a.)When conditions are right, a seed will start to grow, or_______________.
b.) What do plants and animals need to live?
a.) germinate
b.) Food, air, water and space to live and grow.
A tree that makes cones is a(n)_______ tree.
coniferous
Bees, wind, and water can________flowers.
pollinate
a.) All the leaves and their parts make up a plant's leaf_____________.
b.) How does a leaf help a plant to live?
a.) system
b.) They help make food, balance the amount of water plants take in, and protect the plant from being eaten.
A(n)___________tree loses all its leaves in the fall.
deciduous
A new plant that has just grown out of the soil is a(n)_________.
seedling
A new plant uses food stored in a(n)_________.
seed leaf
A(n)______plant no longer lives on Earth, but a(n)_______ of its remains might be found.
extinct, fossil
Before a seed can become a plant, the seed must
a.) germinate
b.) be pollinated.
c.) make food.
d.) flower.
a.) germinate.
A cactus stores the most water in its:
a.) roots.
b.) leaves.
c.) stems.
d.) flowers.
c.) stems
What fossil is made when minerals replace plant parts, while water breaks the parts down and carries them away?
petrified wood
Which of the following is an example of scattering seeds?
a.) pollen sticking to a bee
b.) wind blowing pollen
c.) apples growing on a tree
d.) burs sticking to a dog's fur
d.) burs sticking to a dog's fur
What do a plant's leaves need to make sugar?
Air, water, and energy of sunlight
Explain why all of a plant's roots and their parts are called a system.
All the parts work together to live and grow.
How do scientists learn about plants that are extinct?
By studying fossils.
Choose one way that plants can be sorted into two groups. Explain how the plants in the two groups are alike and different.
Deciduous and coniferous . Deciduous trees lose and grow leaves. Coniferous grows cones. The flowers from the trees and the cones both make seeds.
Bees visit the flowers on apple trees to get food. How might a disease that kills bees affect the number of apples the trees make?
Bees carry pollen to the part of the flower that makes seeds. If bees don't carry the pollen, the seeds cannot be made which would make fewer apples.
What are the parts of a seed?
Seed coat, tiny plant and seed leaf.
What are two ways that animals scatter seeds?
Seeds are carried to new places by animals that eat fruit with seeds. The seeds pass through the animal's body.
Some seeds are carried along when they stick to an animal's fur.
Describe two kinds of plant parts that can make seeds.
Flowering plants (deciduous) grow flowers to make seeds.
Coniferous tree grow cones to make seeds.
Flowers and cones
Describe the life cycle of a plant starting with a seed being planted.
1.) Seed is planted.
2.) The seed germinates - stem grows upward and root grows downward.
3.) Seedling - A small plant grows leaves. It can begin making sugar for food.
4.) Adult plant with seeds - if the seeds germinate they grow into new plants.
Describe how a flower makes a seed.
A flower makes pollen. Animals and wind pollinate a flower by moving the pollen to the flower part that makes seeds.
a.) How do stems help a plant?
b.) How are roots and stems alike and different?
a.) A stem holds up the plant's leaves, flowers and fruits.
b.) They both support the plant. Stems move water and minerals from the roots to the leaves. Roots take in the water and minerals from the soil.
How do roots help a plant?
The roots hold the plant in the ground.
List the main parts of most plants.
Leaves, roots, stems, and flowers.
