Which sentence describes the distinction between algae and plants? algae and plants are both eukaryotes that photosynthesize their own food. however, there are important distinctions between these two groups that cause scientists to distinguish between them. algae are unicellular, while plants are multicellular. algae use pigments other than chlorophyll in photosynthesis, while plants only use chlorophyll to photosynthesize food. algae lack the cellular complexity to possess true leaves, stems, and roots that are present in all plants. algal cells have a cell wall made of chitin, while plant cell walls are made of cellulose.

Correct D). Algal cells have a cell wall made of chitin, while plant cell walls are made of cellulose.

Algae and plants are similar as both of them produce their own food by the process of photosynthesis. The main difference is found in their complexity.

The cell wall of the plants is made of cellulose, hemicellulose and pectin, and polysaccharides, while the cell wall of algae is made up of chitin, which is a polysaccharide derived from glucose.

The answer for this is:

D. Algal cells have a cell wall made of chitin, while plant cell walls are made of cellulose.

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.
