Question

Which of the following is correct in a plant cell?
(a)Bigger vacuole with rigid cell wall
(b)Centriole takes part in cell division
(c)Centrosome are inactive in n non-dividing cell
(d)Absence of cell membrane

Answer 1

Cells are the functional and structural unit of living things that acts as building blocks and human beings composed of trillions of cells that provide structure to the body. They take nutrients from the food and convert them into energy to carry out various functions. Some parts of cells consist of organisms to perform a specific task within the cell.

Complete answer:
Plant cell constitutes a large central sap which is the vacuole. Matured plant cells consist of large vacuole which occupies 30% of the volume of the cell and can occupy 80% of the volume in certain cell types and conditions. Plant cells are much bigger than the animal cell and are typically rectangular or cube in shape which have structural organelles that are not found in animal cells such as a cell wall, vacuoles and plastids like chloroplast whereas animal cell consists of cilia, flagella, lysosomes, and centrioles which are not found in the plant cell. They constitute cellulose, plastids, pectin, and hemicellulose that are important for photosynthesis and storage of starch and various large vacuoles that are responsible for the regulation of turgor pressure in the cell.

Additional Information: Plant cell consists of the organelles which are responsible for producing hormones and enzymes to provide energy to the plant cell. The DNA in the plant cell helps in making new cells that enhance the growth of the plant and it is enclosed within the nucleus which is a membranous structure at the center of the cell. Plant cell constitutes cell organelles which include cell wall, cell membrane, chloroplast, plasmodesmata, cytoskeleton, vacuoles, Golgi bodies, ribosomes, mitochondria, endoplasmic reticulum, nucleolus, nucleus, and peroxisomes. The cell wall is present in the plant cell which is the richest outer covering of the plant cell and helps in protecting the plant and gives its shape. It is made up of two layers which include a middle lamella and a primary cell wall. Middle lamella helps in strengthening the layer and the primary cell wall is made up of cellulose which helps in dividing and maturing.

So, the correct answer is 'Bigger vacuole with a rigid cell wall'.

Note: Plants have definite shapes due to the rigid cell wall which takes in a lot of water and helps them in retaining their shape. chloroplast helps in the manufacturing of the food through photosynthesis and which helps in the storage for the waste of the plant cell. Sun's 16 energy is used by the plants and the remaining goes to the human beings and animals in the form of carbohydrates and sugar.
