Adapting to Land Chapter 28 Section 1 Overview of Plants Chapter 28 Adapting to Land Three adaptations have allowed plants to be successful on land: a waxy cuticle to prevent water loss haploid spores and diploid seeds to protect reproductive cells special vascular tissues called xylem and phloem for absorbing and transporting materials within the plant.

Classifying Plants Chapter 28 Section 1 Overview of Plants Chapter 28 Classifying Plants Nonvascular plants have neither true vascular tissue nor roots, stems, or leaves. Most vascular plants have vascular tissue and true roots, stems, and leaves. Vascular plants can be further divided into two groups, seedless plants and seed plants. Seed plants include gymnosperms and angiosperms.

Alternating Life Cycles Section 1 Overview of Plants Chapter 28 Alternating Life Cycles All plants have a life cycle known as alternation of generations. In alternation of generations, a haploid (only one of each chromosome) gametophyte produces gametes. Gametes unite and give rise to a diploid (two of each chromosome) sporophyte. The sporophyte produces haploid spores, which develop into gametophytes.

Characteristics of Bryophytes Section 2 Nonvascular Plants Chapter 28 Characteristics of Bryophytes Nonvascular plants are called bryophytes. These plants do not have true roots, stems, or leaves. They are very small and are usually found in moist areas.

Seedless Vascular Plants Section 3 Vascular Plants Chapter 28 Seedless Vascular Plants Vascular plants have several adaptive advantages over nonvascular plants, tissues that move water and food, the ability to live in many environments, and strong stems that allow them to grow tall and receive more sunlight.

Vascular Seed Plants Chapter 28 Section 3 Vascular Plants Chapter 28 Vascular Seed Plants There are two main groups of seed-bearing vascular plants, gymnosperms and angiosperms. Gymnosperms are characterized by naked seeds and no flowers. Angiosperms have flowers and seeds enclosed by a fruit.

Parts of a Flower Chapter 30 Section 2 Sexual Reproduction in Flowering Plants Chapter 30 Parts of a Flower The male reproductive structures are stamens, each of which consists of an anther and a filament. The anther produces pollen grains. The filament supports an anther. The female reproductive structures are called carpels. One or more carpels fused together to make the pistil. The base of a pistil contains the ovary, which will produce A style, which is usually stalklike, rises from the ovary. The tip of the style is called the stigma, which usually is sticky or has hairs in order to trap pollen grains.

Section 2 Sexual Reproduction in Flowering Plants Chapter 30 Pollination Bright petals and distinctive odors attract animals that feed on pollen and nectar, a nourishing solution of sugars. Many different kinds of animals can be pollinators. When these animals gather nectar, pollen sticks to their bodies. As they collect more nectar, the animals deposit some of the pollen on other flowers. This is how the animals pollinate other flowers.
