Pollination enables gametes to come together within a flower

Plants derive most of their organic mass from the CO2 of air ? also depend on soil nutrients such as water and minerals ? classic experiments by Jean-Baptiste van Helmont & Stephen Hales ? nitrogen acquired mainly as nitrate ions (NO3?) Copyright ? 2005 Pearson Education, Inc. publishing as Benjamin Cummings Essential Elements ? more than 50 chemical elements found in inorganic substances in plants ? not all of these are essential ? chemical element is considered essential if it is required for a plant to complete a life cycle

Mica Piro Chapter 36: Resource Acquisition & Transport in Vascular Plants Adaptations for acquiring resources were key steps in the evolution of vascular plants (36.1) EVOLUTON Land plants typically inhabit 2 worlds?above ground (where shoots acquire sunlight and CO2) and below ground (where roots acquire water and minerals) The algal ancestors of land plants absorbed water, minerals, and CO2 directly from the water in which they lived Earliest land plants were nonvascular plants that grew photosynthetic shoots above the shallow fresh water in which they lived The leafless shoots had waxy cuticles and few stomata, which allowed them to avoid excessive water loss while still permitting some exchange of CO2 and O2 for photosynthesis

Mica Piro Chapter 35: Plant Structure, Growth, & Development Plants have a hierarchical organization consisting of organs, tissues, and cells (35.1) An organ consists of several types of tissues that together carry out particular functions A tissue is a group of cells, consisting of one or more cell types that together perform a specialized function Vegetative growth (production of leaves, stems, and roots) is only one stage in a plant?s life Most plants undergo growth relating to sexual reproduction In angiosperms, reproductive growth is associated with the production of flowers The 3 Basic Plant Organs: Roots, Stems, and Leaves

Biological Diversity, Animal Behavior & Endangered Species Study Guide 1. What is biodiversity? What is the underlying cause of biodiversity? Biodiversity is a variety of different species in a specific area. The major cause for lowering biodiversity is the loss of habitat due to human kind activities. 2. Biological diversity involves the following concepts. Explain each: Genetic diversity ? variety of genes in a species to allow for it to have an reproductive advantage Habitat/ecosystem diversity- large area with different biomes for organisms to thrive in. Species diversity- number of different species and their abundance.

Chapter 4 Evolution and Biodiversity Summary 1. Life emerged on the earth through two phases of development: a chemical evolution of the organic molecules, biopolymers, and systems of chemical reactions to form the first cells and the biological evolution from single-celled prokaryotic bacteria to single-celled eukaryotic creatures, and then to multicellular organisms. 2. Evolution is the change in a population?s genetic makeup over time. Evolution forces adaptations to changes in environmental conditions in a population. The diversity of life on earth reflects the wide variety of adaptations necessary and suggests that environmental conditions have varied widely over the life of the earth.

Chapter 10 biodiversity hotspots an idea first proposed in 1988 by environmental scientist Norman Myers. These ?ecological arks? are areas especially rich in plant species that are found nowhere else and are in great danger of extinction. deforestation the temporary or permanent removal of large expanses of forest for agriculture, settlements, or other uses. ecological restoration the process of repairing damage caused by humans to the biodiversity and dynamics of natural ecosystems. old-growth forest an uncut or regenerated primary forest that has not been seriously disturbed by human activities or natural disasters for 200 years or more. overgrazing occurs when too many animals graze for too long and exceed the carrying capacity of a rangeland area. pastures
