Living and Non-Living things October 14, 2024  Introduction to Living and Non-Living Things Overview of living and non-living things Living things grow, reproduce, and respond to their environment, while non-living things do not. Understanding the differences helps us explore our world. Characteristics of Living Things How to identify Living Things Living things grow, reproduce, respond to stimuli, and require energy. They maintain balance and adapt to their environment over time. Classification of Living Things Categories of Living Organisms Two main groups: plants and animals Further divisions: fungi, bacteria Importance of classification in scienc Identifying Plants and Animals in Jamaica Unique species in Jamaica Common plants found locally Animals native to Jamaica  Survival Needs of Plants and Animals Basic needs for survival Plants need sunlight and water Animals need food and shelter Both need a suitable environment  Designing a Fair Test A fair test ensures that only one variable changes while others remain constant. For example, when testing plant growth, keep sunlight, water, and soil the same, while varying the type of fertilizer used. This way, any differences in growth can be attributed to the fertilizer alone. Constructing a Greenhouse and a Shade House Purpose in Gardening Greenhouses provide warmth and protect plants, while shade houses offer shelter from harsh sunlight. Both support plant growth and extend the growing season. Identifying and Naming Common Plants and Animals in Jamaica Common Plants Common Animals Main Parts of a Plant Roots, Stem, Leaves, and Flowers Plants have four main parts: roots anchor them in soil, stems support the plant and transport water and nutrients, leaves produce food through photosynthesis, and flowers help with reproduction. Comparing Types of Flowers Different flower shapes Color variations in flowers Types of flower arrangements Comparing Types of Roots Taproots are thick and deep. Fibrous roots spread out widely. Different functions in plants. Functions of the Roots Key roles of plant roots Roots anchor plants in the soil, absorb water and nutrients, and store food for growth. Basic Structure of Animals Understanding Animal Body Parts Head contains sensory organs Torso houses vital organs Limbs for movement and support Functions of External Features of Animals Understanding Skin, Fur, and Feathers Animals have special features like skin, fur, and feathers. These help with protection, temperature control, and camouflage. Vertebrates and Invertebrates Understanding the Two Groups Vertebrates have backbones Invertebrates lack backbones Examples include fish and insects Characteristics of Vertebrates Key Features of Vertebrates Have a backbone Bilateral symmetry Complex nervous system
