B Root cap is absent in 'Hydrophytes', In hydrophytes roots are not present or not developed properly because they have abundant water in the surrounding environment so don't need to put extra effort to obtain them. It only the root cap is replaced by the root pockets and poorly developed root hairs are present. Pistia is a hydrophytes where root pockets are present.

Explanation:
B Podostemon is a hydrophytes in which the main plant body is root. It is an aquatic plant with thread-like roots that attaches the rocks. They have a pleiotropic, dorsiventral root system.

Which part of root absorbs both water and minerals?
1 Zone of cell differentiation
2 Zone of cell formation
3 Zone of cell elongation
4 Terminal portion of roots
Explanation:
A Zone of cell differentiation, also known as the zone of maturation. Zone of cell differentiation part of root which absorbs both water and minerals because in this region root hairs are present.

Hygroscopic roots are found in
1 Bryophyllum
2 Vanda
3 Rhizophora
4 All of these
Explanation:
B Hygroscopic roots are a type roots which absorb water from the atmosphere. Hygroscopic roots occur in Vanda because it is an epiphyte which absorbs moisture from the atmosphere as its source of water. Epiphytic species of Vanda possess very large and modified aerial root systems. These aerial root system are used for food consumption and water absorption.

In a woody dicotyledonous tree, which of the following parts will mainly consist of primary tissues?
1 Stem and root
2 All parts
3 Shoot tips and root tips
4 Flowers, fruits and leaves
Explanation:
D Primary tissues are the first tissues that develop during the growth of a plant and are responsible for the primary growth of the plant. These tissues are derived from the apical meristems, which are located at the tips of the shoots and roots. The remaining tissues are called secondary tissues. A dicot stem and root undergo secondary growth and hence have some secondary tissues. Branches of a dicot tree also show secondary growth. Flowers, fruits and leaves are all made of primary tissues.
