1. All plants have cells.
2. All plants need sunlight, water, and carbon dioxide to live.
3. Know where the chloroplast is located in a plant cell.
4. A pine needle and a tulip leaf are both kinds of leaves.

6. Daisy’s have a flexible stem because they do not need the support of a woody
stem.

10. Plants turn sunlight into energy for reproduction.
11. A fern grows from spores, not seeds.
12. A spore is a single tiny cell.

15. Describe the process of photosynthesis in detail.
Plants take in carbon dioxide, water and sunlight energy, and turn those things
into sugar.
16. How are taproots and fibrous roots different and how are they alike?
They are alike because both anchor plants and absorb water and minerals from
the soil. They are different because fibrous roots spread in many directions.
Taproots are large roots that grow straight down.
17. Explain how a grass is pollinated and then fertilized.
Wind blows the pollen from grass into the pistil of another grass plant. A
pollen tube grows from the pollen into the ovary, where the pollen and the egg
cell combine and fertilization takes place.
