HORTICULTURE

Detailed explanation-1: -In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.

Detailed explanation-2: -All plants are made of cells that have firm cell walls made of a tough polysaccharide called cellulose. This gives plants form and structure. All plants are autotrophs, which means they are all able to directly use the sun’s energy to make their own food through the process of photosynthesis.

Detailed explanation-3: -The kingdom Plantae are eukaryotes that make their food through photosynthesis. Most are multicellular, but some green algae are unicellular. They are autotrophs with cell walls that contain cellulose. Mosses, ferns, and flowering plants are examples.

Detailed explanation-4: -The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited.

Detailed explanation-5: -Kingdom Plantae includes autotrophic organisms with cellulosic cell wall while kingdom Animalia includes heterotrophic organisms without the cell wall.
