Biology

• If a person takes in more energy than they use, their body mass will increase
• The total energy you need from your diet depends on your size, lifestyle, age and gender
• Metabolic rate is a measure of the rate at which chemical reactions take place in our body's cells.
• Seeds can be dispersed by animals or by wind
• When pollen grains are transferred from an anther to a stigma, this is called pollination.
• Pollen grains are produced by the anthers
• The carpel is made up of the stigma, the style and the ovary which enables fertilisation
• Cross-pollination increases variation within a plant species
• A plant's embryo grows by mitosis.
