Lesson 1 Classify Plants
What are flowering plants?
Plants with seeds that grow flowers.
What do plants need to live and grow?
food, air, water, and space
Where does water enter a plant?
the root hairs on the roots
What does it mean to reproduce?
To make more of the same kind
What is the 2nd step in the life cycle of flowering plants?
growth

Where do plants get their energy from?
the sun
What is a taproot?

What is pollination and why is it important?

Where do plants make their food?
What is the purpose of a stem?
support the leaves, flowers, and fruits of plants

tiny holes
What are the 3 things roots do?
keep plants stable, store food made by the plant's leaves, take in water and materials called minerals from the ground
