|---|---|
| Plants without tubelike structures to carry water are called ________________. | nonvascular plants |
| Two types of nonvascular plants are mosses and _________________. | liverworts |
| Two types of nonvascular plants are ___________ and liverworts. | mosses |
| Mosses are anchored in place by hairlike fibers called ________, which take the place of roots. | rhizoids |
| Mosses are anchored in place by hairlike fibers called rhizoids, which take the place of ______________. | roots |
| Rhizoids, like other parts of mosses and liverworts, can take in water from their ______________. | surroundings |
| While most common plants grow from seeds, mosses and liverworts grow from cells called ______________. | spores |
| Ferns and club mosses are vascular plants, but they are like mosses because they use spores to _______________. | reproduce |
| Because vascular tissue is made of long, tubelike cells, ______________ plants can grow taller and thicker than mosses. | vascular |
| The leaves, or fronds, of a fern grow from a ______________, which is an underground stem. | rhizome |
| The bottom sides of some fronds are covered with ________________. | spore cases |
| Spores are spread around the fern when the spore cases __________________. | pop open |
| Mosses and ferns both use ________ to reproduce. | spores |
| A plant that reproduces with one type of cell is reproducing by ___________ reproduction. | asexual |
| Moss spores grow into moss plants with both ______________ and female branches. | male |
| Moss spores grow into moss plants with male and ______________ branches. | female |
| Male branches produce ______________, while female branches produce eggs. | sperm |
| Male branches produce sperm, while female branches produce ______________. | eggs |
| In sexual reproduction, a male sex cell ________________ the egg, which grows into a stalk topped with a spore case. | fertilizes |
| Spores that are released onto damp ground grow into new _____________. | moss plants |
| Both mosses and ferns alternate sexual and asexual reproduction, a process called _______________. | alternation of generations |
| Fern spores grow into heart-shaped plants that produce _________ and female sex cells. | male |
| Fern spores grow into heart-shaped plants that produce male and ______________ sex cells. | female |
| If male and female cells from the plant join, the fertilized egg grows into a ______________. | new fern |
| To find the ancestors of plants, scientists first looked at other organisms that carry on _____________. | photosynthesis |
| Green algae are like plants in various ways, including having strong _______________ containing cellulose. | cell walls |
| Green algae and plants store food as _____________. | starch |
