Dicot Root Structure and Functions

The video tutorial explains the classification of plant seeds into monocots and dicots, focusing on the anatomy of a dicot root using a sunflower as an example. It details the structure and function of various root layers, including the epiblema, cortex, endodermis, pericycle, and vascular bundles. The tutorial concludes with a summary of the dicot root structure and hints at exploring monocot roots in future content.

What classification is given to plants like the sunflower based on their seed embryo?

• Monocot

• Dicot

• Tricot

• Tetracot

Which characteristic is NOT associated with the sunflower plant?

• Green slender stem

• Reticulate venation

• Woody stem

• Herbaceous nature

What is the function of the epiblema in dicot roots?

• Transport of nutrients

• Absorption and protection

• Storage of food

• Photosynthesis

What is the main function of the cortex in dicot roots?

• Photosynthesis

• Diffusion of water

• Transport of water

• Protection

Which layer in the dicot root is characterized by the presence of the Casparian strip?

• Pericycle

• Epiblema

• Endodermis

• Cortex

Which of the following is NOT a part of the dicot root's vascular bundle?

• Xylem

• Phloem

• Cortex

• Pericycle

What type of cells make up the pericycle in dicot roots?

• Thick-walled cells

• Thin-walled parenchyma cells

• Sclerenchyma cells

• Collenchyma cells

Which section of the xylem is located towards the periphery in dicot roots?

• Conjunctive tissue

• Phloem

• Protoxylem

• Metaxylem

What is the role of the conjunctive tissue in dicot roots?

• Protects the root

• Stores nutrients

• Supports photosynthesis

• Separates xylem and phloem
