Which vascular tissue is involved in the transportation of starch found in fruit pulp? a. xylem b. phloem c. pith

The correct answer will be option B (Phloem).

Explanation:

Phloem is the vascular tissue in plants made of living cells joined end to end which transport organic products from the leaves to other parts of the plants.

In fruits, the food is stored in the form of starch, when starch is needed it is converted to simple sugars and transported via phloem.

In phloem, products enter the phloem by pressure flow mechanism through sieve tube elements and then move along concentration gradient that is from high concentration to low concentration in both upward and downward directions.

Thus, option B is the correct answer.

.

is responsible for the translocation of the nutrients like carbohydrates and amino acids from the leaves to other areas of the plants.

Phloem consists of sieve tubes and companion cells. Sieve tubes are living cells which contain cytoplasm but do not have a nucleus. So its function is supported by a companion cell. The phloem vessel in the vascular bundle will transport sucrose and amino acids away from the leaf. As the vascular bundles are connected with similar structures in the roots, each sieve tube is continuous with those in the roots. Sucrose and amino acids enters the phloem by active transport. Later, it is translocated from the sources to the sinks.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring 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.

    elongation: in which 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.

    termination: in which 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.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
