1. The largest group of gymnosperms is the CONIFER
2. Unlike seed plants, seedless plants must have water to reproduce.
3. List the function of roots: anchors the plant to the soil, collects and transports water and minerals and it
sometimes stores food.
4. Ovules develop into seeds.
5. A houseplant that is bending toward a sunlit window is displaying phototropism (tropism).
6. Monocots have
flower petals in sets of 3s and the vascular tissue runs parallel.
7. Leaves become red and orange in autumn because the plants are allowing their cholorplast to die off and
the red and orange pigments are showing through.
8. The sperm cells of a flowering plant are contained in the pollen located on the anther.
9. Pollination occurs when pollen grains are transported from anters to stigma.
10. After fertilization occurs, the ovary develops into fruit.
11. Two groups which ALL plants are grouped into are vascular and nonvascular
12. The long, slender part of the pistol is called the style.
13. Carbon dioxide enters and oxygen is released from a leaf through the stoma or stomata.
14. When stomata are open, water vapor can leave the leaf in a process called transpiration.
15. Plants use oxygen to break down the glucose for energy in a process called cellular respiraton.
16. Cycads, conifers, ginkgoes and gnetophytes are examples of gymnosperms.

18 Describe reproduction in seed plants. Use the vocabulary words listed above.
During pollination, the sperm is released from the pollen and joins with the egg. This is called fertilization and it
forms a zygote. Once the zygote is formed, it can develop into a seed. When the seed lands in the right
environment it can begin to germinate. Germination is when the embryo begins to push out of the seed and
begins to grow.
