Characteristics of Living Organisms

The video tutorial explores the classification of organisms into six kingdoms based on cell complexity, ability to produce food, and cellular structure. It delves into the characteristics of prokaryotes, including archaea and eubacteria, and their adaptations to extreme environments. The tutorial also covers eukaryotic cells, highlighting their complexity and organelles. Additionally, it discusses fungi and protists, emphasizing their unique features. The video concludes with a summary of the key points discussed.

What is one of the criteria used to classify organisms into kingdoms?

• Color of the organism

• Cell complexity

• Size of the organism

• Habitat of the organism

Which of the following is true about prokaryotic cells?

• They have a nucleus

• They lack organelles

• They are mostly multicellular

• They reproduce sexually

Archaea bacteria are known for their ability to:

• Photosynthesize

• Live in extreme environments

• Produce oxygen

• Form complex multicellular structures

What distinguishes eukaryotic cells from prokaryotic cells?

• Presence of a cell wall

• Lack of DNA

• Presence of a nucleus

• Ability to reproduce asexually

Which of the following is a characteristic of plant cells?

• They are heterotrophic

• They lack a cell wall

• They are autotrophic

• They are unicellular

What does the term 'autotrophic' mean?

• Organisms that live in water

• Organisms that consume other organisms for food

• Organisms that produce their own food

• Organisms that are multicellular

Fungi are similar to plants in that they:

• Have a cell wall

• Are unicellular

• Are autotrophic

• Photosynthesize

Which of the following is a characteristic of protists?

• They cannot move

• They are prokaryotic

• They have a defined nucleus

• They are all multicellular

What is the primary method of movement for a paramecium?

• Tentacles

• Flagella

• Cilia

• Pseudopodia

Why do protists have their own kingdom?

• They cannot photosynthesize

• They are prokaryotic

• They are similar to both plants and animals

• They are all multicellular
