Part 1—The Botany Series: Introduction (04:08)

FREE PREVIEW

This program will explore plant species, structure, life patterns, and interaction. There are approximately 260,000 species divided into vascular and non-vascular sub-kingdoms. Algae and land plants share important characteristics; see a gas exchange experiment.

Non-Vascular Plants (03:53)

Plants adapted to land by producing lignin. Land plants are divided into vascular and non-vascular categories. Non-vascular plants are further divided into three classes. Moss is the most numerous class of bryophytes; they reproduce sexually and asexually.

Vascular Plants (05:10)

Tracheophytes comprise over 240,000 species and are classified into seedless, gymnosperms, and angiosperms. Other divisions of gymnosperms include cycads, gnetales, and ginkgoes. Angiosperms are classified as monocots or dicots; grasses are the most successful angiosperms.

Structure and Growth of Seed Plants (02:59)

Plant cells divide in specific areas, meristems; apical meristems produce the most rapid growth. Cells differentiate into three kinds of tissue: epidermis, vascular tissue, and ground tissue. See a transport experiment.

Roots (04:39)

Seedlings sprout roots below ground before it is visible above ground; learn the function of plant roots. The two types of root systems are tap roots and fibrous roots. Most roots contain three tissue layers. See a demonstration of how root hairs work.

Soil (02:10)

All the soil on Earth was once rock; erosion resulted in the formation of soil. Over time, the decaying of plants and animals established top soil. Basic soil includes large particle and small particle soil.

Stems (04:30)

Stems consist of the same tissue as roots. There are two main types of stalks. Herbaceous shoots are soft, fleshy and produce no secondary growths, while woody ones help the plant grow taller.

Leaves (04:02)

Greeneries absorb sunlight. Plants produce food derived from sunlight in the leaves. Shrubs are made up of three tissue types.

Description

This video discusses types of plants, differentiates between vascular and non-vascular plants, lists adaptations for living on land, and looks at the function of roots and leaves. It also examines the classes of bryophytes and considers the effects of clay and sand in soil on plants.
