NEET BIOLOGY

Detailed explanation-1: -Dicotyledons have a series of transport vessels running through the stem, roots, and leaves. This is known as the vascular system. In herbaceous dicots this is made up of two main types of transport vessels, the xylem and the phloem, described later in this topic.

Detailed explanation-2: -Which statement describes movement through a plant in the apoplast pathway? Water moves through the cytoplasm.

Detailed explanation-3: -Apoplast is the system of cell walls which is continuous throughout the plant except in some parts like Casparian strips in the roots. Therefore it cannot be aided by cytoplasmic streaming and cannot occur through plasmodesmata. So, the correct answer is ‘apoplast pathway is faster than the symplast pathway’

Detailed explanation-4: -The apoplast is the pathway by which water travels from the root cortex’s cell walls and intercellular space. The symplastic pathway transports water through the protoplasts of the root cortex.
