Question

Differentiate between
1) Tap root and Fibrous root
2) Simple leaf and compound leaf.
My name is Shanmitha Neelima of class 6th
studying in Saint Francis School, Madhurawada, Visakhapatnam.​

Answer 1

Answer:

1.Tap Root Fibrous Root

Primary root

Presence of a one large and long root One large, long root is absent

Level of penetration into soil

Deeply penetrates Does not penetrate deeply

Differentiation of the primary root

Taproot is the differentiated primary root, which later emerges as the centre of the root system Fibrous root is notthe differentiated primary root and is eliminated in later stages

Develops from the stem?

No Yes

Lateral roots

Develop from main root Absent

ExampleDicot plants Monocot plants

Presence in gymnosperms

Yes No

Presence in grass

No Yes

Role as a storage structure

Can store in some cases Does not store

Holding on to soil particles

Formation of a net not observed in order to hold soil particles Forms a network, there by holding soil particles together at the surface

2.The difference primarily between simple and compound leaves is that in simple leaves there is a single leaf blade and depression that do not split the leaf blade, whereas, in compound leaves, the depression is deep such that it splits the leaf blades into leaflets.

Answer 2

1) i.The main root (primary root) with other minor side roots, which grow deep into the soil is called Taproot.

While the fine, thick hairs like structure, that spread sideways in all the directions is called Fibrous or Adventitious root.

ii.Taproot arises from the radicle (embryonic part) of the plants, but the Fibrous root grows from the stem and leaves rather from the radicle.

2)Simple Leaves. vs compound Leaves (The first point is for simple Leaves and other for compound Leaves)

What it means.

1. Leaves in which the leaf blade is undifferentiated into lobes
2. Leaves which show proper differentiation of lamina or leaf blade into leaflets

Leaf arrangement

1. Acropetal succession
2. Acropetal succession type of arrangement of leaflets is not observed

Blades

1. Single blades
2. Small leaflets having separate leaf blades

Axillary buds

1. Axil buds are observed
2. Buds are observed in the leaf axil. However, every leaflet does not possess axil

Stipules

1. Present at the base of the leaf
2. Present at the base of the leaf, absent in other additional structures

Lamina-splitting

1. No division
2. Lamina split into more than two leaflets that arise either at the petiole tip or on the side of a rachis

Observed in

1. Guava, trees of black cherry, black gum trees
2. Neem, Rose, Buckeye, Shame plant.
