Question 1

Which of the following statements is NOT true about the germinated pollen grain?

Accepted Answer

Fertilization occurs after the pollen tube reaches the ovule and releases the two sperm nuclei, which then fertilize the egg and the central cell nuclei. The germination of the pollen grain is only the first step in the process of fertilization, but it does not itself result in fertilization.

Question 2

Which method of asexual reproduction would be most likely to occur in a wild population of plants? This method enables the parent plant to produce multiple offspring that start to grow away from the parent plant.

Accepted Answer

The answer of Which method of asexual reproduction would be...

Question 3

As the embryo matures,

Accepted Answer

The answer of As the embryo matures,
...

Question 4

Seeds contain all of the following EXCEPT

Accepted Answer

While seeds do contain an embryo sporophyte, stored food, and a seed coat, they do not always contain sufficient water for germination. Some seeds require additional water for germination, such as those in dry environments or those with hard seed coats.

Question 5

Monocots protect their first true leaves by __________,whereas eudicots protect their first leaves by __________.

Accepted Answer

Monocots protect their first leaves by surrounding them with a sheath called a coleoptile, whereas eudicots protect their first true leaves by bending the shoot as it grows through the soil and surrounding them with a protective sheath called the coleorhiza.

Question 6

Many plants are totipotent,which means

Accepted Answer

Totipotent plants are capable of regenerating a new plant from a single cell, indicating that the cell has the genetic capability of becoming an entire plant. This property is particularly useful in plant tissue culture techniques for propagation and genetic engineering. The other options are not relevant to the concept of totipotency.

Question 7

Plants that reproduce asexually by growth of a new plant from stems or roots show vegetative propagation.

Accepted Answer

Plants that reproduce asexually through the growth of a new plant from stems or roots are using vegetative propagation.

Question 8

Double fertilization in an angiosperm produces

Accepted Answer

Double fertilization in an angiosperm produces one diploid zygote and one triploid endosperm. The sperm cell fuses with the egg cell to form a diploid zygote, while the other sperm cell fuses with two polar nuclei to form a triploid endosperm.

Question 9

All of the following statements are true about seed germination EXCEPT

Accepted Answer

Not all seeds require a period of dormancy before germinating. Some seeds can germinate immediately after they are produced.

Question 10

All of the following statements about cell suspension cultures are true EXCEPT

Accepted Answer

Cell suspension cultures are used to produce chemicals in the laboratory without the need to grow and collect large numbers of plants from the natural environment. Instead, small pieces of plant tissue or genetically modified cells are grown in a nutrient-rich liquid, allowing for high concentrations of the desired chemicals to be produced and extracted. Option B is therefore false. Options A, C, and D are true.

Question 11

The function of endosperm is to

Accepted Answer

The endosperm is a tissue inside the seed that provides nutrients to the developing embryo. These nutrients are stored in the form of starch or oils and are used by the embryo for growth and development. Without the endosperm, the embryo would not have the necessary energy to germinate and grow into a mature plant. Therefore, the function of endosperm is to provide nutrients to the embryo.

Question 12

Which of the following floral structures are present during the diploid stage of a flowering plants life cycle?

Accepted Answer

The answer of Which of the following floral structures are...

Question 13

The transfer of pollen from an anther to the stigma of a carpel is

Accepted Answer

Pollination is the transfer of pollen from an anther to the stigma of a carpel, which can occur through various means like wind, water, or animal pollinators. Germination refers to the process by which a plant seed grows into a new plant, while fertilization is the fusion of male and female gametes to form a zygote. Coevolution refers to the process of two or more species evolving in response to each other's changes over time.

Question 14

The function of fruit is to

Accepted Answer

The answer of The function of fruit is to
...

Question 15

Bee pollinated flowers

Accepted Answer

Bee pollinated flowers are predominately blue or yellow, as bees are attracted to these bright colors.

Question 16

Which of the following mechanisms is NOT as likely to disperse seeds at a great distance from the parent plant?

Accepted Answer

The answer of Which of the following mechanisms is NOT...

Question 17

Which of the following is NOT a simple fruit?

Accepted Answer

The answer of Which of the following is NOT a...

Question 18

Single plant cells can be stimulated to become a callus and then further stimulated to become a new entire plant.

Accepted Answer

This process is known as plant tissue culture and involves the use of hormones to stimulate cell growth and differentiation. The resulting callus can be further cultured to regenerate into a complete plant, often with identical genetic material to the original plant.

Question 19

Which of the following statements about fruits is NOT true?

Accepted Answer

Blackberries are examples of aggregate fruits, not simple fruits, because they form from the fusion of several ovaries that were separate in a single flower.

Question 20

In a 1977 article in Science,a botanist reported the strange case of the Tambalacoque tree (Calvaria major)of the Mauritius Islands in the Indian Ocean.All of the trees appear to be hundreds of years old and date,as seedlings,to a time before the extinction of the dodo bird.The seeds of Calvaria are very hard and apparently needed to pass through the digestive tract of the dodo bird before they would germinate.Therefore,when there were no more dodo birds,no more young Calvaria trees germinated.Luckily,foresters can artificially scarify the seeds and germinate new trees now that they know this.The relationship between the dodo bird and the Tambalacoque tree is an example of

Accepted Answer

The relationship between the dodo bird and the Tambalacoque tree is a clear example of coevolution, as the survival and reproduction of the tree depended on the seed passing through the digestive tract of the dodo for germination. This mutual dependency between the species is a characteristic of coevolution. None of the other choices (micropropagation, spontaneous dispersal, genetic engineering, and vegetative propagation) accurately describe the relationship between the dodo and the Tambalacoque tree.
