P3 Fungi and Bacteria

TOPICFungi 🍄

Fungi come in different shapes and sizes. Examples include mushrooms, moulds, and yeasts.

📋Fungi — Key Characteristics

Feature	Detail
Food	Obtain food from other dead or living things (cannot make their own)
Reproduction	By spores 🍂
Growth needs	Warmth, air, moisture — prefer dark places
Movement	Cannot move by themselves (like plants)

🍄Mushroom Structure

In mushrooms, the spores are found under the cap in the gills.
In moulds, spores are contained in a spore bag found at the end of the stalk.

⚖️Fungi — Useful or Harmful?

	✅ Useful	❌ Harmful
Food	Eaten as food (mushrooms, truffles)	Cause decay and food spoilage
Baking	Yeast used to make bread	Cause decay and food spoilage
Nature	Break down dead plants and animals into simpler substances, returned to soil	Can be poisonous (fly agaric, death cap mushroom)
Medicine	Used to make medicine	Can be poisonous (fly agaric, death cap mushroom)

⭐Types of Fungi

Fungi can be grouped into three main types:

🍄 Mushrooms

Spores found under the cap in the gills
Examples: button mushroom, truffle

🟢 Moulds

Spores in a spore bag at the end of the stalk
Grow in warmth, moisture, and air
Prefer dark places

🍞 Yeasts

Used to make food such as bread
Single-celled fungi

💡 DID YOU KNOW? The largest living thing on Earth is a fungus! A honey fungus in Oregon covers over 2,384 acres — that's like 1,500 football fields! 🍄🌍

💡 DID YOU KNOW? Penicillin, one of the world's most important medicines, comes from a type of mould. It was discovered by accident in 1928! 💊🔬

TOPICBacteria 🦠

Bacteria can be found everywhere. They have different shapes and sizes, but they are so small that they can only be seen using a microscope — making them micro-organisms.

📋Bacteria — Key Characteristics

Feature	Detail
Size	Can only be seen with a microscope (micro-organisms)
Food	Obtain food from other dead or living things (cannot make their own)
Survival needs	Air, food, and water — like all living things
Growth	Warm conditions increase bacteria growth

⚖️Bacteria — Useful or Harmful?

	✅ Useful	❌ Harmful
Digestion	Help us digest food	Cause us to fall sick (e.g., from unwashed hands)
Food production	Making cheese and yoghurt	Cause us to fall sick (e.g., from unwashed hands)
Medicine	Making medicine such as insulin	Cause decay and food spoilage
Nature	Break down dead plants and animals into simpler substances (like fungi)	Cause decay and food spoilage

⭐Bacteria Shapes

Bacteria come in different shapes and sizes. Here are the main types:

📏 Rod-shaped

Look like tiny rods or capsules

⚽ Sphere-shaped

Round like tiny balls

🌀 Spiral-shaped

Twisted like corkscrews

💡 DID YOU KNOW? Your body has more bacteria cells than human cells! Most of them live in your gut and help you digest food. You couldn't survive without them. 🦠❤️

💡 DID YOU KNOW? Some bacteria can survive in boiling water, freezing ice, and even deep underwater near volcanoes! They are the toughest survivors on Earth. 🔥❄️

TOPICFungi vs Bacteria — Side by Side 🔄

Fungi and bacteria share some similarities but also have important differences:

	🍄 Fungi	🦠 Bacteria
Food	Both obtain food from other dead or living things (cannot make their own)
Reproduction	By spores	By splitting into two
Size	Some visible to naked eye (mushrooms)	Only visible with a microscope
Growth needs	Both need warmth, air, and moisture
Movement	Neither can move by themselves from place to place
Nature role	Both break down dead plants and animals into simpler substances

💡 DID YOU KNOW? Both fungi and bacteria are nature's recyclers! Without them, dead plants and animals would pile up forever. They turn waste into nutrients that new plants can use. ♻️🌱

TOPICCommon Questions ❓

🌿Comparing Ferns and Fungi

The bird's nest fern and mushroom are similar in how they reproduce. Both reproduce by spores.
The bird's nest fern and mushroom are different in how they obtain food. The bird's nest fern makes its own food, while the mushroom obtains food from other dead or living things.

🍞Conditions Necessary for the Growth of Mould

A slice of bread left on the kitchen table develops black patches after a few days.
The black patches are mould.
Mould grows in the presence of warmth, moisture and air.

🌑Mould Prefers to Grow in Dark Places

Bread A was left on the kitchen table and Bread B was left in the cupboard.
After a few days, Bread B had more black patches than Bread A.
This shows that mould prefers to grow in dark places.

💡 DID YOU KNOW? The green fuzz you see on old bread is actually millions of tiny mould organisms working together! Each one is a spore that grew into a new mould colony. 🍞🔬
