Mulberries are a small deciduous tree that likes temperate to tropical climates. Most varieties have black fruit that is red when it is underripe, but some have white fruit that is green when it isn't ripe yet.
Mulberries can be eaten fresh or used to make jam or pies. Black mulberries are the only plant that the silkworm eats.
Mulch is a layer of material that you put on the ground around plants. Mulch keeps the soil from drying out, and can help keep it from getting too hot or cold.
Mulches can be made from many things, but the most common kinds of mulch are decorative gravels, pebbles, bark, wood chips and leaves. Mulches made from bark or leaves will slowly break down and make the soil better.
A mummy is a preserved dead body, animal or human. Mummies can be made by deliberately preserving them, or accidentally by extreme environmental conditions. The process of preserving a body is called mummification.
In ancient Egypt, it was common for dead bodies to be ritually preserved for burial. Mummified bodies typically had the internal organs removed and were then dried, by desert sand or salt, and anointed with oils and perfumes and wrapped.
A museum is a place where old and interesting things from all over the world are kept for people to come and look at. Museums are a great source of information.
Mushrooms are a type of fungus, and are not a plant. They come in a variety of sizes and colours. Some mushrooms are edible, but others are poisonous - poisonous mushrooms are often called toadstools. The top part of a mushroom is called the cap and the stem at the bottom is called the stalk.
Mushrooms reproduce in a similar way to ferns. They grow spores in gills under the cap, which gradually opens from a ball to a disc as the mushroom matures. Some mushrooms release their spores in an explosive puff. Spores look like fine black dust.
