Question

Which one is a wrong statement?
A. Brown algae have chlorophyll a and c and fucoxanthin
B. Archegonia are found in Bryophytes, Pteridophyta, and Gymnosperms
C. Mucor has biflagellate zoospores
D. Haploid endosperm is a typical feature of gymnosperms

Answer 1

Plants in the Plantae kingdom have various phyla that have different unique features. Some have vascular systems, some are simple, some are complex, some generate seeds while some are seedless. The way from simple to complexity is all evolution which happens with the requirement and time.

Complete answer: Classification is a grouping of organisms based on their characters. So the natural classification means grouping the natural organisms including plants and animals based on their similarities or shared features.
Option A: Brown algae have chlorophyll a and c and fucoxanthin: Brown algae are the multicellular algae that grow in water. They are also called Phaeophyceae. It has fucoxanthin present In them so are called brown algae as it provides it with a brown colour. It also has a and c chlorophyll pigment.
Option B: Archegonia is found in Bryophytes, Pteridophyta and Gymnosperms: Archegonia is a female reproductive structure. It has a neck and swollen base which has an egg. It is a feature of bryophytes, gymnosperms, and pteridophytes.
Option C: Mucor has biflagellate zoospores: Mucor is a member of the fungi kingdom. It belongs to the division Zygomycota. They have sexual spores called zygospores. They lack flagella.
Option D: Haploid endosperm is a typical feature of gymnosperms: Gymnosperms do not do double fertilization. The endosperm is haploid and formed haploid megaspores by repeated division. This will develop into a female gametophyte with haploid chromosomes.
So the answer is option C: Mucor has biflagellate zoospores

Note: Gymnosperms have no outer covering of the seeds. They do not give flowers and fruits. They are the non-flowering plants. Their strong root system is good for soil erosion. They are good sources of fuels like conifers. They are heterosporous and have two types of spores.
