NEET BIOLOGY

Detailed explanation-1: -Solution: Multicellular eukaryotes • Cells bound by cell walls made up of cellulose • Cells possess chloroplasts and show autotrophic mode of nutrition are the unique features of kingdom plantae.

Detailed explanation-2: -Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules.

Detailed explanation-3: -Organisms that possess cell wall in their cellular structure include-bacteria, fungi and plants. Bacterial cell walls are made up of peptidoglycan, plant cell walls are made up of cellulose and the fungal cell walls are made up of chitin.

Detailed explanation-4: -Characteristics of Kingdom Plantae They reproduce asexually by vegetative propagation or sexually. These are multicellular eukaryotes. The plant cell contains the outer cell wall and a large central vacuole. Plants contain photosynthetic pigments called chlorophyll present in the plastids.

Detailed explanation-5: -A plant cell wall’s unique ability to expand without weakening or breaking-a quality required for plant growth-is due to the movement of its cellulose skeleton, according to new research that models the cell wall.
