Answer:
stores extra food
is responsible for photosynthesis
supports the plant
makes up the majority of a plant
Explanation:
Ground tissues are one of the three types of plant tissues (others being dermal and vascular). They are composed of cells as follows: parenchyma, collenchyma, and sclerenchyma. These three cells that make up the ground tissues perform different functions in the plant cell.
- Parenchyma functions in photosynthesis and storage of extra food (carbohydrates) in the cell.
- Collenchyma functions in the support of young regions of the plant
- Sclerenchyma, which has the thickest cell wall, functions mainly in the strengthening/support of the plant cell.
Also, among the three tissue types in a plant, ground tissues make up majority of the plant cell.
The original codons code for Leucine and Glutamic acid. The mutated codons code for Valine and Glutamine.
<h3>Genetic codes and amino acids</h3>
Each of the genetic codes. otherwise known as codons, translates to an amino acid.
Following the table of genetic codes with their respective amino acids:
- CTC (CUC) codes for Leucine
- GAG codes for Glutamic acid
- GTC (GUC)codes for Valine
- CAG codes for Glutamine
Thus, the glutamic acid in the original codon has been replaced with glutamine in the mutated codon while Leucine has been replaced with Valine.

Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
Answer:
Your body has different kinds of cells. Though they might look different under a microscope, most cells have chemical and structural features in common. In humans there are about 200 different types of cells and within this cells there are about 20 different types of structures or organelles.
