New plant organs are formed throughout the life of a plant by clusters of embryonic cells known as meristem. given this
information, which of the following must be true about plant development?
a.
plants develop only during times of complete dormancy.
b.
plant development continues throughout the life of a plant.
c.
plants do not develop because their cells are unable to differentiate.
d. plant development stops when a plant reaches maturity.

The correct option is B) Plant development continues throughout the life of a plant.

Explanation:

In plants, growth is considered to be continuous. Meristems ca be described as the embryonic cells in plants by which new organs of the plant are formed throughout their life. Meristems are undifferentiated cells which have the ability to develop into different plant organs. Hence, option B is correct.

Other options like option C is not correct because the plans do develop and their cells are able to differentiate.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
