The growth rate of geometric growth is called relative growth rate or ‘efficiency index’. �Zq�B�=Q��B*��d���@Zo#\��437P��q�?�4�hYo6!��P� • All cells of a plant develops from the zygote. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. It is important to understand how these factors affect plant growth and development. Development in plants is actually a sum of two processes: growth and differentiation. We believe that education is a fundamental right should be made available to each and every child. Effect of Light and Temperature on Plants Calcium: a central regulator of plant growth and development Plant Cell. Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. while the other daughter cell enlarges and differentiates. Apical meristems are found at the apex, or tip, of roots and buds, allowing roots and stems to grow in length and leaves and flowers to differentiate. The development of flowers in response to a period of low temperature is called The presence of meristems is plants in plants helps them retain the capacity to grow • Development is the sum of two processes: growth and differentiation.
