Chapter 7 Lesson 2 Notes

Dr. Wright’s 5th Grade Science Classes

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 bee’s legs. When the bees visit other flowers, the pollen falls off the bee’s legs onto the flower.

• Bee’s transfer pollen from flower to flower.
