Which of the following describes the properties of ferns Brainly?
Answer: C. They have vascular tissue such as xylem and phloem and reproduce with spores. Explanation: This is the correct answer for Pennfoster.
What is ferns plant?
fern, (class Polypodiopsida), class of nonflowering vascular plants that possess true roots, stems, and complex leaves and that reproduce by spores. The ferns constitute an ancient division of vascular plants, some of them as old as the Carboniferous Period (beginning about 358.9 million years ago) and perhaps older.
Which statement best describes Hydrotropism in plants?
Answer: The roots of a plant grow toward moist soil. correct tysm!
What is Hydrotropism give example?
Hydrotropism is a form of tropism characterized by the growth or movement response of a cell or an organism to moisture or water. An example of positive hydrotropism is the growth of plant roots towards higher relative humidity level.
What is the example of Hydrotropism?
Hydrotropism means the tendency to grow or tend to reach the area with moisture content like the movement of roots towards high humidity level. Examples of hydrotropism plants are tomato roots, radish roots or even carrots.
What is Chemotropism give an example?
The growth of a plant part due to chemical stimulus is known as chemotropism or Chemotropism is the movement of a part of the plant in response to a chemical stimulus. The growth of pollen tube towards the ovule induced by a sugary substance as stimulus. This is an example of positive chemotropism.
What are the 4 types of tropism?
Forms of tropism include phototropism (response to light), geotropism (response to gravity), chemotropism (response to particular substances), hydrotropism (response to water), thigmotropism (response to mechanical stimulation), traumatotropism (response to wound lesion), and galvanotropism, or electrotropism (response …
What is positive Thigmotropism?
A positive thigmotropism is a response towards the touch stimulus whereas a negative thigmotropism is a response away from the touch stimulus. Examples of positive thigmotropism are the growth of ivy on walls upon contact to walls and the coiling of tendrils or twiners upon contact to objects for support.
What is an example of negative tropism?
Negative tropism is the growth of an organism away from a particular stimulus. Gravitropism is a common example which can be used to describe negative tropism. Generally, the shoot of the plant grows against gravity, which is a form of negative gravitropism.
Is Gravitropism positive or negative?
Gravitropism ensures that roots grow into the soil and that shoots grow toward sunlight. Growth of the shoot apical tip upward is called negative gravitropism, whereas growth of the roots downward is called positive gravitropism.
What are examples of Gravitropism?
For instance, the roots of the plants grow towards the gravitational field whereas the stem grows away from the gravitational field. The downward growth of roots is an example of a positive gravitropism whereas the upward growth of roots is an example of negative gravitropism.
What is a plants response to gravity called?
Gravitropism is the ability of plants to perceive and respond to the gravity vector and orient themselves accordingly.
What is the process of Gravitropism?
Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards).
Why do plants grow up against gravity?
The phenomenon of plants growing upwards against gravity is known as Negative Geotropism. The plant shoots grow towards sunlight as they require the sun’s energy to perform photosynthesis. while the plant roots grow away from the sunlight which is known as Positive Geotropism. Hope this helps!
What are the advantages of Gravitropism to plants?
Plants sense and respond to gravity – gravitropism. In roots, this is positive gravitropism and they grow towards gravity deeper into the soil. This helps anchor the plant, as well as allowing the roots to obtain water and mineral ions.
Do plants respond to gravity?
Gravitropism is the ability of plants to perceive and respond to the gravity vector and orient themselves accordingly. Perception of the gravity signal occurs through the movement/sedimentation of starch-filled plastids (termed statoliths) in gravity sensing cells.
How gravity is detected by plants?
Gravity perception is important to plants because they need to send their roots downwards towards water and nutrients and their shoots upwards towards light. Plants are known to detect gravity using statoliths, which are small starch-filled packets that settle at the bottom of gravity-sensing cells.
How do plants defy gravity?
Well in the leaves of a plant we have small pores called stomata. This force of transpiration pulls on the stream of water molecules, as they evaporate out of the plant. And there you have it. That is how plants defy gravity.
