Leaves and photosynthesis

Photosynthesis

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Plants need only light energy, CO₂, and H₂O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis.

Leaves and photosyntesis.

To mahe photosynthesis the plant need glucose, the glucose need water and sunlight (the leave receive the sunlight).During this process  ,the plant produce O_{2  or oxygen that is necessary for humans and animals}

What this module is about

In the study on the growth and development of plants, you need to be familiar with the parts of plants and their functions. There are three lessons prepared for you in this module:

�� Lesson 1 – The Vegetative Parts of Plants

�� Lesson 2 – The Reproductive Parts of Plants

�� Lesson 3 – Seed Germination

What you are expected to learn

After going through this module, you are expected to:

1. Differentiate between the vegetative and reproductive parts of a plant;

2. Identify the vegetative and reproductive parts of plants;

3. Describe how plants are structurally designed to perform the different life

processes; and,

4. Explain the requirement of plants for growth and development.

How to learn from this module

1. Read carefully the instructions given.

2. Answer the pre-test first.

3. If you are told to go out and visit a garden, do not hesitate to do so. You may be asked to go to a place nearby. It may be a backyard, school ground or any vacant lot where plants grow.

4. Fill up the designated boxes for any drawing/labels required.

5. Compare the drawings and diagrams in this module with actual specimens.

Monocotyledons and Dicotyledons 

Monocots and Dicots are two types of plants that develop from the Phylum Angiosperm (Plants with protected seed). They differ in…

MONOCOTS	DICOTS
Their leaves are sessile.	Their leaves have a petiole.
The blade is large and narrow.	The blade oval-like form and broad.
Their leaves have a parallel venation.	Their leaves have netted venation.
Their flower has a number of petals of multiples of 3 (3,6,9,…)	Their flower has a number of petals of multiples of 4 of 5 (4,5,8,10,…)
They have fibrous root.	They have taproot or adventitious root.

The Vegetative Parts of the Plant

Plants have organs, and they have different functions. Vegetative organs of a plant are: Roots, stem, and leaves, and could be used for asexual reproduction, that is why they are not responsible for the reproduction, but yes for the life cycle, growing process, and maintenance of the plant.

Roots

Roots are necessary for the plant, because they hold the plant underground and absorb water and nutrients from the soil for the plant.

 The root tip, or primary root, is the first one that develops from the plant. 

 

Compare seedlings or young plants with the diagrams upwards and see if they are monocots or dicots…

Common name	Taproot	Fibrous	Adventitious
Lirio		X
Trebol	X
Paragüita			X

Answer the following questions:

1. Differentiate the three types of root systems.

Taproot: 1main root, many thick lateral roots.

Fibrous: Many long and thin lateral roots.

Adventitious: Roots that grow from the stem or leaves.

2. What is the advantage of a taproot over the other types of root systems?

Taproots are thicker and can get deeper in the soil, and also it is more organized.

3. Is a carrot a vegetable or a root? Why do you say so? What about the radish? Sweet potato?

Carrots, radishes and camotes have characteristics of both: roots and vegetables, because they grow underground, even though they don´t have lateral roots; but the plant upwards doesn´t have a stem; so, in my opinion is a combination of both.

Activity 1.3

LEAF VENATION

1.    How many plants in your garden have netted venation?

2.    Parallel venation?

3.    What group of plants there are in your school? Monocots, dicots, both?

There were 18 with netted venation, 12 with parallel and 1 fern.

So there are more Dicots than Monocots:

Types of roots.

Types of roots

There are therre roots system:

Their names are: 

Tap root: Taproot is one in which the primary root becomes the main root of the plant.It have small lateral roots.It also occur in dicot plants.

Adventitious root: They are the roots that are in different parts of the plant. It occurs  in dicot plants.

Fibrous root: In monocotyledonous plants, the radicle is short lived and is replaced by numerous roots of more or less equal size.They are in monocot plants.

Does magnetism affect the growth of plants?

Hypothesis:

Our hypothesis is that the plants incline to the magnets and it can affect the growth of the plant

Theorical background

Magnetisnm:

Magnetism is part of electromagnetism, which is one of the forces of nature.  The motion of charge particles called electrons produce magnetic forces.  This shows the relationship between magnetism and electricity. Magnetism was known in ancient times by the Greeks, Romans, and Chinese.

Tropism: A tropism is a fixed, automatic, or inherited plant movement in response to a simuli.  A positive tropism is when there is movement toward the source of stimulation

Plant trospism : The type of tropism used in this experiment is called a geotropism.  Geotropism happens when the plant germinates and the young root turns downward

Radishes : The type of radish used in this experiment is called a spring radish.  Radish is a common name for a member of the biennial herbs of the mustard family.  Radishes originated in China.

Magnetism is the force generated by any moving charged particle or charged particles. A magnetic field is the result of the motion of a charged particle or charged particles, and this field is generated in no other way. Any time a charged particle moves, it creates a magnetic field around its path of travel. There are no exceptions that we know of. Magnetism is a term that speaks to the phenomenon associated with a magnetic field and with its action on other things.

The creation of a magnetic field by a moving charge or moving charges is this fundamental concept that is behind the term electromagnetic force, which is one of the four fundamental forces in the universe. Electricity and magnetism are tied together inextricably because of this

Does magnetism affect plants growth?

The effect of the electric field intensity on the growth of the bean

sprouts are presented. The study is focused on the growing rate of the

height of the stems and the length of the roots. The bean sprouts are

experimented under the condition among without electric field, with

electric field at 10 kV/m and 25 kV/m, respectively. The growing rate

of bean sprouts have been observed every day for 5 days. The

experimental results indicate that the bean sprouts under high

electric field intensity have a better growth comparison to the low

electric field intensity based on statistical analysis.

How do plants grow and change?

Plants need some primary needs to grow and change: They are water and sunlight.

The plants start off as a seed and then slowly  develops into a seedling.During this moment the embryo help the seed to supply food.

Later the seed make the root grow. They need also carbon dioxide and oxygen to grow. After a long time,with good conditions for the plant,the stem and the leaves will appear.

Objectives :

The objective of this experiment is to determine if magnets affect the growth of radish plants.

This experiment is to improve that the growth of the plant can be modifying by magnetism.

The information gained from this experiment might help farmers and gardeners by showing them if it is better for radish plants to be near magnets so that they might grow

5. Do this with all of the pots except for 3 of them. 

6. Place the pots on the trays. 

7. Put the shop light and the grow lux bulbs together. 

8. Hang the shop light from the ceiling or from two chairs.

 
9. Place the trays with the pots on them under the shop light.

 
10. Turn on the light.

 
11. Give each pot 1/2 a cup of water to get the soil moist. 

12. Give each plant fifty drops of water each day for four weeks. 

13. Set the timer to turn the light off at 7:30 P.M and turn the light on at 7:30 A.M. 

14. Examine the plants at least once every other day after the first week. 

15. Then collect the data that you need.
