The organelle of a plant that provides photosynthesis. | The chloroplast - (green) |
What does the cuticle do for a plant? | coats the top of the leaves and keeps plants from drying out |
Sporophyte stage produces spores by means of what type of reproduction? | Asexual reproduction (one parent - spores) |
Seeds are produced by what stage of plant reproduction? | gametophyte stage (sexual reproduction - seeds) |
Examples of nonvascular, seedless plants | moss, liverwort, hornwort |
Examples of vascular, seeded plants | flowers, evergreens, other trees |
Plants transport water and nutrients in the ___________ (vascular tissue) | xylem |
