Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Watching plants grow is like watching paint dry: It happens so slowly that the changes are imperceptible from one moment to the next -- and yet the end results are dramatic. This video segment shows just how amazing plant development can be by depicting various phases of the process using time-lapse photography.

Customizable and printable flower parts flash cards. You can customize the card size, color, border, and content. Terms included in this card set are stamen, anther, filament, carpel, stigma, style, ovary, sepal, ovule, and petal. These cards are great for studying plant morphology.
The purpose of this resource is to observe the flowering and leaf stages of selected garden plants throughout the year. After a phenological garden is planted, students observe the growth of leaves and blooming of flowers on the plants. These plants were selected because each plant blooms at a different time in the year.

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of moisture to the atmosphere by plants.
Students gain an understanding of the parts of a plant, plant types and how they produce their own food from sunlight through photosynthesis. They also learn about transpiration, the process by which plants release moisture to the atmosphere. With this understanding, students test the effects of photosynthesis and transpiration by growing a plant from seed. They learn how plants play an important part in maintaining a balanced environment in which the living organisms of the Earth survive. This lesson is part of a series of six lessons in which students use their evolving understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
An interactive lesson plan that entails reading the book, "A Fruit is a Suitcase for Seeds, and the planting of a fruit and a flower as a learning comparison. By the end of the lesson students should be able to understand what seeds are and that if two objects have a seed than they are most likely related; such as fruit and flowers.
