Question 1

A plant hormone has the same effects in different plant tissues.

Accepted Answer

Different plant tissues may have different responses to the same plant hormone. For example, auxin promotes root development in the root tissue while it promotes shoot development in the shoot tissue.

Question 2

How might a plant communicate to another plant that it has been attacked by a herbivore? ​

Question 4

When a plant becomes infected by pathogenic bacteria or fungi, it may respond by way of a fight or flight response - a defense that cordons off an infection site surrounding it with dead cells. ​

Question 7

The most widely accepted hypothesis for gravitropism proposes that plants detect gravity much the same way animals detect gravity. ​

Accepted Answer

The hypothesis proposes that plants use specialized cells called statocytes to detect gravity, which function similarly to the otoliths in the inner ear of animals. These cells are located in specialized organs called statoliths, which are present in the root cap and shoot tip. Thus, the way plants detect gravity is analogous to how animals detect gravity.

Question 8

External cues such as increasing day length or warming after a cold snap stimulate gibberellin synthesis, which results in bolting in plants such as cabbages.

Accepted Answer

This is true. Gibberellin synthesis is stimulated by external cues such as increasing day length or warming after a cold snap, which can result in bolting in certain plants such as cabbages.

Question 9

Describe the various effects of auxins in plants. ​

Accepted Answer

The answer of Describe the various effects of auxins in...

Question 10

Tropisms explain how plants can move from place to place.

Accepted Answer

Tropisms do not explain how plants can move from place to place. Tropisms are directed growth responses of plants to environmental stimuli such as light, gravity, and touch.

Question 11

Specific cells in developing seeds and maturing fruits have receptors for ethylene, but cells in stems generally do not. ​

Accepted Answer

This statement is true. Cells in developing seeds and maturing fruits have receptors for ethylene, which aids in ripening and maturation. However, cells in stems do not typically have these receptors.
