2.Carnivorous : Animals that eat other animals, lion, alligators.
3.Omnivorous : Animals that eat both of them, bear, cat and mouse.
>Humans are also carnivorous.

,Breathing of living things.
>Caterpillars take air through small holes on the side of their bodies.
>Fish takes air through gills, it breathes oxygen in water that is dissolved in water.
>Plants take air through small holes in its leaves called stomata (pores),these stomata are underside of a
leaf.
>Stomata inhale carbon dioxide and exhale oxygen.
>Humans breathe through their nose and mouth.

>A plant has a flower which makes seed, seeds grow to make a plant.
1.Seed, 2.Seedling, 3.Plant.

>Ostrich is the largest bird in the world, it can't fly.
>Hummingbird is the smallest bird in the world.

Parts of a plant.
1.Root : It grows in soil, it sucks water and minerals from soil.
2.Stem : It grows above the soil, it takes water and minerals from root to leaves.
3.Leaf : Leaves make food for plants, leaves are also called (kitchen, food industry).
4.Flower : It makes fruit which makes seeds.

>Rafflesia is the biggest flower in the world, it grows about 1m wide, it grows in the forest of Indonesia.

Kinds of root.
1.Tap-root : Some roots have one big part which is thick.
>This thick root is called tap-root.
>A tap-root has many small roots or root hairs that suck water and minerals from soil.
>The tip of the root has a root cap.
2.Fibrous root : Some roots have many small branches of the same size.
>These roots are called fibrous roots.
>They do not store much food.
>Plants living in salt water (marshes and swamps) have arched roots which hold them firmly in the mud.

Parts of a leaf.
1.Leaf stalk : The part in which leaf is joined, it jointed in the stem.
2.Midrib : It carries water and minerals(food).
3.Leaf veins : Veins also carry water and minerals, in some leaves veins make a network or web.
4.Leaf blade : It is the edge of a leaf,some plants have (lobbed edge, edge like-saw, simple edge).

Types of a leaf.
1.Simple leaf : One leaf growing on a leaf stalk is called a simple leaf.
2.Compound leaf : When two or more small leaves grow on a leaf stalk is called compound leaf.
>The small leaves of a compound leaf are called leaflets.
>The green color of a leaf is due to chlorophyll.
>Plants make chlorophyll with sunlight and warmth.

, >In hot summer plants produce chlorophyll.
>As days become shorter and cooler(winter) , the production of chlorophyll slows down because plants
don't get warmth.

Functions of a leaf.
>The food of a plant is glucose.
>It is sweet like sugar.
>A leaf makes glucose with the process called photosynthesis.

>Bryophyllum is a plant, the tiny Plants grow on the edge of its leaves.
>Some fruits have one and some fruits have many seeds.

Parts of a seed.
1.Hole : Air and water go into the seed through the hole, the hole is joined to the fruit.

leaves (peas).

Source of light.
1.Luminous object : Objects that give out light on its own called luminous i.e (sun, stars, torch, bulb,
candle).
2.Non-luminous object : Object that does not give out light called non-luminous i.e (book, table, pen,
moon).
>Moon is non-luminous because it does not give light, when the Sun shines on it we can see the Moon.

1.Transparent : Something through which light can pass clearly (water).
2.Translucent : Something through which light can pass but not clearly (Forest glass, butter paper).
3.Opaque object : Objects through which light can not pass (brick, table, book).
