Summary Introduction
Introduction:
The roots are mostly underground and help in anchoring the plant to the soil, absorb water and minerals and transport them upwards. It is also involved in storing products of photosynthesis. The roots are modified to absorb moisture and exchange gases.

- Leaves can grow anywhere on a stem. True False All of the shoot tissues are generated by the shoot meristems. True False In seed plants, lateral roots don't form during germination. True Falsearrow_forwardWhat is the difference between the apical meristem and lateral meristem? shoot apical meristems lateral meristems root apical meristems Apical meristemic tissue is responsible for primary growth at the root and shoot tips. Lateral meristemic tissue is responsible for secondary growth with an increase in diameter of the stem. Apical meristemic tissue is responsible for secondary growth with an increase in diameter of the stem. Lateral meristemic tissue is responsible for primary growth at the root and shoot tips. Lateral meristematic tissue is only found in annual plants. O Apical meristemic tissue is only found in woody plants.arrow_forwardIn a germinating seed, the downward growth of roots and upward growth of stems are the plant’s responses to gravity. Which statement best describes this phenomenon? * downward growth of roots – positive response to gravity ; upward growth of stems – negative response to gravity downward growth of roots – negative response to gravity ; upward growth of stems – positive response to gravity downward growth of roots – positive response to gravity ; upward growth of stems – positive response to gravity No answer downward growth of roots – negative response to gravity; upward growth of stems – negative response to gravityarrow_forward
