Life Processes and Organism Structure

The video explains the essential life processes that define living organisms, including movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. It introduces the concept of cells as the basic building blocks of life, distinguishing between unicellular and multicellular organisms. The video further explores how similar cells form tissues, which then form organs and systems, ultimately creating a complete organism. Examples include muscle cells forming muscle tissue and root hair cells forming root tissue.

Which of the following is NOT considered a life process of living organisms?

• Movement

• Respiration

• Photosynthesis

• Excretion

What is the primary function of respiration in living organisms?

• To obtain energy

• To excrete waste

• To grow

• To reproduce

Which of the following organisms is an example of a unicellular organism?

• Tree

• Dog

• Yeast

• Human

What is the main difference between unicellular and multicellular organisms?

• Unicellular organisms do not perform life processes, while multicellular organisms do.

• Unicellular organisms are always plants, while multicellular organisms are always animals.

• Unicellular organisms have one cell, while multicellular organisms have multiple cells.

• Unicellular organisms have multiple cells, while multicellular organisms have one cell.

In animals and plants, what do similar cells form?

• Organs

• Systems

• Organisms

• Tissues

Which of the following is an example of an organ formed by muscle tissue?

• Kidney

• Lung

• Brain

• Heart

What system is formed by root hair cells in plants?

• Digestive system

• Transport system

• Respiratory system

• Nervous system

How do different systems in the body contribute to the formation of an organism?

• They only function during certain times of the day.

• They compete with each other for resources.

• They work independently without interaction.

• They interact and work together to form a complete organism.
