Explanation:
Answer:
Enzyme
Explanation:
Enzymes are the bio-catalyst that serve to accelerate the metabolic reactions occurring in a living cell. All the metabolic reactions of organisms are catalyzed by enzymes. Each metabolic reaction is catalyzed by specific enzyme. Absence of that particular enzyme leads to absence of the respective product. Since genes code for protein which regulate the specific trait, absence of enzyme does not allow the expression of that trait.
Example: Absence of enzymes for chlorophyll synthesis would lead to absence of chlorophyll from leaves of the green plants.
Two examples of how the biosphere supports life is by reducing the amount of harmful radiation to reach the surface of the earth. It also gives oxygen for animals to breathe
Answer:
Summary
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.
Prokaryotic cells lack a nucleus and membrane-bound structures.
Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
Explanation:
Eukaryotic Cells
Eukaryotic cells usually have multiple chromosomes, composed of DNA and protein. Some eukaryotic species have just a few chromosomes, others have close to 100 or more. These chromosomes are protected within the nucleus. In addition to a nucleus, eukaryotic cells include other membrane-bound structures called organelles. Organelles allow eukaryotic cells to be more specialized than prokaryotic cells. below are the organelles of eukaryotic cells , including the mitochondria, endoplasmic reticulum, and Golgi apparatus.
Prokaryotic cells are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. In prokaryotic cells, the DNA, or genetic material, forms a single large circle that coils up on itself. The DNA is located in the main part of the cell.
