Junior Science – Living things Living things – Learning objectives 1. Understand how to use a simple key to identify plants and animals, including vertebrates and invertebrates. 2. Investigate the variety of living things by direct observation of animals and plants in their environment; classify living organisms as plants or animals, and animals as vertebrates or invertebrates. 3. Identify the basic life processes and characteristics common to all living organisms: nutrition, respiration, excretion, growth, reproduction, movement and response. Living things – Notes • Biology is the study of living things (organisms). • Living things have the following seven characteristics: – nutrition – movement – respiration – response. – excretion - growth – reproduction • The main differences between animals and plants are: – Animals move from place to place but plants do not. – Animals take in food but plants make their own food. – Animal cells do not have a cell wall but plant cells do have a cell wall. 1 Junior Science – Living things • Invertebrates are animals that do not have backbones. • Vertebrates are animals that have a backbone. • Living things can be identified and named using keys. 2 Junior Science – Living things Use the plant key below to identify these trees 1 = ____________ 2 = ___________ 3 = _________ 1.
