Structure and function of eukaryotic cell

Eukaryotes have following promint components of cell

1. True nucleus:
The nucleus is surrounded by a true membrane called nucleoplasm. Nucleus contain hereditary materials, DNA which control inheritance. It also contain RNA synthesize in nucleolus.

2. Cell wall:
It is present only in plant cell, and contain cellulose, hemicellulose, lignin, suberin etc. It provides mechanical support to plants.

3. Cell membrane:
It is present both in plants and animal cells. It is made from protein, lipids and carbohydrates. It acts as selective permeable membrane and control the movement of molecules in and out of the cell.

4. Mitochondria and chloroplast:
Chloroplast is present only in plant cell. It contains chlorophyll which aid in photosynthesis and prepare glucose.
Mitochondria is present in all eukaryotic cells.cellular respiration occurs in mitochondria and ATP is formed by the break down of glucose.

5. Endoplasmic reticulum and Golgi apparatus:
Endomembrane system of eukaryotic cell is made from a network of tube and sacks connected together forming endoplasmic reticulum and golgi apparatus independently. Endoplasmic reticulum may have attached ribosomes or not and is involved in protein synthesis, while golgi apparatus help in modification, packaging, and transport of proteins through out the cell.
Lysosomes, cytoskeleton, vacoules, peroxisomes, glyoxisomes and other organelles are also present in eukaryotic cell.

Answer from: Quest

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

Giraffes with short necks tend to be unable to access enough food, while giraffes with long necks can reach more food at the tops of trees. this causes an advantage for giraffes with long necks. how would you explain this? a. this is an example of a stabilizing selection in which the intermediate form of a trait is advantageous compared to the extreme forms of the trait. b. this is an example of a disruptive selection in which the population of cacti is divided and well-defined. c. this is an example of directional selection in which one end of the bell curve is better adapted to its environment than the other end. d. this is an example of bidirectional selection in which evolutionary pressures from multiple sources encourage an organism to adapt
