Does growth occurs uniformly throughout the plants?

Does growth occurs uniformly throughout the plants?

Growth at the tips leads to elongation of body parts and lateral (side ways) growth leads to increase in the thickness of stem and root. The rate of growth of a plant or plant part is not always the same during its life span. Sometimes it is slow and at other times rapid.

How does growth occur in plants?

Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to as primary growth, and is the result of cell division in the shoot apical meristem.

Is leaf growth indeterminate?

Most plants demonstrate indeterminate growth, growing as long as the plant lives. In contrast, most animals and certain plant organs, such as flowers and leaves, undergo determinate growth, ceasing to grow after they reach a certain size. Indeterminate growth does not mean immortality.

Why does growth in plants occur at specific areas?

The growth of plants occurs only in certain specific regions. This is because the dividing tissue, also known as meristematic tissue, is located only at these points. Depending on the region where they are present, meristematic tissues are classified as apical, lateral and intercalary (Fig.

Do leaves have secondary growth?

Secondary growth, or “wood”, is noticeable in woody plants; it occurs in some dicots, but occurs very rarely in monocots. Other plant parts, such as leaves and flowers, exhibit determinate growth, which ceases when a plant part reaches a particular size.

How secondary growth occur in plants?

In many vascular plants, secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium. Arising from lateral meristems, secondary growth increases the width of the plant root or stem, rather than its length.

How does leaves affect plant growth?

Mailny the chloroplasts are found mailny in the green leaves and other body parts of the plants. In the cells of green leaves abundant numbers of chloroplasts are found. These chloroplasts are the sites of the photosynthese. The stored food materials are utilised for future growth and development of plants.

Why does the growth of a plant occur in a specific regions where are the following are found 3 a intercalary meristem B lateral meristem?

The growth of plants occurs in specific regions, each growth point has a a reason. For example lateral meristem increase the girth of the plant, and intercalary help in growth of plants at the nodes. Lateral meristems are found on the lateral sides in the stem.

Where does growth in plants take place short answer?

In plants, the primary growth occurs in the roots and stems, the areas of apical meristems. All plants feature this type of growth.

Is secondary growth absent in leaves?

Roots and stems of monocot plants do not show secondary growth (due to absence of vascular cambium), with few exceptions e.g., Dracaena, Yucca, etc., which exhibit anomalous secondary growth.

Does leaf undergo secondary growth?

Do all plants undergo secondary growth?

Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium. Not all plants exhibit secondary growth.

How does the structure of a leaf affect its strength?

Many leaves rely on hydrostatic support arranged around a skeleton of vascular tissue for their strength, which depends on maintaining leaf water status. Both the mechanics and architecture of the leaf reflect the need for transportation and support.

Why do some leaves have white patches on the edges?

Leaves are mostly green in color. This is due to the presence of a compound called chlorophyll. This compound is essential for photosynthesis as it absorbs light energy from the sun. A leaf with white patches or edges is called a variegated leaf .

How are the two basic forms of leaves described?

Two basic forms of leaves can be described considering the way the blade (lamina) is divided. A simple leaf has an undivided blade. However, the leaf may be dissected to form lobes, but the gaps between lobes do not reach to the main vein.

Why is the shape of a leaf important for photosynthesis?

The flat, or laminar, shape also maximizes thermal contact with the surrounding air, promoting cooling. Functionally, in addition to carrying out photosynthesis, the leaf is the principal site of transpiration, providing the energy required to draw the transpiration stream up from the roots, and guttation.
