Plants are distributed worldwide in varying numbers. While they inhabit a multitude of biomes and ecoregions‚ few can be found beyond the tundras at the northernmost regions of continental shelves. At the southern extremes‚ plants have adapted tenaciously to the prevailing conditions. (See Antarctic flora.) Plants are often the dominant physical and structural component of habitats where they occur. Many of the Earth’s biomes are named for the type of vegetation because plants are the dominant

KINGDOM PLANTAE Also known as Kingdom Metaphyta Includes all types of eukaryotic‚ multicellular‚ photosynthetic‚ plants found in the biosphere Most are autotrophs (synthesize own food with help of solar energy) Contains about billion types of plant species Based on biologists‚ plants are divided into four main groups: 1. Phylum Bryophyta 2. Phylum Pteridophytae 3. Phylum Angiosperms 4. Phylum Gymnosperms These four main groups were classified based on: The presence/absence of vascular tissues

Synopsis – Grade 9 Science Term II Chapter 1: Atoms and Molecules Law of conservation of mass: Mass can neither be created nor can it be destroyed in a chemical reaction. Law of constant proportion: A chemical substance always contains the same elements in a fixed proportion by mass‚ irrespective of the source of compound. Atom: The smallest particle which is the building block of matter. The symbol of the element is made from one or two letters of the English

For eating kangaroos are autotroph and they have chambered stomachs similar to those of cattle and sheep They regurgitate the vegetation they have eaten‚ chew it as cud ‚ and then swallow it again for final digestion. Because of its grazing‚ kangaroos have developed specialised teeth

Study Guide: Chapters 3 and 4 Answer the following questions—you do not need to answer in complete questions. Differentiate between potential‚ kinetic and low quality energy. Potential- Energy that is stored in an object due to its configuration Kinetic- energy an object possess due to its motion and mass. Low quality- Energy that is unorganized and do little work. How does entropy relate to the continual energy needs of organisms Entropy represents the disorder of a system which allows the
