Cell Functions and Organelles in Action

Mr. Veve's lesson covers cell processes and organelles, focusing on how organelles support cell functions, maintain homeostasis, synthesize new molecules, and convert energy. The video explains the roles of the cytoskeleton, cell wall, cytoplasm, cell membrane, vacuole, lysosomes, ribosomes, endoplasmic reticulum, Golgi apparatus, nucleus, mitochondria, and chloroplasts. It also highlights the differences between animal and plant cells, such as the presence of chloroplasts, cell walls, and large central vacuoles in plant cells.

What is the primary role of organelles within a cell?

• To provide energy to the cell

• To carry out specialized functions

• To store genetic information

• To protect the cell from external damage

Which organelle is responsible for providing structural support and aiding in cell movement?

• Golgi apparatus

• Cytoskeleton

• Mitochondria

• Nucleus

What is the function of the cell membrane in maintaining homeostasis?

• It synthesizes proteins

• It produces energy

• It stores nutrients

• It regulates what enters and leaves the cell

How do lysosomes contribute to cellular homeostasis?

• By storing genetic material

• By digesting old material and waste

• By synthesizing new proteins

• By converting sunlight into energy

What process is involved in the synthesis of new molecules in cells?

• Cellular respiration

• Photosynthesis

• Dehydration reaction

• Hydrolysis reaction

Which organelle is known as the 'assembly line' for proteins and lipids?

• Golgi apparatus

• Ribosomes

• Endoplasmic reticulum

• Nucleus

Which organelle is considered the control center of the cell?

• Nucleus

• Mitochondria

• Endoplasmic reticulum

• Golgi apparatus

What is the primary function of mitochondria in cells?

• To synthesize proteins

• To convert food into energy

• To regulate cell division

• To store water

Which organelle is responsible for photosynthesis in plant cells?

• Chloroplasts

• Mitochondria

• Ribosomes

• Lysosomes

What is a key difference between plant and animal cells?

• Plant cells have a cell wall, animal cells do not

• Animal cells have a large central vacuole, plant cells do not

• Animal cells have chloroplasts, plant cells do not

• Plant cells have lysosomes, animal cells do not
