Summary!!!~

On thursday,Miss Lim taught us to:
Recognize that plants can reproduce from various plant parts.
Examples: -spores
-undergroung stem
-leaves
-suckers
AND......charateristics of plants reproduce from underground stems !

Summary
On thurday miss lim teach us, 1.The different ways where plants reproduce from plant part, 2.Recognize that plants can reproduce from various plants parts
-Spores
-Underground stem
-Leaves
-Suckers
Charcteristics of plants reproduce from undergrounf stems
1.It has buds and leaves
2.Leaves are not green
3.They can be scaly and fleshy
eg:
-A sealing wax palm
-A heliconia plant...
(Sucker grow beside of the old plant,it grows up right shoots.)
Reproduce from leaves
1.Some plant like byoplnyllum,reproduce from leaves.Such leaves are usually thick and fleshy.
Characteristics for plants which reproduce from leaves
-Leaves are usually thick and fleshy
-The bud will grow into new plant when mature leaves fall in the ground or the buds.
-Some buds may even start to grow roots while it is still on the leaves.
Advantages of reproduction from plant parts
-This process does not need wind or insects for pollination and dispersal
-No fertilisation is required.
-Desirable or beneficial qualities are passed in to young plants without any change.
Artificial methods of reproduction
-Stem cutting
-Leaves cutting
-Budding
Stem cutting
-Certain plant like the rose,hibiscus,bougainuillea,etc....do not produce seeds because of climatic condition (hight temperatures and heavy rainfall)
-They can be reproduce by aretificial methods like stem cutting
Leaf cutting
-Part leaf cutting
-Whole leaf cutting
Budding
-In budding,the bud from one plant is jioned to another plant called the stock.

Summary!!!

Seeds
-Flowering plants reproduce from seeds.

Spores
-Non-flowering plants such as Fern.
-Do not reproduce from spores unlike seeds.

*Some flowering plants can reproduce from plant parts such as stems,suckers and leaves.
*Under ground stems are usually swollen because they store food for the plant.

Suckers
-Plants like Banana and Pineapple reproduce by suckers.
-These shoots develop from a certain part of the stem.

Leaves
-Leaves plants like the Bryophyllum,Begonia and African violet can new plants.
-Such leaves are usually thick and fleshy.
On Thursday Miss Lim though us about plants that can reproduce from various plant parts such as:
-spores
-underground stems
-leaves
-suckers
First we learnt about spores.The spore bags will burst and the wind will carry the spores away.
Second we learnt about underground stems.Here are some examples of underground stems:
-ginger
-potato
-onion
Here are some characteristics of under ground stems:
-It has buds and leaves
-Leaves can be scaly and fleshy
Next we learnt about suckers.Examples of suckers are:
-wax plam
-Banana plant
-Pineapple plant
-Heliconia plant
Suckers are shoots that grows beside the parent plant.
Lastly,we learnt about plants that reproduce from leaves.Example of such plants are
-bryophyllum leaf
-african violet
-begonia plant
Characteristic of such leaves are:
-Leaves are thick and fleshy
-Buds will grow into new plant when mature leaves fall into the ground.
Faster method of reproduction are:
-stem cutting
-leaf cutting
-budding
Leave cutting:
-part leaf cutting
-whole leaf cutting
In budding the bud from one plant is joined to another plant called the stock
I also learnt that cetain plants like Rose,Hibiscus,bougainvillea do not reproduce seed because of climatic conditions.

Surmmary of Science unit 5

Today in school,we learn about Reproduction from plant parts.The are many kind of ways to reproduce from various plant parts.There are spores,underground stem,leaves and suckers.Non-flowering plants such as ferns reproduce from spores.Spores are kept in a bag called Spores bag and they are found on the underside of a fern leaf.Example of plants reproduce from spores:Bird nest ferns,Sword ferns and many more. Those plant reproduce by underground stem have buds and leaves,but leaves are not green and they can be scaly and flesly.Example of underground stem :potatoes,ginger ,onion and chestnut.Reproduce by leaves usually thick and flesly .Plants like banana and pineapples reproduce by producing upright shoot called suckers ,which develop from a certain part of a stem.Suckers grow into a new plant when the parent plant dies.Example of suckers:Sealing wax plam ,heliconia plant,banana tree and pineapple tree.There is a lot of ways to reproduce a plant:stem cutting,leaf cutting, budding and many more.Example of stem cutting:roses,hibiscus and bougainvillea.There are many ways for leaf cutting,you can cut the leaves into half or cut the stem of the plant which is called a full plant.In budding,the bud from one plant is joined to another plant called the stock.Plants have characteristics similar to the parent plants.

(heliconia)(african violet)

Today in Science lesson , Miss.Lim thought us about reproduction from plant parts thy are underground stem , sucker , leaf and flower.She also told us what fruit and vegetables are from these reproductions.The ubderground stem are potato,ginger,onion,tulip and yam.The suckers are banana plant,sealing wax palm,pineapple and heliconia.Next is the leaves they african violet and the begonia plant.Miss Lim also thought us about the stem cutting and budding.The stem cutting plants and the budding plants are.This is the stem cutting plants are rose,hibicus and the sugarcane the last are the budding plants they are the rubber tree and th apple tree.This are what Miss Lim thought during the Science lesson.
