Question

Give the functions of the following:

1. Nucleus 4. Cell Membrane

2. Plastids 5. Pseudopodia

3. Genes​

Answer 1

Answer:

1. The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume

2. Plastids are the site of manufacture and storage of important chemical compounds used by the cells of autotrophic eukaryotes. They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color.

3. Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.

4. The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit

5. The functions of pseudopodia include locomotion and ingestion: Pseudopodia are critical in sensing targets which can then be engulfed; the engulfing pseudopodia are called phagocytosis pseudopodia. A common example of this type of amoeboid cell is the macrophage.

Answer 2

1 ) Nucleas :- The nucleus is a double membrane organell found in all eukaryotic Cell . It is the largest organell . Nucleus is dark , round or oval shaped structure . It is also present near the centre of the cell . It was discovered by Robert Brown in 1831 .

Nucleus consist of four parts :-

1 ) Nuclear Membrane

2 ) Nucleolus

3 ) Nucleoplasm

4 ) Chromatin Material

Function :- 1 ) It control the all activities of the cell .

2 ) It contain DNA and other components C they transmitted heridiatery character generati upon to generation .

3 ) Control the synthesis of the enzymes involved in cellular metabolism .

2 ) Cell Membrane :- The outermost covering of the cell , that separate contents of the cell from surrounding environment. Cell Membrane are also as Plasma membrane. Cell Membrane is made up of Lipid and Protien .....

Function :- Cell Membrane are selectively permeable membrane . because it allow entry and exit of some material in and out of the cell . It also prevent movements of some other materials therefore is called a selectively permeable membrane.....

3 ) Plastid :- These organelles are found only in plant cell . It is bounded by double membrane these are green in colour due to the presence of chlorophyll .

4 ) Pseudophia :- The function of pseudophia include locomotion and ingestion are critical in sensing targets which can then be engulfed , the engulfing Pseudophia are called phagocytosis Pseudophia . A common example of this type of emoibod cell is the macrophage .

5 ) Genes :- The genes are a set of a instruction that determine what the organisms is like . it's appearance , how it's survive , and how it behave in it's environment .
