Cell Membrane and Cell Wall Concepts

The video tutorial covers a BZ2020 science practical, focusing on labeling animal and plant cells, identifying plant cells, and tabulating differences between cell membrane and cell wall. It provides detailed explanations of cell parts and offers additional information and exam tips.

What is the primary focus of the BZ2020 science practical?

• Analyzing weather patterns

• Exploring plant growth

• Understanding cell structures

• Studying chemical reactions

Which part of the cell is labeled 'i' in the animal cell?

• Cell wall

• Cell membrane

• Cytoplasm

• Nucleus

Which part of the cell is labeled 'iii' in the animal cell?

• Vacuole

• Cell membrane

• Cytoplasm

• Nucleus

How can you identify a plant cell from the given diagrams?

• Presence of a cell membrane

• Presence of a cell wall

• Presence of a small vacuole

• Absence of a nucleus

What is one reason a cell is identified as a plant cell?

• It has a flexible membrane

• It has a large vacuole

• It lacks a cell wall

• It contains chlorophyll

What is a key difference between the cell membrane and the cell wall?

• Cell membrane is found only in plant cells

• Cell wall is present in animal cells

• Cell wall is made of cellulose, cell membrane is not

• Cell membrane is rigid, cell wall is flexible

Which statement is true about the cell membrane?

• It is flexible

• It is flexible

• It is only present in plant cells

What is a common feature of both plant and animal cells?

• Presence of a large vacuole

• Presence of chlorophyll

• Presence of a cell membrane

• Presence of a cell wall
