A plant biologist discovers a new species of plant in the ashes of a recent forest fire along the sides of a steep mountain range. It is fall, and temperatures are dropping below freezing. The biologist cannot stay in the field to observe the plant. What can he infer about the plants reproductive strategy based on his recent observations? A) the plant will produce flowers because at this altitude there is sufficient sunlight B) the plant will produce comes because cones will mature into adult plants more rapidly C) the plant will produce cones because cones allow for seed dispersal through all seasons D) the plant will produce flowers because flowers can protect the seed from extreme conditions
Which of these pairs is mismatched? a. anther—produces microspores b. carpel—produces pollen c. ovule—becomes seed d. ovary—becomes fruit e. flower—is a reproductive structure
Imagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document.Unit 8 DQ Question: Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? (Editor’s note: addressing this question will provide needed background information to the ‘Introduction’ of your paper).
What is pollination? The transfer of pollen from stigma to anther The transfer of pollen from stigma to ovary The transfer of pollen from anther to stigma
In your own words - grasses are flowering plants but many do not have colorful flowers. What mechanism do they use to spread their pollen
The drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?
What is the relationship between pollination and fertilization in flowering plants? Select one: a. Fertilization precedes pollinations. b. If fertilization occurs, pollination would be unnecessary. c. Pollination brings gametophytes together so that fertilization can occur. d. Pollination easily occurs between plants of different species.
A biologist finds that a plant is being attacked by beetle larva, which eats flowers. Later that same day, she observes that the air around the plant has an unusual "chemical" odour. Next day, she sees that there are many wasps stinging the caterpillars on the flowers. Give the most likely explanation for this observation and explain the underlyingconcept clearly.
Which of the following is false? A. Oak trees have flowers B. Gymnosperms make pollen C. Ferns have seeds D. Corn plants have rubisco
And some plants as stigma becomes receptive to Polin able to facilitate a pollen tube at a different time from when the anthers ripen. How would this affect the plant reproductive strategy why would this increase diversity in the plants offspring?
Does closing of the leaves of the Makahiya plant once touched considered as thigmotropism? Why or why not?
Your present concept of plants is probably quite accurate. Most have roots, stems, leaves, and flowers. Can you name two plants that have cones rather than flowers? Can you name a plant that appears to not have leaves?
