Students have asked these similar questions
Since you're done with your study of plant tissues, you may now answer the questions about them
below.
1. How do meristems accomplish the production of new, mitotically healthy cells?
2. What is indeterminate growth in plants?
3. What is de-differentiation in plant cells?
You are studying a type of plant known as " rockcress" or Arabidopsis sp. You discover a mutant in which the central cell of the female gametophyte cannot be fertilized. What structure will not form in these mutant plants?
Synergids
Pollen tube
Endosperm
Egg cell
The image below represents a flower meristem viewed from above. At the time the image represents, the cells are undifferentiated, although their eventual fates are determined (e.g. carpels, etc.). The rectangles
indicate the regions of the meristem where particular genes (A, B, and C) are expressed. Note that these genes are expressed all around the circumference of the meristem at the location indicated; in other words,
gene A is active in all cells in the rings labeled sepal and petals.
Sepals
Petals
Stamens
UEn Carpels
Explain what cue the floral cells are likely using to determine the cells that will differentiate into the different parts (ie. sepal, petal, etc.) based on the given scenerio.

- Which of the following pairs of plant structure has the haploid number ofchromosomes? A. Megaspore mother cell and antipodal cells B. Egg cell and antipodal cells C. Egg cell and endosperms D. Microspore mother cell and antipodal cellsarrow_forwardMany biology labs use slides of root tips to demonstrate the stages of mitosis. Why is this a better choice than using a slide of a mature leaf?arrow_forwardEarly botanists admired ferns but found their life cycle perplexing. In the 1700s, they learned to propagate ferns by sowing what appeared to be tiny dust like “seeds” that they collected from the undersides of fronds. Despite many attempts, the botanists could not locate the pollen source, which they assumed must stimulate these “seeds” to develop. Imagine you could write to these botanists. Compose a note that explains the fern life cycle and clears up their confusion.arrow_forward
- 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?

- Which of these is a feature not present in seedless plants that have contributed to the success of seed plants on land? a. Seeds have four layers of protective tissue, the seed coat, that improve survival by providing more protection from environmental stresses. b. The reduced gametophytes of seed plants are nurtured by sporophytes and protected from stress, such as drought conditions and UV radiation. c. Seed germination is solely mediated by water during episodes of heavy rain. d. Pollen grains, with walls containing sporopollenin, deter herbivores. Three unknown non-vascular plant species were collected by Biology 3 students. Which characters BEST discriminate them from one another? 1. protonema II. special organelles III. seta IV. calyptra V. capsule VI. stalk a. I,II,III b. I,III,V c. III, IV, V d.

Enzymes inside the embryo break down nutrients during germinationarrow_forwardMatch the following plant cells and tissues with their definition: - v Collenchyma A. grouped in strands and help support young parts of the plant shoot. They have unevenly thickened primary cell walls. - v Sugar-conducting cells of the phloem B. are alive at maturity, but lack organelles. Each sieve-tube element is connected to a companion cell by plasmodesmata. Water-conducting cells of the xyleem v Sclerenchyma C. The two types of water-conducting cells, tracheids and vessel elements, are dead and lignified at maturity. - v Parenchyma D. rigid due to thick secondary walls containing lignin, dead at functional maturity and play a role in support in the plant. E. cells are flexible and provide the most diversity of functions (such as photosynthesis)arrow_forward
