Adventitious root system
None of the above
2

In dicotyledonous plants, the radicle develops into the primary root, forming a tap root system.

Which of the following statements about seeds is correct?

Dicot seeds always contain endosperm
Monocot seeds have a single cotyledon
The radicle develops into the shoot
The cotyledons are absent in all monocots
2

Monocot seeds, such as maize, have a single cotyledon called the scutellum.

Which of the following statements about inflorescence is incorrect?

Which of the following statements about root functions is correct?

Roots provide support and absorb nutrients
Roots do not store food in any plant species
Roots perform photosynthesis in all plants
Roots do not play a role in water conduction

Which of the following statements about stem modifications is incorrect?

Bulbs are modified stems used for food storage
Rhizomes grow underground
