Which phyla have phloem sieve elements Bryophyta Monilophyta
Solution
Please find the answers below:
Part 32: Choice 4 (Anthophyta, or modern day plants or angiosperms are the most advanced nature of plants which contain complex vascular tissues. They have separate conducting tissues for water and food. Their sieve tubes contain companion cells and other accessory cells as well.)
Part 33: Choice 4 (As described above, anthophytes represent the modern day flowering plants or angiosperms. They contain a true stem which gets lignified with time and becomes hard. Although weak and tender stems are also visible and present in ferns and other lower plants, a true hard lignified stem is found in conifers and angiosperms only)
Part 34: Choice 4 (The lower plants like bryophytes, pteridophytes etc do not contain true vascular tissues. They are also devoid of any stomatal openings and guard cells. True stomata and guard cells appeared in the flowering plants with diverse functions. Though some conifers also contain stomata but generally, their stomatal openings are minimized to prevent evaporation of water.)
