Galls are abnormal growths that occur on plants in response to various stimuli, often from insects or pathogens. The cells within galls undergo hyperplasia and hypertrophy, leading to increased cell division and enlargement. This results in the formation of a mass of plant tissue that can serve as a habitat and food source for the inducing organism. Ultimately, the galls can affect the overall health and growth of the plant, depending on their size and location.
What else can I help you with?
Large numbers of bacterial cells are not found in crown galls because?
Large numbers of bacterial cells are not found in crown galls because the bacteria responsible for gall formation (Agrobacterium tumefaciens) transfer only a small portion of their genetic material to the plant cell, triggering the formation of the gall. The bacteria do not actively multiply within the gall itself.
What will happen if put plant cell in salty water?
Salt draws water from plant cells. This causes the cells to dehydrate and the plant to shrivel up and die.
Which organism naturally possesses the Ti plasmid?
The Ti plasmid is naturally found in the bacterium Agrobacterium tumefaciens. This bacterium is known for its ability to transfer genetic material into plant cells, causing the formation of galls or tumors.
What would happen if the chloroplast was not present in plant cells?
Plant cell would be dead. It is the process which give fuel for respiration
Why are galled roots when inoculating nematodes to the roots of test plants?
Galled roots occur when nematodes invade plant roots and trigger a response that leads to abnormal growths or galls. These galls form as a result of the plant's defense mechanisms reacting to the nematode's feeding, which disrupts normal root development and nutrient uptake. Galled roots are often used in studies to assess the impact of nematodes on plant health and to evaluate the effectiveness of control measures. Observing these galls helps researchers understand the interactions between nematodes and their host plants.
Does photosynthesis happen in all plant cells?
No, Photosynthesis happen only in those plant cells having chloroplasts.
What corn pests causes galls to develop on the plant?
The primary pest that causes galls to develop on corn plants is the corn leaf aphid (Rhopalosiphum maidis), which can induce galls through its feeding behavior. Additionally, the Hessian fly (Mayetiola destructor) can also lead to gall formation as it lays eggs in the plant tissues, causing abnormal growth. These galls can weaken the plant and reduce its overall yield.

What has the author Edward T Connold written?
Edward T. Connold has written: 'British oak galls' -- subject(s): Galls (Botany), Oak, Diseases and pests 'Plant galls of Great Britain'
What are plant tumors?
A localized proliferation of plant tissue forming a swelling or outgrowth, commonly with a characteristic shape and unlike any organ of the normal plant. Plant tumors or galls usually form in response to the action of a pathogen or a pest. These are also known as Galls...
Does photosynthesis happen in cells?
yes it is happening. It is happening in the plant cells.
How does osmosis happen in plant cells?
In a wilted plant- the wilted plant becomes firm again.
What will happen if a plant without functional phloem cells?
Hh
Where does a plants photosynthesis happen?
it happens in the chloroplasts of the plant cells
Does respiration happen in all cells including plant cells?
Only respiration happens in both.
What will happen if put plant cell in salty water?
Salt draws water from plant cells. This causes the cells to dehydrate and the plant to shrivel up and die.
Does chloroplast happen in plant cells animal cells or both?
Chloroplasts are in plants.They are never found in animals.
