PLANTS REPRODUCTION

PLANTS REPRODUCTION:

1.   Plants can reproduce. They produce young plants.
2.   If a plant does not reproduce it will become extinct.
3.   Plants are food for many animals as well as for humans.
4.   Animals that eat other animals also depend indirectly on plants for their survival.
5.   We as well as these animals will not survive without plants.
6.   Plants reproduce in many ways.
7.   Different types of plants reproduce in different ways.
8.   Plants can reproduce by :
     (a)   seeds
     (b)   spores
     (c)   suckers
     (d)   stem cuttings
     (e)   leaves
     (f)   underground stems
     (g)   runners
9.   Plants need to reproduce in order to continue to exist.   

SEEDS:

1.   Most flowering plants reproduce from seeds.
2.   Examples of plants that reproduce from seeds are :

• balsam
• corn
• durian
• tomato
• papaya

3.   The seeds of most plants are dispersed by animals.

4.   The animals eat the fruits and the seeds are thrown away. Small seeds are passed out in the faeces of animals.

5.  The seeds germinate and produce new plants.

SPORES:

1.  Non-flowering plants reproduce from spores.
2.  Examples of plants that reproduce from spores are :

• ferns
• mushrooms
• mosses

3.   Spores are very tiny and light. They are easily carried away by wind.

4.   Spores germinate and produce new plants.

SUCKERS :

1.   Examples of plants that reproduce from suckers are :

• bananas
• pineapples
• cannas
• some palms
• bamboos

2.   Suckers grow around the parent plant.

STEM CUTTINGS :

1.   Examples of plants that reproduce from stem cuttings are :

• hibiscus
• rose
• tapioca

2.   This type of reproduction does not occur naturally.

3.   Humans use this method to reproduce more plants.

LEAVES :

1.   Examples of plants that reproduce from leaves are :

• bryophyllum
• begonia

UNDERGROUND STEMS :

1.   Examples of plants that reproduce from underground stems are:

• potato
• onion
• ginger
• water lily

2.   The underground stems store food for the new plants.

RUNNERS :

1.   Examples of plants that reproduce from runners are :

• strawberry
• grass

2.   A runner is a horizontal stem that grows roots.

3.   New plants that grow from runners grow in a row.
