What Plants Need
•
•
•
•
Water
Light
Soil (for nutrients)
Air
What parts does a plant have?
flower
Makes seeds for new
plants to grow
leaves
Take in air and light that
plants need to make food
stem
Moves water through the
plant; supports the plant
above ground
roots
Take in water and minerals;
hold plant in the soil
Parts of a Seed
• A tiny seedling plant
• Food
• Seed coat
seedling plant
food
seed coat
Seeds
• Most plants
reproduce by making
seeds.
• Can be found in
flowers or cones
• Can be spread in the air, water,
or by animals
Life Cycle of Plant
A seed is planted
and given water.
The seed
germinates
and begins to
grow roots.
The seedling
develops leaves
for photosynthesis.
The adult plant
produces seeds to
begin the cycle again.
The seedling
continues to
grow.
Photosynthesis
The food
making
process of
plants
Water and
nutrients
Plant Adaptations
• Parts of a plant that help
it adapt to meet its needs
in its environment
– Tendrils (help to reach
sunlight)
– Thorns and spines (protect
from being eaten)
– Spines/modified leaves
(conserve water)
– Shallow roots (absorb the
most water)
Inherited Traits of Plants
• Plants have traits they get from the parent
plant that help them survive in their
habitat.
• Inherited traits in plants include color, size,
shape, and texture of the plant.
Needs of Animals
• Oxygen – through lungs or gills
• Food – energy from eating plants, other
animals, or both
• Water – from drinking in lakes or ponds or
from food
• Shelter - protects from weather and other
animals
• Light
• A way to dispose of wastes
Inherited Traits
• Examples: brown fur, long ears, ability to
spin a web, ability to swim

Metamorphosis
A change in the form or structure of an animal, usually
from birth to adulthood

The Frog Life Cycle
Frogs go
through a
metamorphosis,
or change, as
they grow.
