1. All plants are multicellular, have cell walls made of cellulose, and perform photosynthesis using chlorophyll.
2. Plants provide oxygen through photosynthesis and serve as a primary food source for many organisms; great apes rely on plants for nutrition and habitat.
3. Cell walls provide structural support and protection, while cuticles reduce water loss and protect against pathogens.
4. Plants benefit from being on land by accessing more sunlight and carbon dioxide; challenges include desiccation, UV radiation, and the need for structural support without water buoyancy.
5. Mosses are non-vascular, lack true roots/stems/leaves, and require moist environments; ferns are vascular, have true roots/stems/leaves, and can grow taller and in drier conditions.
6. Vascular plants have specialized tissues (xylem and phloem) for transporting water and nutrients; non-vascular plants lack these tissues and rely on diffusion and osmosis.
Bryophyte: Moss
Pteridophyte: Fern
Gymnosperm: Pine tree
Angiosperm: Flowering plant (e.g., rose or grass)
Parent Tip: Review the logic above to help your child master the concept of vascular vs nonvascular plants worksheet.
