Instructions: Look for representative specimens of herbaceous dicot and monocot stem. The external parts that can be observed are nodes, internodes, leaf scar, lenticel, and buds (axillary and terminal).
Examine and compare their external morphology by answering the questions below:
1. Why are terminal buds considered an active part of the stem?
2. Of what importance are nodes to the plant?
3. What are inter nodes and where are they located?
4. What is the function of the lenticels? Do all stems have lenticels?
5. How can you differentiate a monocot plant from a dicot plant just by looking at the stem?
6. What advantage would herbaceous stems have over woody stems?
7. What advantage would woody stems have over herbaceous stems?

- 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 floweringarrow_forwardInstructions: Try to uproot one living dicot (ex. dandelion) and monocot (ex. grass) representative plant. Observe the roots of each plant and characterize as follows: A. Type of root system B. Presence of primary root C. Presence of lateral roots D. Presence of adventitious roots Note: Indicate the name of the plant, the root system it exhibits and the parts present. Tabulate the result of your observation using the table below. Answer the related questions below. Root Characteristics Monocot Specimen (Name) Dicot Specimen (Name) Type of root system Presence of primary root Presence of lateral roots Presence of adventitious roots 1.

LEAF ADAPTATION The main function of the leaf is in the processes of photosynthesis and transpiration. Apart from these functions, leaf is sometimes adapted to perform other functions. Examples of leaf adaptations are for: a) Support, which could be seen by the presence of tendrils b) Catching insects, by having cup-liked shape of hairs sensitive to touch c) Reproduction, by having meristematic cells able to produce new shoots that will go on to become new individual plants d) Food and water storage, especially found in plants living in dry areas where water is scarce (for example succulent plants, having leaf storing food and water) e) Floatation, for plants living on the water surface, their leaves in general will have air openings on tissues (used for floating) usually found on leaf petiole f) Protection, by having leaves completely or partially modified as thorns Instruction: a) 1. Search for ONE plant species with the following leaf adaptations 2. Give their scientific names…arrow_forward
