The Plant Kingdom Plants are multicellular organisms. Plants have tissues and organs. Their cells have cell walls.
The Plant Kingdom The Plant Kingdom is divided into 2 groups. Vascular: Plants have tissue that acts like tubes. Nonvascular: Plants absorb water much like a sponge soaks up a liquid.
Vascular Plants The vascular plant system provides support and allows plants to grow very tall. Most vascular plants are in the forest.
Nonvascular Plants Nonvascular plants cannot live in dry areas. They must live near a water source. The lack of a transport system prevents nonvascular plants from growing tall.
Gymnosperms Gymnosperms start as a seed, then develops into a seedling, then a tree. The tree drops a cone and the process starts all over again.
Plant Adaptation Cactus plants are adapted to hot, dry climates. Their thick stems hold water and have a waxy coating that helps protect them from drying out.
Seed Plants Some vascular plants have seeds and are gymnosperms and angiosperms. Mangrove Trees and a Barrel Cactus are examples of seed plants.
Gymnosperms and angiosperms produce pollen. The pollen on the plants attaches to bees legs. When the bees visit other flowers, the pollen falls off the bees legs onto the flower. Bees transfer pollen from flower to flower.
