Answer:

thigmotropism

Explanation:

Tigmotropism is the curved growth of the plant, which occurs through mechanical stimulation. In the case of the question, the stone stimulated the plant's angular growth.

When the vegetable comes into contact with any consistent object, it grows around it. A very common example of tigmotropism is that of tendrils, which grow wrapped around its support. The winding occurs by a reaction that results from a stimulus from the underside of the tendril, this reaction slows the growth of this side, while the upper side grows faster.

Which of the following statements about double fertilization are true? Select all that apply. a. One sperm fuses with an egg whi
aleksley [76]

Answer: Only options A, B, C and D are true statements

A) One sperm fuses with an egg while the other sperm fuses with the polar nuclei.

B) It results in the formation of a diploid embryo and triploid endosperm.

C) Both sperms involved in double fertilization form within the same pollen tube.

- The diploid nucleus resulting from the second fertilization undergoes meiosis to form the endosperm.

Explanation:

Double fertilization is a process that occurs in only flowering plants. It involves the following:

- A pollen grain produces TWO male gametes

- one male gamete fertilize the egg to form a zygote that is DIPLOID (with two basic sets of chromosomes)

- the second male gamete fuses with another cell named POLAR NUCLEI, to form endosperm (the food storing tissue) in the seed. The endosperm formed is TRIPLOID ( it has three sets of chromosomes), having undergone reductive division - meiosis

Thus, the options A, B, C and D are true statements
