Chapter 13 - Evolution in Plants and Fungi
The Diversity of Plants. The University of Wisconsin has prepared a fine set of images for plants, plant biology, and plant structures. As one example, follow the links from the home page to “Links to Image Sets” to “General Botany” to “Cells and Tissues” to “Curcubita Stem”. Select taxa that may interest you and call up their images.

The transfer of pollen from male to female plant parts is an essential step in the biology of plants. Pollination is often cited as an example of co-evolution between plants and animals. Are all flowering plants pollinated by bees? Indeed, not, although bees are certainly important. What adaptations do the stapeliad flowers have for pollination, what insects have they evolved to attract, and what brings the insect to the flower?

Plants have cells which are constructed for gathering light, storing carbohydrates as starch, and saving water – in addition to other cellular functions. Do plant cells have organelles? Are there mitochondria, chloroplasts, nuclei, or endoplasmic reticulum? How are plant cells organized to facilitate biochemical reactions that plants use?
