What are the important characteristics of plant growth?

Characteristics Of Plant Growth

• Plant Growth Is Indeterminate. Plants have the unique ability to grow indefinitely throughout their life due to the presence of ‘meristems’ in their body.
• Plant Growth Is Measurable.
• Meristematic Phase.
• Elongation Phase.
• Maturation Phase.
• Arithmetic Growth.
• Geometric Growth.

What are the 5 main groups of plants?

Each of the more than 350,000 species of plants differs from every other species in one or more ways. However, plants also have many features in common. Based on these similarities, scientists are able to classify distinct plants into 5 groups known as seed plants, ferns, lycophytes, horsetails, and bryophytes.

How many Phylums are in the plant kingdom?

Depending on definitions, the animal kingdom Animalia contains approximately 31 phyla; the plant kingdom Plantae contains about 14, and the fungus kingdom Fungi contains about 8 phyla.

What is growth and development in plants?

Plant growth could be defined as the increasing of plant volume and/or mass with or without formation of new structures such as organs, tissues, cells or cell organelles. Growth is usually associated with development (cell and tissue specialization) and reproduction (production of new individuals).

What are plant growth regulators 11?

Plant growth regulators are the chemical substances that control the aspects of growth and development within the plants completely. They are also known as plant growth hormones or phytohormones.

What is plant growth and development?

Plant Growth and Development involves study of the control and coordination of processes in cells, organs, and/or whole plants, including, for example, changes in gene expression in response to environmental conditions such as climate change.

Why is growth and development important?

The assessment of growth and development is very helpful in finding out the state of health and nutrition of a child. Continuous normal growth and development indicate a good state of health and nutrition of a child. Abnormal growth or growth failure is a symptom of disease.

What are the developmental stages of a plant?

In higher plants, however, growth is indeterminate. There are three principal stages of growth – the log, the lag, and the senescent stage. Cells reach the stage of differentiation when they lose their capacity to divide. Learn in detail about the growth and hence developmental stages of a plant.

What are the important factors affecting the growth of plants?

The important factors affecting the growth of plants include: 1 Temperature. 2 Light. 3 Water. 4 Soil Nutrients. 5 Plant Growth Regulators. More

What are the characteristics of plants?

Plants are capable of growing throughout their life due to meristematic tissues present in certain parts. Growth can be measured by an increase in cell number, length, area, volume and dry or wet weight. Primary Growth: Apical meristems of roots and shoots is responsible for primary growth.

Why do meristems have the ability of Division and grow constantly?

These cells of the meristems have the ability of division and grow constantly. The plant body is made up by the cells which lose the capacity to divide. The growth form, where cells are constantly added to the body of the plant through the action of meristems is referred to as the open form of growth. Q.3.
