Answer:
Refer to the attached image for correct labeling.
Explanation:
- The diagram is of a plant cell and its organelles.
- The nucleus houses the genetic material and controls all life processes.
- A plant cell contains one large vacuole in the center that stores water and nutrients.
- Chloroplast is the site for photosynthesis. It captures light and utilizes it and carbondioxide to produce glucose.
- Mitochondria are called the power house of the cell. Through a process called cellular respiration, they break down the glucose produced in photosynthesis into energy compounds such as ATP as well as oxygen and water.
- The endoplasmic reticulum is the site for protein sysnthesis. It contains two parts: the rough endoplasmic reticulum (RER) which contains ribosomes that synthesize proteins and the smooth endoplasmic reticulum (SER) which packages the proteins into transport vesicles.
- The nucleus contains the nucleolus that is the site for ribosome assembly.
- The cell membrane is a semi-permeable membrane that covers the cell and controls cellular transport.
- The cell wall is a hard, outer covering that protects the cell and maintains its structure and shape.
Answer:
A DNA sequence codes for the same proteins in different species
Explanation:
All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL
The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.
Correct matches of terms and its descriptions:
1. Cloning (most controversial method of genetic engineering)
2. hybridization ( breeding organisms because of beneficial traits)
3. recombinant ( DNA DNA from different biological sources that have been combined and culture)
4. selective breeding ( breeding two different species to make a new individual)
Selective breeding is also called artificial selection. Hybridization.is mating organisms of different species to create a hybrid. Cloning produces similar copy of genetically identical individuals.
<h2>Functions of plasmodesmata</h2>
Explanation:
- They allow the movement of cells to cells for cytoplasmic connection between different cells
- Plant cells, encompassed as they are by cell dividers, don't get in touch with each other through wide stretches of plasma film the manner in which creature cells can. Be that as it may, they do have particular intersections called plasmodesmata (solitary, plasmodesma), places where a gap is punched in the phone divider to permit direct cytoplasmic trade between two cells.
- Plasmodesmata are fixed with plasma film that is consistent with the layers of the two cells. Each plasmodesma has a string of cytoplasm stretching out through it, containing a much more slender string of endoplasmic reticulum.
- Particles beneath a specific size (the size rejection limit) move unreservedly through the plasmodesmal channel by latent dissemination. The size avoidance limit changes among plants, and even among cell types inside a plant. Plasmodesmata may specifically enlarge (extend) to permit the section of certain huge atoms, for example, proteins, in spite of the fact that this procedure is inadequately comprehended.
