6 Choose the most appropriate word from the boxes to fill in the blanks. Irritability Respiration Movement Reproduction Nutrients Growth Excretion There are seven characteristics of living organisms. Nutrition is the taking in of which are needed to build bodies and provide energy. The energy is released from the food in a chemical reaction called. Waste substances produced in the body cells are removed by. Living organisms get bigger. This is called. They can sense changes in their environment and respond to them, which is called. Sometimes, these responses involve, for example a plant closing its leaves at night or an animal running away from something. Living organisms can make more of themselves. This is called. Cytoplasm Chloroplast Cell membrane Ribosomes Cell wall Mitochondrion Nucleus Chlorophyll DNA Organelles All cells are surrounded by a which controls what goes in and out of the cell. Plant cells also have a which helps to hold the cell in shape. Cells contain a watery jelly called. There are also several different structures called. The of the cell contains chromosomes, made of. These control the activities of the cell. They provide instructions telling the cell what proteins to make. Proteins are made on the. Energy for the cell is provided by respiration, which happens inside the. Some plants cells have which contain a green substance called.

7 Sperm Tissue Food Muscle Differentiation Organ Trachea Nerve Epithelial In the human body, different cells become specialized to carry out different functions. This is called. Cells that cover a surface are called cells. The cells that cover the inside of the make mucus which traps dirt and bacteria. cells have a long tail that helps them to swim towards the egg. Egg cells contain for the new embryo. cells carry electrical impulses in the body. cells can contract, which means get shorter. A group of cells carrying out the same function is called a. An, such as the stomach, is made of many different tissues. Write the balanced equation for photosynthesis. Word equation: Chemical equation: Show how equation was balanced: Make a food chain using the following animals; shark, pond weed, small fish, tadpole. Show the direction of energy flow using an arrow and state the rank of each such as producer etc. Name the three pyramids related to the food chain 1. Pyramid of 2. Pyramid of 3. Pyramid of
