Lesson 2 Flashcards
____________ is the study of life
BIOLOGY
____________ study th estructure, function, growth, origin, evolution and distribution of living organisms.
BIOLOGISTS
CHARACTERISTICS OF LIFE
They are made up of cells
They grow and develop
They are capable of reproduction
They exhibit metabolism
They respond to their environment
They maintain homeostasis
Pieces of Evidence
Fossil Records
Rock Layers
Geologic Processes
_________________- Living things work as a system, at the same time they cannot be separated from non-living things since they are both operating as a system
BIOLOGICAL SYSTEM
BIOLOGICAL SYSTEM
A _____________ is an organized group of interacting parts.
BIOLOGICAL SYSTEM
A _____________ includes organs that interact.
BIOLOGICAL SYSTEM
An ___________ includes living and nonliving things that interact
ECOSYSTEM
BIOLOGICAL SYSTEM (ORGANIZATION)
Cell
Tissue
Organ
Organ System
Organism
Population
Community
Ecosystem
Biome
Biosphere
_______________- Basic unit of life, a system of chemicals and processes; which denotes that all living things are composed of ___________
CELL
___________________- Living things cannot live alone, their survival depends on how they interact with the environment
INTERACTION WITH THE ENVIRONMENT
INTERACTION WITH THE ENVIRONMENT
Organisms have evolved to ________ and ____________ with other organisms
LIVE AND INTERACT
INTERACTION WITH THE ENVIRONMENT
_____________ deals with the interactions of living organisms with one another and their environment.
ECOLOGY
Living organisms use a source of energy for their metabolic activities.
ENERGY AND LIFE
ENERGY AND LIFE
Some living organisms capture the light energy and convert it into chemical energy in food.
AUTOTROPHS
ENERGY AND LIFE
Some living organisms use chemical energy stored in molecules obtained from food.
HETEROTROPHS
Organisms’ structures fit with its functions.
FORM AND FUNCTION
FORM AND FUNCTION
Features that are common in different organisms because their common ancestry also possessed this feature.
Ex: pentadactyl limb of humans, cats, bats, whales….
HOMOLOGOUS STRUCTURES
FORM AND FUNCTION
Features in different organisms that serve a similar function, however they are structurally different since they evolved independently (their common ancestor does not posses this feature)
Ex: wings of birds, bats, and insects
ANALOGOUS STRUCTURES
Traits of parents are being passed from one generation to the next generation
REPRODUCTION AND INHERITANCE
TYPES OF REPRODUCTION
ASEXUAL AND SEXUAL REPRODUCTION
[NOTE]
TURTLE:
-Not all turtles are tortoises…
-Flipper boi
-Flat, streamlined shell
-Turtley in the sea
-Eats both plants and animals
TORTOISE:
-…but all tortoises are turtle.
-Chonky foot
-Dome-shaped shell
-Lives mainly on land
-Veggie is love, veggie is life.
Organisms must maintain homeostasis to survuve in diverse environments.
REGULATION
REGULATION
_____________ is the maintenance of constant internal conditions. All living organisms must live in a ______________.
-HOMEOSTASIS
-STABLE ENVIRONMENT
REGULATION
Cells of the body are surrounded by small amount of fluid, and normal cell functions depend on the maintenance of cell’s fluid environment including __________, ___________, and ___________
-temperature
-volume
-chemical content
