Date: Thursday, July 30 th 2015 Topic: Classification of Plants without Flower. Objective: To identify the classification of plants without flower. CHARACTERISTICS OF PLANTS WITHOUT FLOWER When we think of growing a plant, we probably imagine planting a seed. Not all plants make seeds. In fact, all nonvascular plants and some vascular plants are seedless. These plants, like all plants, spread by producing spores.
3
All seedless plants are Plants without Flowers. Plants Classification Vascular Plants Seed Gymnosperms Angiosperms Seedless (flowerless) Ferns Horsetails Club Mosses Nonvascular Plants Seedless (flowerless) Moss Liverworts and Hornworts

CHARACTERISTICS OF PLANTS WITHOUT FLOWERS Nonvascular Plants: Mosses Mosses grow on moist soil or on rocks, forming a fuzzy mat of tiny green plants. A rhizoid is a nonvascular rootlike structure that helps mosses attach to surfaces such as rocks and trees. Rhizoids help the plants get water and nutrients.
5
Liverworts and Hornworts Like mosses, liverworts and hornworts are small nonvascular plants that usually live in damp environments.
6
Vascular Plants Ferns Ferns are seedless vascular plants often grown as house plants. Ferns have roots, and most ferns also have rhizomes that help them spread. A rhizome is an underground stem from which new leaves and roots grow.
7
Horsetails Horsetails have can-like stems with leaves that grow in a unique whorl pattern around the stems. They can be up to eight meters tall, but many are smaller.
8
Club Mosses Club Mosses have vascular tissue, roots, stems, and tiny leaves. An example of a modern club moss is the ground pine (a miniature pine tree). They grow in woodlands and near streams and marshes.
