| What is Photosynthesis? | When green plants convert light energy into chemical energy. The light energy is used to convery carbon dioxide and water into oxygen and glucose. |
| Stages of Fertilization - Part 2 | Inside the ovule the pollen fuses with the ovum After fertilization seeds are formed which will be dispersed in many different ways. |
| Equation of Photosynthesis | Carbon dioxide + water -^- oxygen + glucose |
| Stages of Fertilization - Part 2 | Inside the ovule the pollen fuses with the ovum After fertilization seeds are formed which will be dispersed in many different ways. |
| Pholem | Speciliased cells that transports glucose from the leaves to the rest of the plant, including the stems and roots |
| Stages of Fertilization - Part 2 | Inside the ovule the pollen fuses with the ovum After fertilization seeds are formed which will be dispersed in many different ways. |
| Xylem | Specialised tissue that transports water from the roots to the rest of the plant. |
| Guard cells | These cells control the size of the opening called the stomata |
| Stomata | Gases such as Oxygen, Hydrogen and Cabron Dioxide diffuse through these openings. They are used for gas exchange, thoe Carbon dioxide comes in and the oxygen comes out. |
| Pollination | The transfer of pollen from the anther of one plant to the stigma of another using a pollinator |
| Fertilization | The fusion of a male and female gamete (sex cells) |
| How petals attract pollinators | Petals are usually colourful to attract pollinators such as insects or birds. Insects are more attracted to the perfume let out by the plant |
| Stages of Pollination - Part 1 | Pollinators are attracted to flower by either colour or scent |
| Stages of Pollination - Part 2 | Pollinators reach deep into the flower to get the nectar for themselves, which is food for them. As the enter the flower, pollen from the anther gets rubbed onto them. |
| Stages of Pollination - Part 3 | Pollinators move to different flower to get more nectar. As they enter next flower, the pollen from the flower before get rubbed onto the stigma of the new flower. |
| Stages of Fertilization - Part 1 | Pollen grains get stuck on stigma after pollination A pollen tube starts to grow donw towards the ovary. |
| Stages of Fertilization - Part 2 | Inside the ovule the pollen fuses with the ovum After fertilization seeds are formed which will be dispersed in many different ways. |
