Ground Tissue Systems in Plants

The video tutorial covers the ground tissue system in plants, excluding epidermis and vascular tissues. It explains the differentiation into extra and intrastellar systems, focusing on the extra stellar system, which includes the hypodermis, general cortex, and endodermis. The hypodermis provides protection, the general cortex aids in photosynthesis and storage, and the endodermis acts as a barrier and storage tissue.

What is the primary function of ground tissues in plants?

• To conduct water and nutrients

• To provide structural support

• To protect against pathogens

• To occupy the major part of the plant body

Which tissues are excluded from the ground tissue system?

• Xylem and phloem

• Cortex and pith

• Parenchyma and sclerenchyma

• Epidermis and vascular tissues

How are ground tissues differentiated in dicots?

• Into epidermal and sub-epidermal layers

• Into primary and secondary tissues

• Into extra-stelar and intra-stelar systems

• Into vascular and non-vascular tissues

Why is there no differentiation of ground tissue systems in monocots?

• Because they have a continuous vascular system

• Because they lack vascular bundles

• Because their vascular bundles are scattered

• Because they have a single tissue type

What is the extra-stelar ground tissue system commonly known as?

• Endodermis

• Hypodermis

• Cortex

• Pith

What is the main function of the hypodermis in plants?

• To store nutrients

• To conduct photosynthesis

• To provide protection

• To transport water

In dicots, what is the hypodermis primarily composed of?

• Xylem

• Parenchyma

• Collenchyma

• Sclerenchyma

What is the role of the general cortex in plants?

• To store and manufacture food

• To provide structural support

• To protect against pathogens

• To conduct water

What is the innermost layer of the cortex called?

• Cortex

• Pith

• Hypodermis

• Endodermis

What is the function of the endodermis in monocots?

• To store starch grains

• To act as a barrier

• To transport nutrients

• To conduct photosynthesis
