Question

If a plant has a fibrous root, what type of venation are its leaves likely to have?

Answer 1

Hint: The fibrous root system is common in monocotyledons. It is opposite to the tap root system. The fibrous root system is sometimes referred to as, Adventitious root system. The fibrous root grows downwards into the soil it further branches off sideways through the soil.

Complete answer: Features of monocots:
1. Monocot plants have embryos with single cotyledon thus called monocotyledons, here mono stands for single.
2. Monocot plants are mostly herbaceous and are occasionally woody.
3. In Monocots pollen has a single slit or single aperture.
4. Floral parts are trimerous i.e. parts in threes or are multiples of three.
5. Leaves are oblong and are linear.
6. The petiole is covered with a sheet.
7. Leaves have parallel venation.
8. A stipule is absent.
9. Monocots have a fibrous root system.
10. Secondary growth is absent in monocot plants and is present in dicot plants.
11. Vascular bundle in monocot plants is a scattered vascular bundle.
12. Examples of monocot plants are; Grasses, Lilies, Banana, Bamboo, Palm tree, Orchids, Pineapple, Onion, Garlic, sugarcane.
So, plants with fibrous roots have parallel venation.

Note: Venation is the pattern in which veins are arranged on a leaf blade or leaf sheath. Venation in monocot plants is parallel venation and venation in dicots is reticulate venation. Leaf veins connect the blade of the leaf to the petiole. Leaf veins have two primary vascular tissues they are xylem and phloem. Xylem transports water and soluble ions into the leaf and phloem transport carbohydrates from the leaf to the rest of the plant parts.
