NEET Biology
In the structure of a typical angiosperm flower, the correct arrangement of floral whorls from outermost to innermost is:
A Calyx → Corolla → Androecium → Gynoecium
B Corolla → Calyx → Gynoecium → Androecium
C Androecium → Gynoecium → Calyx → Corolla
D Gynoecium → Androecium → Corolla → Calyx
NEET Biology
During double fertilization in angiosperms, one sperm cell fuses with the egg to form the zygote, while the second sperm cell fuses with:
A The synergids to form the endosperm
B Two polar nuclei to form the primary endosperm nucleus (PEN)
C The antipodal cells to form the embryo
D The nucellus to provide nutrition
NEET Biology
Which of the following is a characteristic feature of angiosperms known as double fertilization?
A Fusion of two gametes from the same parent
B One sperm fuses with the egg and the other with polar nuclei
C Fusion of two polar nuclei before sperm entry
D Two eggs fertilized by two different pollen grains
NEET Biology
Luteinizing hormone (LH) surge in the middle of the menstrual cycle triggers:
A Ovulation
B Menstruation
C Formation of corpus luteum only
D Endometrial thickening
NEET Biology
Which of the following is the correct sequence of stages in prophase I of meiosis?
A Leptotene → Zygotene → Pachytene → Diplotene → Diakinesis
B Zygotene → Leptotene → Pachytene → Diakinesis → Diplotene
C Leptotene → Pachytene → Zygotene → Diplotene → Diakinesis
D Diakinesis → Diplotene → Pachytene → Zygotene → Leptotene
NEET Biology
Which of the following hormones is produced by the corpus luteum after ovulation?
A Estrogen only
B Progesterone only
C Both estrogen and progesterone
D Follicle-stimulating hormone (FSH)
NEET Biology
Double fertilization in flowering plants involves two separate fertilisation events. One event forms the zygote, and the other forms the endosperm. The secondary nucleus that fuses with a sperm cell to form the endosperm is:
A Haploid and derived from the pollen grain
B Diploid, formed by the fusion of two polar nuclei
C Triploid and derived from the synergids
D Tetraploid and derived from the antipodal cells
NEET Biology
In a dicot seed, the endosperm is completely consumed during embryonic development, and the cotyledons become the food-storage tissue. Such seeds are called:
A Albuminous (endospermic) seeds
B Dicots cannot have cotyledon storage
C Exalbuminous (non-endospermic) seeds
D Perispermic seeds
