Cell Structures and Functions in Living Organisms

The video explains that all living organisms are made of cells, with unicellular organisms having one cell and multicellular organisms having many specialized cells. It describes the structure and function of animal cells, including the cell membrane, nucleus, cytoplasm, ribosomes, and mitochondria. The video also covers plant cells, highlighting differences such as the cell wall, vacuole, and chloroplasts, which are involved in photosynthesis.

What is the primary difference between unicellular and multicellular organisms?

• Multicellular organisms do not have organelles.

• Unicellular organisms have multiple cells.

• Multicellular organisms consist of a single cell.

• Unicellular organisms consist of a single cell.

What is the function of the cell membrane in animal cells?

• It provides energy to the cell.

• It is responsible for protein synthesis.

• It controls what enters and exits the cell.

• It stores genetic material.

Where is the genetic material stored in an animal cell?

• In the mitochondria

• In the ribosomes

• In the cytoplasm

• In the nucleus

What is the primary role of ribosomes in a cell?

• To synthesize proteins

• To store energy

• To control cell division

• To transport nutrients

What process occurs in the mitochondria?

• Photosynthesis

• Protein synthesis

• Aerobic respiration

• Cell division

What is the function of the cell wall in plant cells?

• To store genetic material

• To control what enters and exits the cell

• To provide structure and support

• To synthesize proteins

What is the role of the vacuole in plant cells?

• To provide energy

• To maintain cell turgidity

• To store genetic material

• To synthesize proteins

Which organelle is responsible for photosynthesis in plant cells?

What are the three extra organelles found in plant cells compared to animal cells?

• Cell wall, vacuole, chloroplast

• Ribosome, mitochondria, chloroplast

• Cell membrane, cytoplasm, nucleus

• Nucleus, ribosome, mitochondria
