- It is the superficial tissue in a herbaceous stems. ______________________ The tissue of the stem cortex that primarily function for storage. __________________________________ Stem cortical layer present only in the underground stem. _____________________________________________________arrow_forwardPlants provide a wide range of benefits to both the ecosystems in which they live, as well as to humans. Identify and describe 1) a benefit to the ecosystem, and 2) a benefit to humans specifically (1-2 sentence per function). Be sure to include information regarding why these functions are important or what impact they have.arrow_forwardThe interior tissues of a leaf are called mesophyll. In most leaves, there is an upper layer of columnar cells called the _________________________________________ and a lower portion of _____________ ______________ open, loose aerenchyma. “Botany and Beyond: Leaf Structure, Layer by Layer,” the upper layer of columnar cells, but they do not look columnar. Why not? the box shows the lower aerenchymatous layer. Can you tell what the shape of the intercellular spaces is from this two-dimensional micrograph?arrow_forward

In rye, a single plant has been found to have __________________ lateral roots with ________________ km of root length and a surface area of _________________ m2.

Imagine a plant adapted to a desert and one adapted to a rain forest. Do you think that the leaves of one might be different from the leaves of the other? That one might have enlarged roots that can store water and the other would not need these? Would it be easier to understand a plant’s anatomy and physiology, all its biology, if we also know the type of habitat to which it is adapted?arrow_forwardOpenings in the plant body to allow for gas exchange are termed palisade cells collenchyma stomata spiraclesarrow_forward

Describe how one may test for the presence of starch on a piece of potato tissue. iii) Give TWO characteristics of monocotyledonous plants. d. The transition of plants from an aquatic environment to a terrestrial one has broughtabout many evolutionary adaptations for plants to survive on land. Give ONE adaptationfor each of the following divisions:i) Mosses: ii) Gymnosperms.arrow_forwardThis is a required question Which statement describes the role of flowers in plant survival? Flowers can absorb carbon dioxide for sugar production. Flowers produce oxygen through cellular respiration. Flowers contain cells that carry out photosynthesis. Flowers contain cells that produce gametes(sex cells). The diagram below represents a flower, the reproductive struc plants.
