Plant Growth and Development Concepts

The video tutorial explains the differences between growth and development in plants, focusing on characteristics, nature, quantitative and qualitative changes, and causes. Growth is associated with size increase and is irreversible, while development involves maturity and is reversible. The video also includes quizzes to reinforce learning.

What is the primary characteristic of growth in plants?

• Addition of new structures

• Increase in size

• Development of new functions

• Change in color

Which process is associated with the development in plants?

• Loss of old leaves

• Reduction in plant height

• Formation of new structures

• Increase in leaf size

How is growth in plants described in terms of its nature?

• Reversible

• Irreversible

• Temporary

• Cyclic

What is a reversible process in plant development?

• Stem elongation

• Leaf expansion

• Flower blooming

• Leaf regrowth after plucking

How can the changes in growth be measured?

• Qualitatively

• Quantitatively

• Visually

• Subjectively

What type of change is observed in plant development?

• Numerical

• Quantitative

• Qualitative

• Statistical

What causes growth in plants?

• Water intake

• Nutrient absorption

• Cell division and enlargement

• Cell differentiation

What leads to the development of specific plant functions?

• Cell differentiation

• Cell division

• Nutrient uptake

• Water transport

Which example involves both growth and development?
