Description
The transport system in plants is just as important for survival as it is in animals. In this program, take a look at how multicellular plants obtain and distribute nutrients. Learn about the process of photosynthesis and watch simple diagrams on how the process works. Botanist David Cantril and Horticulturalist Richard Rowe provide an up-close look at xylem and phloem to reveal what is going on inside plants.

What are these alien life forms living among us? They're.plants! This video investigates the major differences-and some striking similarities-between plants and animals in the areas of what they consume, how they breathe, and how they reproduce. Plant evolution, cell structure, the photosynthesis/respiration cycle, flowering and non-flowering plants, and sexual and asexual reproduction are covered. Correlates to National Academy of Sciences National...

Description
Forests are not just collections of growing trees. A forest is a complex environment, home to thousands of intricately interconnected living species. This program explores three aspects of the forest: the amazing process of photosynthesis, by which plants collect solar energy and convert it into essential compounds; the role of forests in global weather and in maintaining the balance of the biosphere; and the threats to our forests.

This program explores the basic structure of both animal and plant cells and the specific functions that different cell components serve. After an overview of a complete cell, individual segments dive in to detail each of the specific parts. Discrete, pedagogical segments cover: the plasma membrane, extracellular matrix, flagellum and cilia, the nucleus, nucleolus, nuclear envelope, cytosol and cytoplasm, the rough and smooth endoplasmic reticula,...

"Decades of research document plants' impressive abilities: they communicate with one another, manipulate other species, and move in sophisticated ways. Lesser known, however, is the new evidence that plants may actually be sentient. Although plants may not have brains, their microscopic commerce exposes a system not unlike the neuronal networks running through our own bodies. They can learn and remember, possessing an intelligence that allows them...

From the sponge to the giraffe, from mosses to redwoods, this program examines the similarities and differences between the denizens of the animal and plant kingdoms. Distinctive characteristics of plants and animals, including physical structure, methods of reproduction, and life cycle, as well as where they find their food and how they interact with other organisms are discussed. Vivid images underscore the diversity of the phyla, classes, and species...
