Topic 1 & 2 TEST

Reproduction in Plants and Animals and Growth of Organisms

QuestionAnswer
What is the process by which an organism produces offspring or young? Reproduction
What is any factor either abiotic or biotic that influences a living organism? Pollination
What are things that result in the specific DNA code of a specific individual? Genetic Factor
What is the process of fertilizing plants or flowers by transferring genetic material? Environmental Factor
What is fertilizer used for? To help plants grow
Students treated a population of bean plants with fertilizer. These observations lend support to which of the following conclusions? Fertilizer can affect the growth of bean plants.
The Articum lappa plant produces prickly burrs that grow on the ends of the stems. These burrs can easily catch on the fur of animals. This plant structure most likely benefits the plant in which of the following ways? Helps the plant transport its seeds.
Genetic material is all plants are ___ the same. Not
Male widow birds (Euplectus progne) have very long tail feathers. What evidence would support the claim that these tails are used by the birds to attract mates and lead to reproductive success? The males with the longest tail feathers produce the greatest number of offspring.
Students visiting the zoo observe a male peacock spreading his feathers in the presence of a female peahen. This behavior most likely helps the peacock do what? Attract a mate.
Which of the following procedures would provide the best data to test the effect of daylight hours on the number of blooms on rose bushes? Collect data on the number of blooms on rose bushes all grown under identical conditions, except with different hours of daylight.
Which of the following plant adaptations allows plants to use animals to transport their seeds to new locations? Sweet Fruit
Students planted 100 seeds in two different plots of land on the same day. Both plots of land measured 10 square meters. They recorded data for one year. The plants in seed group 2 are taller. Why are these plants taller? Genetic factors of the plants
What specialized plant structures increase the probability of successful reproduction? Specialized plant structures such as brightly colored petals to attract potential pollinators and extended stamens that require animals to brush against the plants in order to receive nectar.
The songs of birds are part of a ritual to attract potential partners of their own species. The song presents specific patterns recognized only by members of the same species. How does this help birds reproduce? Songs that are only recognized by the same species of bird represent a mechanism of reproductive isolation, an advantage in reproductive success.
What affects the growth of adult plants? Genetic factors as well as local conditions affect the growth of adult plants.
Describe why flowers in a pot will bend toward a window. Plants require the Sun’s radiant energy to be able to make their own food. Plants will bend toward a light source in order to absorb as much light as possible.
What do tree rings represent? Each year adds new growth to a tree in the form of a tree ring.
What does tree growth depend on? Tree growth depends upon local environmental conditions.
What makes plants grow toward sun? Light
What makes plants grow on a tree? Touch
What makes a plant's roots grow downward? Gravity
What makes a male (boy) peacock stand out? Brightly colored, large feathers
What is a peahen? A female peafowl
What color are peahens? Brown or grey
