Question

Prepare a model of a plant cell or an animal cell.

Answer 1

Hint: Plant cell and animal cell both are eukaryotic cells consisting of membrane-bound organelles, but there is some difference between plant cell and animal cell on the basis of their function.

Complete Answer:
The plant cell is larger compared to the animal cell. The cell wall of the plant is made up of polysaccharide and cellulose. The cell wall is differentiated into a primary wall, secondary wall, and middle lamella. Primary wall is a first formed wall made up of thin, elastic, and extensible cells which consist of loose cellulose microfibrils embedded in the amorphous gel-like matrix. Secondary wall form after maturation of primary wall which consists of compactly arranged microfibrils. Secondary wall also consists of lignin and suberin. Middle lamella is the connecting layer between two cells which form just after cytokinesis consisting of calcium and magnesium pectate. The cell wall of the plant consists of small pores and pits which function for transportation of substance from one cell to another.

Additional information:
The cell membrane is the outermost covering of cell protoplast which is inner to the cell wall. The cell membrane is made up of lipid bilayer which protects the cell from injury and also allows the flow of material from cell to cell through plasmodesmata.
The cytoplasm is a jelly like a fluid component of protoplasm consisting of all cell organelles except nucleus. The cytoplasm consists of a cytoplasmic matrix which is transparent and homogenous. Minerals, sugars, amino acids, nucleotides, vitamins, proteins and enzymes present inside the matrix. The cytoplasm of the cell shows cytoplasmic streaming which helps in transportation of substance between cell organelle.
Mitochondria is the double membrane-bound organelle consisting of its DNA. Mitochondria exist in both active and inactive states, the active state helps in the respiration process with the production of ATP whereas inactive state slows down the respiration process.
Plastid is a double membrane-bound consisting of its DNA. Plastids are differentiated into leucoplast, chromoplast and chloroplast. leucoplast is colourless plastid which stores starch in amyloplast, fat in elaioplast and protein in aleuroplast. Chromoplast is coloured plastid which provides colour to fruits and flowers whereas chloroplast is green colour plastid helps in photosynthesis.
Endoplasmic reticulum doest present alone inside the cell, it forms a connection between the nuclear envelope and the Golgi complex. It is present in two forms one smooth and one rough. Smooth endoplasmic reticulum synthesise and store fat whereas rough endoplasmic reticulum synthesises and stores protein. Endoplasmic reticulum helps in rapid intracellular transport of material from Golgi bodies to other cell organelles.
Golgi apparatus is a flat, expanded structure with intercommunicating cisternae. In-plant cell Golgi complex consists of unconnected unit dictyosomes. Dictyosome synthesises the pectic compound of the middle lamella and polysaccharide of the cell wall.
The ribosome is a small spherical organelle without any membrane. Ribosome helps in protein synthesis and it is of 80S type in all
eukaryote.
The vacuole is membrane-bound vesicles. Vacuole consists of fluid fill sap which consists of minerals, sugars, amino acids and protein. In the young plant, small size vacuole is present which aggregate and form large vacuole in the mature plant.
The nucleus is the main cell organelle of all cells which consist of genetic information. It is double membrane-bound consisting of nucleoplasm, nuclear matrix and chromosome. The genetic information in the nucleus helps in growth, development and reproduction. It forms ribosome which helps in protein synthesis. The plant cell model is given below:

Note: In-plant cell nucleus is present near to the corner side due to the presence of large vacuole in the centre. The activity of lysosome is also controlled by vacuole that's why lysosome is rarely found in a plant cell.
