    Plants can move and grow in a given direction, depending on different stimuli.    Moving/ growing away from a stimulus is called negative tropism. For example, roots have negative thigmotropism, so if they meet a rock in the soil, they grow away from it.    Positive tropism is growing/ moving towards the stimulus, for example, plant shoots growing towards the light.  You may download a short PowerPoint lesson about tropism in plants from this link https://drive.google.com/file/d/1HMf3NoGFmX0XeE4BUf9qZ5t70Yjn_MGS/view?usp=sharing Thigmotropism Gravitropism Phototropism Positive and negative tropisms Photoperiodism Long-day, short-day, and day-neutral flowers

Radishes are easy to grow – they do need special care and are no susceptible to many diseases. Radishes are ready to harvest after 1-2 months since planting the seeds.
