- 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?arrow_forwardVISUAL SKILLS Which mature seed lacks an endosperm?What happened to it?arrow_forwardYour concept map must include details about the following topics: types of stimuli plants respond to, 3 stages of cell signaling, 6 major plant hormones Six main types: Auxins, abscisic acid, cytokinins, ethylene gibberellin, and brassinosteroids. and their functions, phytochrome, plant responses to light, statocytes, statoliths, plant responses to gravity, plant responses to touch, plant defenses against herbivores, plant defenses against pathogens (hypersensitive response and systemic acquired resistance)arrow_forward

The xylem tissue in the primary plant body is called primary xylem and is produced specifically by the _____________ (meristem). 2. The large, highly vascularized leaves that function for photosynthesis in most vascular plants is called _____________, while the spore bearing leaves is called _________. 3. In the non vascular plants, the plant structure that functions for photosynthesis is the _______________, while the part that anchors the plant to the ground is the ________. 4.

If provided actual flowers or images of flowers, can you determine if they are from a monocot or dicot plant (based on the expected patterns of petals) Can you identify key parts of a flower (sepals, petals, stamen, pistil, anther, filament, stigma, style, ovary, ovules) Difference between perfect & imperfect flowers? If a plant produces flowers, is it a gymnosperm or angiosperm? What are the names and functions of the 2 cells within a pollen grain? During double fertilization, what 2 structures are fertilized? What does each fertilized structure become?arrow_forwardExercise II Bryophyta: The Mosses Examine with the dissecting microscope the mosses that are available. The "leafy" plants are the gametophytes and any elongated structures growing above them are the sporophytes. (See text Figure 16-27, page 385.) 15. Label the following in Figure 5 below: spores, zygote, protonema, gametophyte, meiosis, female, male, sporophyte, archegonia, sperm, sporangium.

Moss Life Cycle (drawn by Stephanie Preising, SCSU '20) Obtain a gametophyte and observe its symmetry, its leaf like structures, its axis (pseudo- stem), and is rhizoids. Some species of mosses are unisexual; others are bisexual. The moss gametophyte originates as budlike structures that develop from a protonema (plural: protonemata), a system of branching filaments derived from a germinating spore.arrow_forward
- 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. Which root system gives better anchorage and why? 2. List down five general features of roots you can recognize in both of your specimens.arrow_forwardB. 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

Plant biologists recognize different types of fruit, 11 of which are described in the table below. Dried fruits can be further classified as indehiscent (the fruit/pod does not split open when ripe) or dehiscent (fruits/pods split open when mature). 51 Examine the provided examples of fruits. Fruit Type Description Example Category Simple fruits Ovary wall and seed coat are fused, one seed; seed is attached at only one point to the ovary wall Sunflower seeds Achene Ovary wall is thin and fully fused to the seed at all points; one seed.
