- Ground tissue in monocot stems performs the same functions as _______________ and _______________ in herbaceous eudicot stems. (a) phloem; xylem (b) cork cambium; vascular cambium (c) epidermis; periderm (d) primary xylem; secondary xylem (e) cortex; pithPlace the letter of the definition in the box next to its correct term Primary growth A. tissue for protection; prevents water loss Vascular cambium B. tissue that transports sugars up & down the plant Ground tissue C. creates secondary xylem & phloem Xylem D. tissue for metabolism, storage & support Bark E. Consists of cork, cork cambium & secondary phloem Dermal tissue F. tissue that transports water from roots to stems Phloem G. comes from the apical meristemChoose the incorrect statement: a. Fusiform and ray initials are formed by the vascular cambium. b. The cork cambium produces the periderm layer, a thicker tougher outer layer that replaces the epidermis. c. Wood is composed of secondary xylem. d. The vascular cambium separates the xylem on the outside of the stem and the phloem on the inside.
- Why is the secondary xylem and phloem always to either side of the vascular cambium and is the primary xylem pushed inwardly by the secondary tissues? How about the primary phloem, cortex and epidermis, are they pushed outward by the secondary tissues?Which meristem is correctly matched with its location and a type of derivative cells? Answers are in the form: meristem --> location --> tissue a. procambium – between xylem and phloem – periderm b. ground meristem – root tip – primary xylem c. apical meristem – between xylem and phloem - ground d. protoderm – shoot tip – epidermis e. procambium – root tip – groundProvide your own drawing of the Aristolochia (birthwort) stem cross-section.

- Tissues in a carrot root, make a simple sketch and label the tissues. The outermost covering of the cylinder( the skin of the carrot root) is made up of dermal tissue, particularly the periderm. Beneath the periderm is a layer called the cortex which is made up of parenchyma, a type of ground tissue. Underneath the cortex is vascular cylinder which contains the ploem(the outer layer of the cylinder) and the xylem (the central core of the cylinder, the lightly colored part). Between the ploem and the xylem where the vascular cambium is located (a layer that is only one cell thick) a lateral meristematic tissue. plsssss help me sketch this and label it, thank you.What would be the consequence of removing the Casparian strip? a. Water and mineral nutrients would not be able to reach the xylem. b. There would be less selectivity as to what passed into the xylem. c. Water and mineral nutrients would be lost from the xylem back into the soil. d. Water and mineral nutrients would no longer be able to pass through the cell walls of the endodermis.A plant that you are studying has sluggish wound healing abilities as well as an inability to store significant food reserves. You would like to enhance its ability to store food reserves. If you could enhance the growth of a tissue to improve this property, which tissue would you enhance? -Lateral meristem. -Periderm. -Parenchyma of the stem cortex. -Root apical meristem.
- Choose the incorrect statement: a. Bundle sheath cells surround the vascular bundles in both eudicots and monocots. b. Phloem sieve elements contain a higher concentration of amino acids than xylem vessels. c. Phloem sieve elements and xylem tracheary elements are similar at maturity because they are both dead. d. Root hairs are the primary cell type that absorbs water in roots.Which of the following statements are true for root endodermis?I. Endodermal cells constitute the innermost layer of root cortex and surrond the vascular cylinder (xylem and phloem). II. Endodermal wall is covered with waxy layer of casparian strip which blocks apoplastic transfer of minerals.III. Due to presence of casparian strip, water and minerals can only eneter the vascular cylinder if they will be able to cross the plasma membrane of an endodermal cell.Which of the following slides should be focused on the microscope if you want to observe primary xylem and primary phloem tissues? a cross-section of an old acacia stemb epidermal section of a leafc cross-section of a monocot stemd L-section of the onion root tip
