hytochrome, plays an important role in flowering in many plants.  It can also be used to determine when lettuce seeds germinate (shown in the figure below What is phytochrome likely doing in the lettuce seeds?        Activating abscisic acid production     Activating inhibitors of germination     Inhibiting gibberellin synthesis     Turning on germination-related genes

If a farmer wanted less tightly packed clusters of grapes, he would most likely spray the immature bunches with which of the following hormones?     cytokinins     gibberellins     auxin     abscisic acid

Illumination with red light but not far-red light will generate the Pfr form of phytochrome True False

Growers often wrap potted plants in plastic sleeves prior to shipping. If plants remain in these sleeves too long, their leaves curl and fall off. Imagine you are working at a garden center and have been asked to make a presentation to a local garden club.  how can growers avoid problems for example when it comes to plastic sleeves how can we fix it

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. Interpret the figure by filling in the following table: I've numbered each row to help with writing the answer below. Determined by the activity of which gene(s) - A,B,C? Organ Carpel 1. Stamen 2. Petal 3 Sepal 4 Sepals Petals Stamens Bn Carpels

Plants and animals usually battle each other; describe why and how this occurs. Once animal-pollinated flowers evolved, a new type of plant–animal interaction was possible; describe it. How is it possible for a mutation in aplant to be beneficial for both the plant and for an animal?

Can you answer all the parts to this question please  In shoot apical meristems, the peripheral zone (PZ) genetic program maintains indeterminacy and allows lateral primordia initiation. (a) Explain how the PZ genetic program control (1) meristem maintenance, (2) organ separation, and (3) organ differentiation/leaf primordia outgrowth using the following keywords: KNOX genes, cytokinins, gibberellin, auxin, CUC, and AS1.  (b) Explain how this genetic program is used in the formation of compound leaves.  (c) Please use KNOX PZ genetic module as an example to explain process homology during compound leaf evolution.

Please help this is hw and I want to know why I'm wrong Why do many plants use pathways that detect light to regulate their flowering? Selected Answer: This allows plants to link flowering to temperature, which corresponds to the season when conditions are optimal Answers: This allows plants to link flowering to day length, which corresponds to the season when conditions are optimal   Flower petals carry out high levels of photosynthesis and require high light conditions   This allows plants to link flowering to temperature, which corresponds to the season when conditions are optimal   A minimum amount of light is always necessary for flowering
