What is a seed?
A seed is an undeveloped plant with stored food in a protective covering.
100
What is pollination?
The transfer of the pollen of a plant to the pistil of a plant.
100
Name one way seeds are carried away.
They can be carried away by wind, animals, water, or the plants can send it away.
100
What is a spore?
A spore is a cell in a seedless plant.
100
What do flowering plants use to reproduce?
Seeds!
200
What is germination?
The process of a seeding sprouting to a new plant.
200
What is fertilization?
The joining of the female cell and the male cell to create a fertilized egg.
200
What fractions of plants are flowering plants?
8/10 of plants.
200
Name a plant that has a spore.
Ferns and mosses have spores.
200
What is the order in which these processes occur? -Fertilization -Germination -Pollination
First is pollination, then fertilization, then germination.
300
What is the biggest seed in the world?
The coconut seed.
300
What is the ovary of a plant?
The structure of the plant containing the egg cells.
300
Do all seeds grow to be a plant?
No. Most do not.
300
If 8/10 of plants are flowering plants. What fraction of plants have spores?
2/10 of plants have spores.
300
Briefly tell the life cycle of a flowering plant.
First there is a full grown plant. The plant goes through pollination, then the plant grows through fertilization, after that the plant grows a fruit around the seed. When the fruit falls and decays the seed gets carried away. It finally germinates and becomes a full grown plant.
400
What does a plant need in order to germinate?
Sunlight, nutrients from social, and warm temperatures.
400
Name two things that help plants pollinate.
Things that help plants pollinate are insects, birds, mammals, wind, or water.
400
Why don't all seeds grow to be plants?
There are many different reasons. They needs very special circumstances to grow and if they are too close to the parent, they get eaten, or the weather is not right they will not grow.
400
Name one way how spores different from flowering plants?
They have a different life cycle. They dont have flowers. They don't have pollen. They don't have pistils.
400
Do all plants grow from seeds?
No, some grow from spores.
500
What are the steps of germination?
The fruit decays, the seed sends the stem and leaves to grow, it becomes a seeding, then it becomes a full plant.
500
Why is pollination and fertilization important to humans?
It is important because without plants there would be not oxygen! We need this to happen so plants will grow and we can live
500
What happens after a plant egg is fertilized?
The seeds begin to grow with a protective fruit around it.
500
Can spores survive in extreme temperatures and droughts?
Yes! They are tough little cells!
500
Why do plants need animals?
Plants need animals because they help move pollen to pistils for pollination. They also help because they carry seeds away from their parent plant so they can have a chance to grow and germinate.
