get water from soil
stay in one place
produce their own food
grow their whole life
usually green
What do roots do?
Roots absorb water and minerals
Roots anchor the plant in the soil
What does adaptation mean?
A change to suit an environment
What does germination mean?
The process of sprouting from a seed into a seedling
What do animals breathe in? What do they breathe out?
1. Oxygen
2. Carbon Dioxide
What do animals and plants have in common?
Both need water
Both animals and plants grow
Both animals and plants like sunshine
What are the two types of roots?
Taproots are a single root growing downwards (ex. Dandelions)
Fibrous roots are spreading roots
What does disperse mean?
To spread out
What is a life cycle?
A series of stages of development
Where are some areas we can grow our food?
Greenhouse
Home garden
Farm
Orchard
What do plats need?
Light
Air
Water
Space
Warmth
Food
What do stems do?
Stems store water and make food
Stems protect plants with it’s sharp thorns
Stems wind around its support as it grows (ex. vines )
Stems are covered in a protective layer of bark (ex. Pine tree)
What are the two major types of pollination?
Animal pollination
Wind pollination
What is a bulb?
A bulb is a modified stem that develops undergroround as a bundle of stored nutrients for a flowering plant.
What to plants release?

What are the parts of a cacti
The stem
Spines
Roots
What are some environmental conditions that threaten plant life?
Flooding

Wildfires
Tornados
What are some ways that plants adapt themselves to their environments?
Turns toward light (like a sunflower)
Stores water in its stem (like a cacti’s stem that stores water).
Protects itself against animals (like a rose with thornes).
Appears attractive to pollinators (like a flower to a bee).
What are the steps for seed germination?
First, the seed sends a root downward into the soil to take in water
Next, it sends a shoot upward to get sunlight
Finally, once the baby plant grows leaves, it can start making its own food using sunlight.
The germination process is then complete
What do plants breathe in?
Carbon dioxide
What are some characteristics of cacti
They store water
Able to survive in dry and hot areas
Come in many shapes and sizes
Have a thick waxy stem covered with spines that store water
Some cacti even have stems that can absorb water from the air
They have prickly spines which protect cacti from animals that want to eat or get water from them

Farming
Construction
Factories
Gardening
What are three types of seed dispersal?
By water
By animal
By wind
What are some examples of bulbs?
Garlic
Onions
What are some ways we use plants in our lives?
Medicine
Food
Clothing
Shelter
Rubber
Paper
Furniture
