Plant Biology Concepts and Functions

The video explores the discovery of cells by Robert Hooke in 1665 and their significance in biology. It highlights the similarities and differences between plant and animal cells, focusing on organelles like the nucleus and mitochondria. Unique features of plant cells, such as chloroplasts and cell walls, are discussed. The video also delves into plant hormones, including ethylene and auxin, and their roles in plant growth. Finally, it presents the ongoing debate between cell theory and organismal theory in botany.

What is the role of vacuoles in plant cells?

• To synthesize proteins

• To transport genetic material

• To maintain pressure and store nutrients

• To perform cellular respiration

Which plant hormone is known for being a gas and is involved in fruit ripening?

• Auxin

• Gibberellin

• Ethylene

• Cytokinin

What is the function of abscisic acid in seeds?

• To enhance photosynthesis

• To stimulate seed germination
