Cell Functions and Structures in Biology

The video explains the differences between plant and animal cells, focusing on their structures and functions. It covers topics such as cell walls, chloroplasts, vacuoles, lysosomes, and mitochondria. The video also discusses photosynthesis, cytokinesis, and the role of centrioles, providing a comprehensive comparison of plant and animal cells.

What is the primary role of cells in multicellular organisms?

• To act as the basic unit of life

• To provide energy to the organism

• To transport nutrients

• To protect the organism from diseases

What is the main difference between the outermost layers of plant and animal cells?

• Animal cells have a cell wall, while plant cells have a cell membrane

• Both have cell walls

• Both have cell membranes

• Plant cells have a cell wall, while animal cells have a cell membrane

Why are plant cells capable of photosynthesis?

• They have mitochondria

• They contain chlorophyll

• They have a cell wall

• They contain lysosomes

What is the function of vacuoles in plant cells?

• To store food and waste products

• To produce energy

• To aid in cell division

• To transport nutrients

Which organelle is responsible for photosynthesis in plant cells?

• Nucleus

• Mitochondria

• Chloroplast

• Lysosome

What is the role of lysosomes in animal cells?

• To provide structural support

• To store nutrients

• To degrade unwanted materials

• To aid in photosynthesis

How does cytokinesis occur in plant cells?

• By forming a cell plate

• By binary fission

• Through budding

• Through the formation of a cleavage furrow

What is the function of centrioles in animal cells?

• To transport proteins

• To store energy

• To assist in cell division

• To aid in photosynthesis

Which cells are non-ciliated?

• Plant cells

• Neither plant nor animal cells

• Animal cells

• Both plant and animal cells

Why do plant cells have more mitochondria than animal cells?

• To store more nutrients

• To aid in cell division

• To perform photosynthesis

• To transport waste
