Meristem culture helps in developing which of the following?a) Tall plantsb) Disease resistant plantsc) Virus free plantsd) Hybrid plants
Let's talk about the "apriori pruning principle," if you like. Could you give me an example of this?
Which of the following explains why pea plants in high soil nitrogen conditions have
so few rhizobial nodules on their roots?
When there is already high soil nitrogen there is a very large cost to having
rhizobial nodules.
The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the
soil, so when there is already high soil nitrogen there is no advantage for the pea
plant to expend the extra energy housing the rhizobia.
The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the
soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia
to keep the nitrogen for itself.
When there is already high soil nitrogen there is no benefit to the plant to
having rhizobial nodules, which can rob the plant of the high nitrogen supplies
so that the rhizobia bacteria do not have to fix the nitrogen themselves.

- While exploring a forest, you come upon a plant that you haven't seen before. You dig it up and take it back to your lab for further inspection. Back at the lab, you observe the characteristic structure of the plant and make some notes. Then, you carefully dissect the stems and leaves and look at the tissue under the microscope. Finally, you are able to determine the type of plant it is. Use the notes below to identify the class to which this plant belongs. Notes on physical characteristics of the specimen: the plant has no leaves or roots, but has hair-like rhizomes which anchors it in the soil the stems are highly branched sporangia are present at the ends of each stem dissection of the stem shows the presence of vascular tissue in the form of a xylem and phloemarrow_forwardWhich of the following comparisons between the moss life cycle and fern life cycle are correct? A) Mosses have flagellated sperm that need water to reach the female gamete, while the sperm of ferns are unflagellated and are not dependent on water.B) The sporophyte generation is smaller than the gametophyte generation in mosses, but the sporophyte generation is much larger than the gametophyte generation in ferns.C) The spores are produced in capsules on stalks in mosses but in small structures called sori on the underside of leaves in ferns.D) The gametes are produced in gametangia in mosses but in specialized structures on the underside of leaves in ferns.E) Both kinds of plants depend on wind for dispersal of spores.arrow_forwardWhich of the following statements is accurate? a) All plants have identical sporangia, all producing the same type of spores b) Plants have an embryo that is protected inside (and nourished by) the gametophyte c) Gametangia produce gametes by meiosis whereas sporangia produce spores by mitosis d) Gametangia always produce haploid gametes whereas sporangia produce diploid spores e) Gametangia are multicellular structures whereas sporangia are unicellular structuresarrow_forward

Identify the structures that represent these two stages in its life cycle. ii) Explain why the alternation of generation in Anthrophytes must be different from that of the Bryophytes.(-arrow_forwardClassify the pictured organism.

You want to investigate the role that these variables play in plant growth. You decide to test the substrate and see if changing substrate mixes will affect plant growth. Match the following experimental components with their descriptions. Experimental Components: ( Experimental Variable, Dependent Variable, Control Condition, Independent Variabe, A Confounding Variable That Must Be Held Constant) 1. type of substrate used: 2. growth resulting from substrate type 3. amount of water needed in all plants 4. substrate that is changed during the experiment 5. substrate that is not changed during the experimentarrow_forward

Two groups of plants are grown from seed in identical soil types, exposed to identical light conditions, and given the same nutrients. Group A is in a quiet atmosphere.

The scientist measures the plants in both groups each day and records the data. In experimental design, Group A is known as.* experimental group control group non-experimental group O quasi-experimental grouparrow_forward

She will be using onions as a special ingredient and garnish in her recipe. She then planted onions in two soil treatments labelled as ANGAT and UNITY. After a week, SimpLENI noticed that her onions in ANGAT increased in number compared to that of onions in UNITY. She then hypothesized that the soil treatments affected the cellular division in the roots of onions contributing to the difference in yield. To prove this, SimpLENI prepared longitudinal sections of onion root tips. Support SimpLENI in her experiment and win the competition by answering the following questions:arrow_forward
