Questions (Be able to answer as multiple choice or short answer).
1.
Where do the seeds of a pine tree form?
Between the scales of the cones
2.
What are three examples of cone-bearing plants? Pines, firs, spruce
3.
What is the main job of a fruit?
Protect the seeds inside
4.
How are the seeds of cone-bearing plants and flowering plants different?
Cone bearing – unprotected seeds; Flowering plants – protected seeds
5.
What four things do plants need to live?
(1) air, (2) nutrients, (3) water, (4) sunlight
6.
What does a plant need to carry out photosynthesis?
(1) sunlight, (2) carbon dioxide, (3) chlorophyll, (4) water
7.
What provides the energy for photosynthesis to take place? sun
8.
What provides most plants with nutrients? soil
9.
What would happen if there were no carbon dioxide in the air?
Photosynthesis could not take place. Then, plants could not make food and give off
their oxygen. The animals would die without oxygen and food.
Be able to put the steps of photosynthesis in order.
1. Chlorophyll in the leaves traps the sunlight.
2. Energy from the sun begins the food making process.
3. Carbon dioxide enters through the plants leaves and water through the roots combine with
other nutrients to make sugar.
4. Oxygen is given off as a waste product.
