| Question | Answer |
|---|---|
| define vascular tissues. | |
| what types of plants contain vascular sytems? | vascular plants |
| plants that lack vascular sytems, true roots, stems, leaves and vascular tissue are known as? | nonvascular plants |
| what is another name for a nonvascular plant? | bryophyte |
| how do nonvascular plants transport water and nutrients throughout their bodies? | diffusion and osmosis |
| true or false: nonvascular plants can be found in desserts. | false, they have to live near water or wet areas |
| why are nonvascular plants small? | because of their inability to carry out water or nutrients over large distances |
| how tall are bryophytes? | 1-20 centimeters |
| what 3 groups do bryophytes include? | liverworts, mosses, and hornworts |
| how do rhizoids function in a bryophyte? | they function as roots, anchoring the plant |
| what is the stem of a plant called? | a seta |
| what 2 generations do a bryophyte's life cycle alternate between? | 1) gametophyte generation 2) sporophyte generation |
| gametophyte generation. | is SEXUAL, produces gametes by MITOSIS which fuse to form a zygote that grows into a sporophyte |
| sporophyte generation. | is ASEXUAL, produces spores by MEOISIS that will develop into gametes |
| which is the dominant cycle in a plant's life? | gametophyte generation |
| how many species of vascular plants have been identified? | more than 250,000 |
| what is another name for a vascular plant? | tracheophytes |
| why are vascular plants more well supported and more rigid than nonvascular plants? | because vascular plants have the presence of ligin |
| define ligin. | a waxy substance present in only vascular plants' cell walls |
| what 3 things do vascular plants have in common with nonvascular plants? | they both have cuticles, stomata, and guard cells |
| define cuticles. | |
| define stomata. | |
| define guard cells. | |
| vascular tissue includes: | xylem and phloem |
| define xylem. | |
| define phloem. | |
| what are the 2 largest categories of vascular plants? | seedless and seeded |
| define seed. | an embryo plant surrounded by an endospore, source of nutrition for a developing plant, and 1 or more protective seed coats |
| how do seedless vascular plants reproduce? | by spores |
| what is the dominant generation in a seedless vascular plant? | sporophyte generation |
| what are the 4 basic groups of vascular plants? | whisk ferns, horsetails, club mosses, & ferns |
| whisk ferns. | the simplest of the vascular plants |
| horsetails. | has 15 species, has hollow stems, with ribs giving them a coarse texture |
| club mosses. | called this because they produce spores on narrow, club-like cones |
| ferns. | largest group; has around 12,000 species, greatly varying in sizes (3mm - 28m) |
| what type of seedless vascular plants would pioneers use to clean dirty pots and pans? | horsetails |
| what is the largest group of vascular seedless plants? | ferns |
| how do seed bearing vascular plants reproduce? | by producing seeds |
| how does reproduction by seeds increase the plant's adaptibility? | 1) allowing plants to survive harsh environmental conditions 2) allowing plants to spread to new areas via seed disposal |
| what are the 4 parts of a seed? | embryo, cotyledons, seed coat, & endosperm |
| embryo. | partially developed plant, capable of growing into a mature plant |
| cotyledons. | 1 or 2 embryonic leaves; may develop into mature leaves or may nourish plant during growth |
| seed coat. | hard covering around the embryo |
