Plant growth

Plants differ in the way they grow and reproduce from animals. The animal passes during its growth stage at a specific stage called maturity. Adult plants continue to grow and do not stop, but they do not reach the so-called maturity phase, due to differences in their composition. , And in this article we will talk about the conditions, manifestations, and stages of growth of girls.

Plant growth

Divided into external and internal manifestations, as follows:

External appearances

Size: The fruit reaches the same size as its class.
Shape: The fruit becomes round without a corner, and also similar to its class, in addition to a shiny wax layer on the surface of the fruit can not be removed with nails.
Color: Some fruits change color from dark green to ovarian green, while others show creamy lines on top (floral tip), and if the proportion of colored fruits to 20%, this indicates the complete growth.
Separation: The fruit is easily separated from the stem.

Internal features

It is a semi-gelatinous substance within the seed holes, which may be two or more glands.
Slip fruit and uninterrupted when trying to cut it knife.
The seed inside the fruit is solid and surrounded by semi-gelatinous material, and there is a pink color inside the fruit.

Phases of plant growth

The majority of green plants pass through four stages during their growth:

Germination

At this stage the seed begins to grow, but there must be some conditions, in order to grow properly, namely:
- temperature: Some plants live in warm areas, but die or delay in growth if placed in cold areas, and vice versa.
- Humidity: Where it works to increase the softness of the shortness, which you get from the soil.
- Good ventilation: So as to facilitate access to oxygen, which is necessary during the germination process.
After these conditions are available, and the seed is placed in the soil, they undergo the following stages:
- Soak the seed into water, then swell it until its size doubles.
- The appearance of the root and leg, the part of the root is called a lower embryonic pedal, and the part of the leg is called the upper embryonic pedal.
- Root survival in the soil, so as to help the plant absorb mineral salts and water from the soil, to get its food.
- The leg is released from the soil, the appearance of the seed, and then the leaves form. Here the plant is completed and able to carry out the process of photosynthesis, and make its own food.

Water movement

The movement of water within plants occurs in the following steps:

The absorption of water and mineral salts by the roots from the soil, through the so-called characteristic of the caraway.
On arrival leaves, where it is used with salts to produce food.
Go to the rest of the plant through the bark.

Plants lose excess water through the holes in their leaves, a process called the process of transpiration, where plants protect from the high temperatures resulting from sunlight.

Photosynthesis

This process occurs within small bodies in green plants, called green plastids, by the following steps:

Absorption of sunlight by chlorophyll.
Carbon dioxide with water and mineral salts, to produce food.
Exits oxygen, which is necessary for the breathing process in humans and animals.

Breathing

This process occurs during the night and day, which results in:

Energy production, carbon dioxide, water.
Use the resulting energy for growth, reproduction, and compensation.

Feeding plants

Also called parasitic; are dependent on external sources to get their food, so as to grow and multiply, for example:

Glutinous: It grows on tree roots.
Indian pipe: which depends on the food on organic matter produced by fungi.
