RECOGNIZING LIVING THINGS
Objectives: At the end of this lesson, students should be able
to:
- Identify and distinguish between living and non living things.
- State the characteristics of living things.
- Give examples of levels of organization.
- State the complexity of organization in higher organisms.
Recognizing living things requires careful attention to the characteristics that distinguish them
from nonliving matter. Living organisms exhibit the capacity to grow, respond to their
environment, and carry out vital processes that sustain life. By observing patterns such as
movement, reproduction, and the use of energy, we can identify the presence of life.
Ultimately, the ability to recognize living things depends on noticing these essential traits and
understanding how they work together to maintain an organisms ongoing existence.
BIOLOGY AND LIVING THINGS
Living things show these characteristics in different ways, but the overall pattern remains the
same. Growth allows organisms to increase in size and change form as they develop. Response to
the environment helps living things react to stimuli such as light, temperature, touch, or chemical
signals. Living organisms also carry out metabolism, which is the set of chemical reactions that
release and use energy. Without these processes, life cannot continue.
Another important idea is that living things are organized at different levels. For example, cells
form tissues, tissues form organs, and organs work together to form body systems. At the highest
level, these systems combine to make a complete organism. As the levels of organization
increase, the structure becomes more complex and specialized. Higher levels of organization
allow organisms to perform more coordinated and efficient functions, such as digestion,
circulation, and reproduction.
Overall, studying biology and living things helps us understand not only what life is, but also how
living systems are structured and how they function together to survive.
DEFINITION AND BRANCHES OF BIOLOGY
Definition of Biology: The term biology is coined from two Greek words
—bios meaning life and logos meaning to study. Hence, biology can
, simply be defined as the study of life. In other words, it's the study of
plants and animals.
BRANCHES OF BIOLOGY
- Zoology: Zoology is the study of animals
- Botany: Botany is the study of plants.
Other branches includes:
- Ecology: it is the study of plants and animals in relation to their
environment.
- Morphology: it is the study of external feature or parts of a living thing.
- Anatomy: it is the study of internal structure of living things.
- Genetics: it is the scientific study of heredity and variation in living
things.
- Physiology: It is the study of how living things function.
LIVING THINGS AND NON LIVING THINGS
Everything on earth can be classified as living and non living things.
Living things are plants and animals that have life, While non living things
are things that do not have life in them. Examples of living things are
man, sheep, hibiscus,cow etc while non living are books, air, stones,
tables, houses and so on
CHARACTERISTICS OF LIVING THINGS
Living things are distinguished from non living things by these
characteristics:
