Monocots, such as grasses, usually have ____ root systems
A
simple, straight
B
taproot
C
fibrous
D
aerial
Explanation: 

Detailed explanation-1: -Grasses and other monocotyledons (angiosperms with a single seed leaf) have a fibrous root system, characterized by a mass of roots of about equal diameter. This network of roots does not arise as branches of the primary root but consists of many branching roots that emerge from the base of the stem.

Detailed explanation-2: -Monocot roots are fibrous, meaning they form a wide network of thin roots that originate from the stem and stay close to the surface of the soil. In contrast, dicots have “taproots, ” meaning they form a single thick root that grows deep into the soil and has smaller, lateral branches.

Detailed explanation-3: -Grasses are monocots and have a fibrous root system. They have a hollow, thin cylindrical stem and the leaves have parallel venation.

Detailed explanation-4: -Monocots have a fibrous root system. This means that when you look at the roots of these plants, they have many roots that branch right from the stem. This system is quite advantageous for these plants because it increases their surface area within the soil in order to collect water as well as nutrients.

Detailed explanation-5: -Dicot plants have tap root system and fibrous root system is seen in monocots. Taproots have a main central root upon which, small, lateral roots called root hairs are attached.
