The leaves of a maple tree vary in size depending on the location of the leaves on the tree. Those growing at the outer region of the tree tend to be smaller than those growing closer to the trunk of the tree. This allows leaves that are growing in the shade to have a larger surface area. This is an example of.

RESPONSE TO ENVIRONMENTAL FACTOR

Explanation: Leaves just like other parts of a plant respond to environmental factors inorder to adapt well to growth and development of the host tree as well as to contribute to reproductive processes and photosynthesis.

Leaves growing at the outer region of the tree are known as SUN LEAVES and they are found at the top of trees,they are thicker and smaller this is because they receive enough sunlight and air.

The leaves growing closer to the trunk of trees are known as SHADE LEAVES,they are also found at the button of the trees and they tend to be larger in surface area and thinner and they have more chlorophyll because the shade they receive from the sun leaves helps them to maintain/retain their green color pigment.

La hoja (del latín fŏlĭum, fŏlĭi) es el órgano vegetativo y generalmente aplanado de las plantas vasculares, especializado principalmente para realizar la fotosíntesis. La morfología y la anatomía de los tallos y de las hojas están estrechamente relacionadas y, en conjunto, ambos órganos constituyen el vástago de la planta. Las hojas típicas —también llamadas nomófilos— no son las únicas que se desarrollan durante el ciclo de vida de una planta. Desde la germinación se suceden distintos tipos de hojas —cotiledones, hojas primordiales, prófilos, brácteas y antófilos en las flores— con formas y funciones muy diferentes entre sí. Un nomófilo consta usualmente de una lámina aplanada, de un tallo corto —el pecíolo— que une la lámina al tallo y, en su base, de un par de apéndices —las estípulas—. La presencia o ausencia de estos elementos y la extrema diversidad de formas de cada uno de ellos ha generado un rico vocabulario para categorizar la multiplicidad de tipos de hojas que presentan las plantas vasculares, cuya descripción se denomina morfología foliar

Explanation:

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

that is wrong, its not thymus.
