Make a sketch of the 40x leaf cross section and upload it here with the following structures labeled: upper epidermis, cuticle, stomata, guard cells, mesophyll (palisade and spongy), veins (xylem and phloem), bundle sheath, collenchyma cells, lower epidermis MacBook Proarrow_forwardExplain the reason why the roots lack the protective covering like the plant surface which has a waxy cuticle.arrow_forward
- Hi. Can u pls help me define the "Based on toughness" and "Based on location" of the stem. Not the bulleted under it, the A and B itself. Thank you STEM( Part of a plant) I. Classification A. Based on toughness -herbacious stem - woody stems B. Based on location -Aerial stems -underground stemarrow_forwardI. 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.. What is the function of the lenticels? Do all stems have lenticels? 2. How can you differentiate a monocot plant from a dicot plant just by looking at the stem? 3. What advantage would herbaceous stems have over woody stems? 4. What advantage would woody stems have over herbaceous stems? II. Compare the internal anatomy of stems of xerophytes, mesophytes, and hydrophytes. Relate differences to the nature/habit of the different plants.arrow_forwardFill in the blank.

Explain how the Casparian strip creates a barrier for substance moving through this pathway and how it is circumvented.arrow_forwardYour scheduled patrolling of com field has collected various leaves samples with symptoms stated as below. Use these symptoms to explain about the type of nutrient deficiency to your worker. (i) Burning of leaf tip and edge. (ii) Reddish purple leaf edge on lower leaves. (iii) Interveinal chlorosis. (iv) Wrinkled and unopened leaf. (v) Some of the nutrient deficiency symptoms were ohserved on new growth but some were observed at the lower leaves. How would you explain this phenomenon to your worker? (vi) What are the field guides to distinguish between biotic and abiotic causes of leaf abnormalities?arrow_forwardAbscission Zone: The Abscission Zone forms at the It facilitates leaves to The Abscission Zone is marked through a tissue layer containing the substance [spell precisely] We met this substance already: After secondary thickening has ocurred, in the and inside of organs, along the PICK ONLY ONE OPTION: 1.)

Caspari strip Central Cylinder Xylem Phloem Sclerenchyma When you compare the cross section of leaves of Poa with those of Zea, look at the vascular bundles. You see that in one taxon, the vascular bundle sheeth cells are proportionally thicker than in the other (proporional = in comparison to mesophyll and phloem cell diameters).

- What is a part of plant. (stem, roots, leaves) and can u pls define them or give a introduction to themarrow_forward. Label at least 6 tissues and/or structures the leaf cross section. Explain how the organization of the leaf tissues facilitate the function of the leaf.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
