclusion.
Who was one of the first scientists to observe microorganisms using microscopes?
Anton van Leeuwenhoek.
What is homeostasis, and why is it important?
Homeostasis is the ability to maintain relatively stable internal conditions. It is important because cells need stable conditions to function properly.
A student wants to understand how a disease affects the human body. Why would Biology be important for this investigation?
Because Biology studies living organisms and their processes, including how diseases affect the body.
A scientist studies how organisms interact with each other and with their environment. What branch of Biology is being used?
Ecology
A student notices that a plant near a window grows faster than a plant in a dark room. They ask: “Does the amount of light affect plant growth?” Write a possible hypothesis.
If a plant receives more light, then it will grow more because light is important for photosynthesis.
What is an important difference between Robert Hooke’s and Anton van Leeuwenhoek’s observations?
Hooke observed structures in cork and called them cells, while Leeuwenhoek observed living microorganisms.
A plant grows toward sunlight, a person pulls their hand away from a hot object, and a dog eats food. Which characteristics of life are demonstrated?
The plant and person demonstrate irritability, while the dog demonstrates nutrition.
