The middle lamella is a layer which cements the primary cell walls of two adjoining plant cells together. ... In a mature plant cell it is the outermost layer of cell wall. In plants, the pectins form a unified and continuous layer between adjacent cells.

Plastids are defined as small organelles present in the cytoplasm of the plant cell. ... Chloroplasts - These kind of plastics are used in the process of photosynthesis as they have green colored pigment.

Answer:

Plastids are an organelle type found in all plants and algae, never in animals, fungi, or prokaryotes . It contains inner and outer membrane , stroma filled with fluid , and it has many, many functions.

Middle Lamella is the outermost layer of the cell. It acts as an adhesive, sticking adjacent plant cells together and gives the plant stability, channels in the cell walls that link adjacent cells together, and allow transport of substances and communication between cells.

Explanation: 

Complete question...

a) the same codons are assigned to the same amino acids in most living things.

b) the same codons are assigned to the same DNA sequences in most living things.

c) None of these are correct.

d) the same amino acids are assigned to the same DNA sequences in most living things.

The genetic code is ubiquitous- it is found everywhere in most living organisms. Thus a) the same codons are assigned to the same amino acids in most living things. 

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

The nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P... life on Earth is Carbon based nucleotides contain 5-carbon sugars, and nitrogen; the bases may contain single to double bond rings

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Codons are three nucleotide bases, with each codon encoding an amino acid or signalling the beginning or end of protein synthesis.

RNA codons determine certain amino acids so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Cysteine and Uracil) Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
