| Since non-vascular plants live in moist, watery surroundings, what can their sperm cells do during reproduction? | they can swim to the egg cells |
| What are the structures that look like tiny leaves growing off the small stem that are the fuzzy green part of the moss called? | 1. the gametophyte |
| Describe what generates out of the gametophyte | 1. the sporophyte and it includes a long slender stalk with a capsule at the end |
| What does the capsule at the end of the sporophyte contain? | 1. spores |

| Why can vascular plants grow quite tall? Give two reasons | 1. they have very effective transportation systems through out the plant 2. vascular tissue gives the plant strength and stability |
| In seedless vascular plants spores grow into gametophytes that produce egg cells and sperm cells. Why must there be water avalable to them? | 1. so that the sperm can swim towards the eggs |
