Biology Chapter: Life Processes

All living things are composed of cells, making it the most important characteristic of life.

Plants are known for their extensive movement capabilities, similar to that of animals.

Respiration in living things involves taking in oxygen and releasing carbon dioxide.

Excretion is the process of taking in nutrients and energy from the environment.

Sensitivity in living organisms allows them to respond to their environment.

Reproduction in living things occurs through a process of cell division only.

Nonliving things can perform life functions similar to those of living organisms.

Nonliving things are capable of growth in terms of increasing size.

All living things exhibit some form of movement, including plants which can move around just like animals.

Respiration is a process that involves animals taking in carbon dioxide and releasing oxygen.

Excretion is important because all living things produce harmful substances that need to be removed.

Growth in living things refers to the accumulation of energy without any increase in size.

Sensitivity in living organisms allows them to react to environmental changes such as light or temperature.

Nonliving things can carry out life functions like respiration or reproduction.

Plants are known to reproduce solely by producing seeds that can germinate into new plants.

Living things are categorized as organisms that do not possess cells.

Cellular Structure

Cells are the basic building blocks of all living things.
A cell is the smallest unit of organization in a living thing.

Movement

Living things exhibit movement.
Humans and animals move around (walking, flying, swimming).
Plants exhibit movement in parts like buds and leaves, tracking sunlight.

Respiration

Respiration is the process of exchanging gases.
Living things take in gases and eliminate gas wastes.
Animals take in oxygen and release carbon dioxide.
Plants take in carbon dioxide to produce food.

Excretion

Living things produce substances that may be harmful.
Excretion is the removal of these harmful substances.
Wastes include carbon dioxide, excess salt, water, urine, and undigested food.

Growth

Living things increase in size in a process called growth.
Growth is fueled by energy gained from food.

Sensitivity

Living things react to changes in their environment.
Reactions can be to touch, light, heat, cold, or sound.
For example, the makahiya plant's leaves close when touched.

Reproduction

Living things produce new organisms of their own kind.
This includes offspring like humans (babies), cats (kittens), birds (eggs), and plants (seeds).
Plants make seeds that germinate and grow into new plants.

Nonliving Things

Nonliving things do not carry out life functions.
Examples are metals, air, water, and soil.
Nonliving things lack cellular function and cannot perform activities like living things.
Nonliving things have no methods of movement, cannot grow, cannot reproduce, and do not live or die.
Nonliving things are immobile or motionless.
Nonliving things don't need energy from their environment to survive.
Nonliving things don't need food, water, air, or shelter to survive.
