What does an interaction between pollen grains and its compatible stigma result in after pollination ? List two steps in sequence that follow after the process.

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Interaction Between Pollen Grains and Stigma**: When pollen grains land on a compatible stigma, a chemical interaction occurs between the pollen grain and the stigma. This interaction is crucial as it facilitates the growth of the pollen tube. 2. **Growth of the Pollen Tube**: Following the chemical interaction, the pollen tube begins to grow from the pollen grain. The pollen grain contains two types of cells: a vegetative cell and a generative cell. The contents of the generative cell move into the pollen tube as it develops. ...

In a certain experiments to measure the ratio of charge to mass of elementry particles, a surprising result was obtained in which two particle, a surprising result was obtained in which two particles moved in such a way that the distance between them always remained constant. It was also noticed that this two-particle system was isolated from all other particles and no force was acting on this system except the force between these two mases. After careful observation followed bu intensive calculation, it was deduced that velocity of these two particles was always opposite in direction and magnitude of velocity was 10^(3) ms^(-1) and 2 xx 10^(3) ms^(-1) for first and second particle, respectively, and mass of these particles were 2 xx 10^(-30) kg and 10^(-30)kg , respectively. Distance between them were 12Å(1Å = 10^(- 10)m). if the first particle is stopped for a moment and then released, the velocity of center of mass of the system just after the release will be

Read the following statements and find out the incorrect statements. a. In majority of organisms, male gamete is motile and female gamete is non-motile (stationary). b. In algae and fungi, both male and female gametes are non-motile. c. In seed plants, pollen grains are the carrier of male gametes and ovule has the egg. d. In dioecious plants, pollination facilitates trasnfer of pollen grains to the stigma. e. In monoecious animals, since male and female gametes are formed in different individuals, the organism must evolve special mechanism for gamete transfer.

Read the following statements and select the correct option. Statement 1 : In pea plant, transfer of pollen grains to the stigma is easy. Statement 2 : In cross pollinating plants, pollination does not take place.

Assertion: Continued self-pollination generation after generation results in pure line formation. Reason: By continued self-pollination, plant becomes pure or homozygous for its characters.

Keith modeled the growth over several hundred years of a tree population by estimating the number of the trees’ pollen grains per square centimeter that were deposited each year within layers of a lake’s sediment. He estimated there were 310 pollen grains per square centimeter the first year the grains were deposited, with a 1% annual increase in the number of grains per square centimeter thereafter. Which of the following functions models P(t), the number of pollen grains per square centimeter t years after the first year the grains were deposited?
