Summary Introduction
Introduction:
Plants consist of vegetative structures- roots, leaves, and stems, and the reproductive structures- flowers and fruits. The plant organs consists of four kinds of tissues namely, epidermal tissue, meristematic tissue, vascular tissue, and ground tissue.

One of the major differences between roots and leaves is
roots have vascular tissue but leaves do not.
root cells have cell walls and leaf cells do not.
only leaves have phloem and only roots have xylem.
a waxy cuticle covers leaves but it is absent in roots.
The tip of a plant like the prairie species we grew in
class, where cells are continuously dividing and growing,
as well as the tips of the roots where cell division
continues throughout the plant's life are termed
meristems

- Plant stem cells such as those found in cambium tissues are able to -fight microbial invaders by becoming mobile and phagocytic. -produce nutrients for other cells. -remain undifferentiated but divide to produce cells that differentiate into new tissues. -exist as mature cells.arrow_forwardT/F Question Parenchyma is soft, internal plant tissue. Xylem and phloem are plant structural tissue. Periderm tissue is a type of plant epidermis in young stems and roots. Plant shoots include stems, leaves, and flowers. Monocot stems have their vascular bundles arranged in a ring pattern in the ground tissue. Eudicots have their leaf veins arranged in a parallel pattern. Photosynthesis in leaves takes place in the mesophyll layer Eudicots possess a large taproot. The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules. Plant tissues grow from meristem cells that continually divide during the growing season. Primary plant growth involves thickening of the stems and roots. Plants can undergo asexual reproduction without cross-pollination. The fertilization process in plants is a double fertilization process. Over 1/3 of the U.S. food supply comes from the cross-pollination…arrow_forwardDiagram 1: Cross Section of a leaf-cells and structures. cuticle -upper epidermis palisade layer chloroplasts vascular bundle spongy mesophyll -intercellular chamber -lower epidermis stoma A possible explanation to explain the presence of the stoma structure would be that it stores extra water the leaf does not need. allows a passageway for gasses to enter and exit the leaf makes sugar needed by the cells.
