Plant Biology Concepts and Characteristics

The video introduces Kingdom Plantae, highlighting that plants are chlorophyll-containing multicellular eukaryotes with cell walls made of cellulose. Most plants are autotrophic, producing their own food, while some are partially heterotrophic, like insectivorous plants (e.g., bladderwort, venus flytrap) and parasitic plants (e.g., cuscuta). The plant life cycle involves alternation of generations, with both haploid gametophytic and diploid saprophytic phases. Further details will be covered in the next chapter.

What is a defining feature of the cell walls in Kingdom Plantae?

• They are made of cellulose.

• They are made of keratin.

• They are made of chitin.

• They are made of lignin.
