9 ) Examine evidence to support an argument that the internal and external structures of plants (e.g., thorns, leaves, stems, roots, colored petals, xylem, phloem) and animals (e.g., heart, stomach, lung, brain, skin) function to support survival, growth, behavior, and reproduction.

10 ) Use evidence and scientific reasoning to explain how characteristic animal behaviors (e.g., building nests to protect young from cold, herding to protect young from predators, attracting mates for breeding by producing special sounds and displaying colorful plumage, transferring pollen or seeds to create conditions for seed germination and growth) and specialized plant structures (e.g., flower brightness, nectar, and odor attracting birds that transfer pollen; hard outer shells on seeds providing protection prior to germination) affect the probability of successful reproduction of both animals and plants.

Gymnosperms are the oldest seed-bearing plants. There are four types of gymnosperms: gnetophytes, cycads, conifers, and ginkgos. Learn about gymnosperms’ distinctive appearance and unique life cycle here.

The classroom resource provides a video that will describe the function of seeds in seed-bearing plants. After utilizing this resources, the students can complete the short test to assess their understanding.

Flowering plants have many parts that are required for reproduction. These parts, including the stamen, pistil, and ovary, work together to make seeds through the process of fertilization.

The classroom resource provides a video that will describe the process of reproduction in flowering plants. After utilizing this resource, the students can complete the short test to assess their understanding.

Plants produce seeds in order to reproduce. Gymnosperm seeds develop in cones, and angiosperm seeds develop in fruit. When a seed is fertilized, in the right conditions, it will germinate, starting the life of a new plant!

The classroom resource provides a video that will describe the process of reproduction in plants with seeds. After utilizing this resource, the students can complete the short test to assess their understanding.

Angiosperm plants reproduce by producing seeds inside a flower. There are two kinds of angiosperms: monocotyledons and dicotyledons.

The classroom resource provides a video that will describe the process of reproduction of flowering plants. After utilizing this resource, the students can complete the short test to assess their understanding.

Plants that reproduce without seeds use several different methods, like budding, plant runners, and spores.

This resource presents a short slide show about the process of reproduction in plants that do not have seeds. After utilizing this resource, the students can complete the short test to assess their understanding.
