Question
Chapter 31.3, Problem 3CC
Summary Introduction
To explain:
Would the root still respond to gravity if its root cap is removed?
Concept introduction:
Roots show a positive gravitropism which means they grow downwards, in the direction of gravity. Statoliths present in certain cells of the root cap help in this.

Over time, Mélanie grew older, and eventually moved out of her parent's house. Now, when Mélanie returns to visit her parents, the tree is much larger than it was when Mélanie was just a young child, but her swing is still hangingg at approximately the same height. Using concepts and terms related to plant growth seen in class, briefly explain how this phenomenon is possible. Tenarrow_forward

- B. 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.

Grass Parallel • Fibrous roots Oak Reticulate Таp гoot Swati observed a strange plant in her garden. She saw that its leaves had parallel venation. Which of the following is most likely to be true about the plant, based on the available data? A. It is probably an aloe vera plant. B. It probably has fibrous roots. C. It probably does not bear fruits. It will probably grow into a tall tree.

And place these structures in the order that water passes through them during transpiration: endodermis, root cortex, root hair, spongy mesophyll, stomata, and xylem. -Thank you!arrow_forward
- Given that (a) xylem is located toward the upper epidermis in leaf veins and phloem is located toward the lower epidermis and (b) the vascular tissue of a leaf is continuous with that of the stem, suggest one possible arrangement of vascular tissues in the stem that might account for the arrangement of vascular tissue in the leaf.arrow_forwardFor water transport to proceed, the water potential of the leaves must be lower than the water potential of the roots.
