Classification of Plants Plants can be did into flowering plants(plants that bear flowers)and non-flowering plants ( plants that do not bear flowers) Flowering and  Non Flowering Plants Flowering plants - form seeds inside fruits that develop from the flowers. Flowering plants can be divided into monocotyledons ( with one cotyledon or seed leaf in the seed) and dicotyledon ( with two cotyledon or two seed leaves). Monocotyledons :( one seed ) MONO - one COTYLEDON - seed -flowers often small and pale, eg. Grass, corn -mainly small with thin trunks, eg. Coconut tree -leaves long and thin with parallel veins, eg. Grass -Seeds with one dicotyledon eg. Corn -Root has many small roots, eg. Onion These are examples of Monocotyledonous plants Dicotyledon  Plants DI - two COTYLEDON - seed - flowers often large and colorful, eg. Rose, flame tree - small, medium or large with very wide trunks, eg. Mahoe -leaves oval, h...

Classification of Animals Animals are classified into two groups vertebrates and invertebrates Vertebrates Vertebrates are animals with backbone. Examples of vertebrates Fish, mammals, reptiles, amphibians, birds Invertebrates Invertebrates are animals without backbone. Coelenterates  - sea anemone annelids – earthworms, leeches echinoderms – starfish, sea urchins, sea cucumbers mollusks – snails, octopi, squid, snails, clams arthropods – insects, spiders, crustaceans such as shrimp, crabs, lobsters Vertebrates FISH The body of the fish is covered in scales and has fins attached to help it move through the water. Fish breathe using gills which take oxygen out of the water. When male and female fish mate, the eggs often meet the sperm in the water. This is called external fertilization. Examples of fish are the herring, Goldfish, Guppy, Northern pike, Wels catfish, Barramundi, Atlantic cod. AMPHIBIANS   The skin of amphibians is very ...

Welcome grade 8T and 8N We have completed  the Respiratory system and now we are look at WATER AND THE EARTH'S ATMOSPHERE  Pages 164-172  in your text book. Please recap the process involved in the Water Cycle shown  below. What is Ground water  The water that settles under ground is called Groundwater. The largest use for groundwater is to irrigate crops. The area where water fills the aquifer is called the saturated zone (or saturation zone). The top of this zone is called the water table. The water table may be located only a foot below the ground’s surface or it can sit hundreds of feet down. Aquifers  are typically made up of gravel, sand, sandstone, or fractured rock, like limestone. Water can move through these materials because they have large connected spaces that make them permeable. The speed at which groundwater flows depends on the size of the spaces in the soil or rock and how well the spaces are connected. ...
