NEET Biology question
Identify the characters with reference to the plant in which eight nucleated embryo sac was first studied by strasburger. I – Micropyle, chalaza and funiculus are arranged in the same vertical line In the ovule. II – presence of both unisexual and bisexual flowers in the same plant. III – Filiform apparatus helps in conduction of food materials from Endosperm to egg apparatus. IV – Long funiculus coils like a watch spring around the ovule.
