Module-2: Lesson-1: Levels of Organization
Living Things
Cells
Unicellular
One cell organisms
Multicellular
Organisms with more than one cell
Cells grow, divide, and produce new cells.
The first cell can be
any type
.
Nerve cells
Muscle cells
This is done through a process called
cell differentiation.
As organisms grow, new cells are produced
Number of cells increase and they are organized into groups with similar cells.
Blood cells
Bone cell
Have
specialized cells
that perform different activities.
Specialized cells are cell that are designed for a specific function
37.2 trillion cells in humans
Similar type of cells group together to make
tissues
.
Tissues
The tissues work together to perform a specific function
Plant
Vascular
Transports water, minerals and food to parts of the plant.
Ground
Performs photosynthesis that makes the food neccesary for plant growth & provides support & storage
Dermal
Protects the surface of the plant & reduces water loss.
Animal
Nervous
Carries messages to & from the brain
Connective
Provides structure & support & connects all other tissues together.
Muscle
Causes movement
Epithelial
Forms protective layer of skin & other organs.
Similar tissue combine to form
organs
in order to perform complex tasks
Organs
For example: Leaf
Vascular Tissue
Transports food and water
The function of the leaf is to do photosynthesis and provide nutrients to the whole plant
Ground Tissue
Makes food
Dermal Tissue
Covers the outer surface of the leaf
For example: Stomach
Nervous Tissue
Send & receives messages from the brain
The function of the stomach is to breakdown food
Epithelial Tissue
The lining of the stomach
Muscle Tissue
Contraction & relaxation
Connective Tissue
Connects tissues
Different organs work together to complete a series of tasks. They form
organ systems
.
Organ system
For Example:
Humans
Digestive system
Liver
Small intestine
Large intestine
Stomach
Plants
Root system
Roots
Absorb water and minerals and support plants to stand upright.
Shoot system
Leaves
Flowers
Transport water and nutrients throughout the plant.
Stems
Many systems work together to carry out all the jobs necessary for the survival of the
organisms
.
Types
Nervous System
Connects, transfers & processes information to & from the brain.
Skeletal System
Provides movement, support & stability
Digestive System
Breaksdown food to give energy to the cells
Cardiovascular system
Transports oxygen and nutrients to the whole body
Excretory system
Eliminates waste from the body
Lymphatic system
Integumentary system
Endocrine system
Reproductive system
Respiratory System
Provides gaseous exchange
Muscular System
Provides movement & support
Organisms
Humans
Each new organ system depends on other systems and cant work alone. For example: The digestive system cant work without the nervous, respiratory, and circulatory system.
Plants
Root and shoot system helps the plant to grow and produce new cells.
