- What adaptation do seed plants have in addition to the seed that is not found in seedless plants?a. gametophytesb. vascular tissuec. pollend. chlorophyllarrow_forwardWhich of these pairs is mismatched? a. anther—produces microspores b. carpel—produces pollen c. ovule—becomes seed d. ovary—becomes fruit e. flower—is a reproductive structurearrow_forwardOn what are plant embryos dependent? Select one: a. Water for pollination b. Nutrients provided by the sporophyte c. Water for fertilization d. Nutrients provided by the gametophytearrow_forward
- Which suite of reproductive features distinguishes angiosperms from gymnosperms? A. The carpel, double fertilisation, endosperm formation B. Pollen-formation, double fertilisation, seed-formation C. Pollen-formation, the carpel, double fertilisation, endosperm formation D. The carpel, double fertilisation, endosperm formation, seed-formationarrow_forwardFruits do not form in gymnosperms becausea. in gymnosperms, the seed is surrounded by the ovule.b. in angiosperms, the ovary is surrounded by the ovule.c. in gymnosperms, the ovule is surrounded by the ovary.d. in angiosperms, the ovule is surrounded by the ovary.arrow_forwardHow are compound leaves distinguished from simple leaves?a. Compound leaves do not have axillary buds at the baseof leaflets.b. Compound leaves are smaller than simple leaves.c. Simple leaves are usually deciduous.d. Compound leaves are found only on pine trees.e. Simple leaves are found only in gymnosperms.arrow_forward
- From what structure does a pollen grain develop? A. Egg B. Embryo C. Endosperm D. Microsporearrow_forwardBesides the seed, what other major structure diminishes a plant’s reliance on water for reproduction? a. flower b. fruit c. pollen d. sporearrow_forwardWhich of these is a feature not present in seedless plants that have contributed to the success of seed plants on land? a. Seeds have four layers of protective tissue, the seed coat, that improve survival by providing more protection from environmental stresses. b. The reduced gametophytes of seed plants are nurtured by sporophytes and protected from stress, such as drought conditions and UV radiation. c. Seed germination is solely mediated by water during episodes of heavy rain. d. Pollen grains, with walls containing sporopollenin, deter herbivores. Three unknown non-vascular plant species were collected by Biology 3 students. Which characters BEST discriminate them from one another? 1. protonema II. special organelles III. seta IV. calyptra V. capsule VI. stalk a. I,II,III b. I,III,V c. III, IV, V d. II,IV,VIarrow_forward

The embryo–suspensor axis would be reversed. b. The embryo–suspensor axis would be duplicated. c. The root–shoot axis would be reversed. d. The root–shoot axis would be duplicated.arrow_forwardWhat similar features do gymnosperms and angiosperms possess thatdiffer from other modern vascular plants?a. Gymnosperms and angiosperms both produce flagellatesperm.b. Gymnosperms and angiosperms both produce flowers.c. Gymnosperms and angiosperms both produce tracheids, but notvessels, in their vascular tissues.d. Gymnosperms and angiosperms both produce fruits.e. none of the abovearrow_forward
