Download Organisms can be classified into two major groups

How are organisms classified?
• Organisms can be classified into two major groups-plants and
animals
• Each plant or animal has a unique pattern of growth and
development called a life cycle.
•  Plants are divided into flowering and non-flowering
•  Animals are divided into vertebrates and invertebrates
•  Vertebrates include fish, amphibians, reptiles, birds, and
mammals
How are plants classified?
• Plants have many parts and make their own food.
•  Some produce flowers while others do not.
•  Flowering plants are plants that make seeds within flowers (ex:
grass, roses, fruit trees)
•  Some flowers become fruit.
•  Non-flowering plants are plants that make seeds within cones or
produce spores instead of seeds. (ex: ferns, mosses, cedar trees,
pine trees)
What is the life cycle of a seed?
• The life cycle of a seed plant begins with a seed
• Seeds need water and warmth to germinate (begin to grow).
• Once seeds begin to grow, they become seedlings.
• Roots begin to grow and take in nutrients and water from
the habitat.
• The stem starts to grow toward light and the first leaves
form on the stem.
• When the plant is fully grown it is called a mature plant.
• Mature plants develop flowers or cones, which produce seeds.
