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.

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.
