science

• Science must be accountable and responsible by considering a good scientific attitude, following the scientific process, and the products or outcomes of the process.
• The Scientific Process can take the form of Reports, Theories, Laws, Principles.
• This refers to the scientific knowledge that has been accumulated over the years.
• Attitude in science refers to the way in which the scientist approaches their work.
• Some attitudes of scientists include curiosity, logic, open-mindedness, productivity, and discipline.
• The Scientific process is the procedure undertaken by a scientist to answer scientific questions.
• The process refers to the steps we take to get to the results.
• Discussion is a crucial part of the Scientific process.
• There are many types of cells that vary in size, shape and the organelles present within them.
• Most cells contain many of the same structures.
• A cell that is not specialised for a specific job, or a cell drawn to represent the general features in a cell is called an Unspecialised cell.
• The main cell structure is composed of the cell membrane, the nucleus, the cytoplasm, and within the cytoplasm are tiny structures that help the cell function, these structures are called organelles.
• Different types of life, such as plants and animals, have distinct differences in their cells.
• The cell membrane surrounds the cell and controls what enters and leaves the cells.
• The nucleus is one of the biggest organelles, it contains the chromosomes (DNA) and controls the chemical reactions in the cell.
• The cytoplasm is a watery jelly held within the cell membrane, it contains the cell organelles and is the site of many metabolic reactions.
• Mitochondria are where respiration takes place, releasing energy from food.
• Vacuoles are a storage organelle that stores waste products in animals and food substances in plants.
• The cell wall is a tough layer that surrounds the cell made of cellulose, it helps keep the shape of the cell.
• Chloroplasts contain chlorophyll which is necessary for the photosynthesis process, photosynthesis is the process by which plants make food.
• Starch grains are where the plant stores the sugars that are made during photosynthesis.
• Plant cells have cell walls and animal cells do not.
• Plant cells have one large vacuole and animal cells have several small vacuoles.
• Only plant cells contain chloroplasts (which have the pigment chlorophyll).
• Plants have one large permanent vacuole and animal cells have many small temporary vacuoles.
• Plants have starch grains and animals do not.
• Animals do not have glycogen granules and plants do.
• Plants have glycogen granules and animals do not.
