What does indeterminate growth mean in a plant quizlet?

Indeterminate growth: a type of growth characteristic of most plant organs, in which growth continues as long as the plant lives. Plants are capable of indeterminate growth because they have perpetually embryonic tissues called meristems. … Secondary growth allows for the plant to grow into thickness. Why is plant growth indeterminate?
Plant growth is unique because plants retain the capacity for unlimited growth throughout their life due to the presence of meristems at certain locations in their body. The cells of meristems have the capacity to divide and self-perpetuate.

Is plant growth determinate or indeterminate?

plant growth is generally indeterminate, i.e., plants retain the capacity for unlimited growth throughout their life, whereas it is determinate in the meristem which is consumed in the formation of an organ. What is a indeterminate plant?
Indeterminate varieties develop into vines that never top off and continue producing until killed by frost. They are preferred by home growers and local-market farmers who want ripe fruit throughout the season. Many, if not all, heirloom tomatoes are indeterminate.

How does secondary growth differ from primary growth in plants?

In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue. Are plants indeterminate?

Indeterminate varieties continue to grow and produce tomatoes all along the stems throughout the growing season. Indeterminate plants need extra-tall supports of at least 5 feet. … A few varieties are called semi-determinate or compact indeterminate because they are somewhere in between.

Frequently Asked Questions(FAQ)

Where does indeterminate growth occur?

Indeterminate Meristems In lower vascular plants, whose apical meristems have a single apical initial cell, division of the initial cell produces two very different daughter cells. One is large and retains the function of an initial; the other daughter is much smaller and lacks the capacity to divide indefinitely.

What is intermittent growth?

Intermittent growth is a common feature of growth cone motility, in both the optic chiasm ( A ), a decision region, and the optic tract ( B ), a straight path. … Frames were taken in the chiasm every 15 min, and in the tract, every 20 min. Asterisk indicates a break in the sequence of the frames displayed.

What does determinate mean for tomatoes?

Determinate (bush) tomato plants are bred to stop growing usually somewhere around 3′-4′ feet tall. When flowers blossom at the tips of the branches, the plant has reached its full height. The fruit of a determinate tomato plant ripens all at once.

Do trees have indeterminate growth?

Continuous growth, normally called sustained or indeterminate growth, ceases only when weather conditions are unfavorable. Trees with sustained growth are able to take advantage of favorable conditions by growing rapidly.

Are flowers determinate?

Which organism has the potential for indeterminate growth?

There are many other kinds of animals with the capacity for unlimited growth. For example, invertebrates, such as corals, never stop growing. This pattern is called “indeterminate” growth – adult size depends largely on environmental conditions. Most fish, amphibians, lizards, and snakes are indeterminate growers.

Where does secondary growth occur in plants?

The process of secondary growth is controlled by the lateral meristems, and is similar in both stems and roots. Lateral meristems include the vascular cambium and, in woody plants, the cork cambium (cambium is another term for meristem).

What is determinate meristem?

A determinate meristem usually produces a part of the plant that has a predictable size and form, such as the flower, whereas an indeterminate meristem produces parts of the plant that can grow for variable periods of time, and vary in size and shape dependent on the local environment (Sablowski et al., 2007).

What is the difference between indeterminate?

What’s the difference between determinate and indeterminate plants?

The determinate forms stop their shoot production once flowers form on the ends. Indeterminate tomato varieties will form flowers along the sides of the shoots but they continue to grow until weather conditions are no longer favorable.

How are determinate and determinate growth Different?

Think giant sequoias and other redwood trees. Indeterminate growth can also refer to sequential flowering that starts at the bottom and on the sides of a plant, and then moves in and up. Determinate growth is finite. It usually means the main stem ends with a flower or other reproductive structure.

Do all plants have indeterminate growth?

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.

Why do plants need secondary growth?

Secondary growth is the outward growth of the plant, making it thicker and wider. Secondary growth is important to woody plants because they grow much taller than other plants and need more support in their stems and roots. Lateral meristems are the dividing cells in secondary growth, and produce secondary tissues.

What is the difference between primary and secondary roots?

Answer: The primary root grows vertically downwards into the soil. Smaller lateral roots known as the secondary roots are produced on the primary root. … These roots grow in various directions and help in fixing the plant firmly into the soil.

What is a determinate?

1 : having defined limits a determinate period of time. 2 : definitely settled a determinate order of precedence. 3 : conclusively determined : definitive a determinate answer.

What are determinate and indeterminate structures?

1. When all forces in a structure is determined from equilibrium equations, the structure is known as statically determinate. When the unknown forces in a structure are more than the available equilibrium equations, that structure is known as statically indeterminate structure.

Is Early Girl determinate or indeterminate?

Early Girl bears lots of fruit for early harvest, but because the vines are indeterminate, they continue producing through summer. In our Alabama test garden, where conditions are ideal and the growing season is long, we harvest an average of 300 tomatoes from each Early Girl plant!

What is example of indeterminate growth?

Indeterminate growth is common among cold-blooded species, from tiny insects to large lobsters. One of the most common, and most unwelcome, indeterminate growers is the silverfish, a small wingless insect with a fishlike body and two long antennae, which lurks in many basements and in some kitchens and showers.

What is intermediate plant growth?

Intermediate-life plants are plants that have a growth and production cycle exceeding one year, but less than those of trees and vines.

Are snakes indeterminate growers?

snakes. Snakes have indeterminate growth, which means there is no terminal point in time or size for growth in their lifetime, but they can continue to increase in length until they die. Sexual maturity is reached in about two years by many snakes.

What is meant by Allometric growth?

allometric growth The regular and systematic pattern of growth such that the mass or size of any organ or part of a body can be expressed in relation to the total mass or size of the entire organism according to the allometric equation: Y = bx α, where Y = mass of the organ, x = mass of the organism, α = growth …

Is Cotton determinate or indeterminate?

Cotton is a perennial plant with an indeterminate growth habit and has a very dynamic growth response to environment and management.

Which inflorescence shows determinate growth?

Determinate inflorescence: Sympodial (cymose) growth. The terminal bud forms a terminal flower and then dies out. Other flowers then grow from lateral buds.
