Q. Consider the following statement about plants I. Kingdom-Plantae includes eukaryotic autotrophic, chlorophyll containing organisms II. It includes algae, bryophytes, pteridophytes, gymnosperms but not angiosperms III. Plants shows alternation of generation [between haploid gametophytic ($n$) phase and diploid sporophytic ($2n$) phase] Which of the statements given above are correct?
A) I and II
B) I and III
C) II and III
D) I, II and III
Explanation
The plant cell have an eukaryotic structure with prominent chloroplast. Chloroplast contains chlorophyll which is responsible for the plant’s green colour and imparts the ability to absorb energy from sunlight. This energy is used to convert water plus atmospheric carbon dioxide into metabolisable sugars by the biochemical process of photosynthesis. Kingdom includes algae, bryophytes, pteridophytes, gymnosperms and angiosperms. Life cycle consists of alternating haploid gametophyte and diploid sporophyte generations
