Answer
To draw a labelled diagram of an animal cell, include the following components:
Cell Membrane - The outer boundary of the cell.
Cytoplasm - The gel-like substance inside the cell.
Nucleus - The control center containing genetic material.
Mitochondria - The powerhouse of the cell.
Endoplasmic Reticulum - Involved in protein and lipid synthesis.
Ribosomes - Sites of protein synthesis.
Golgi Apparatus - Modifies and packages proteins.
Ensure to label each component clearly.

Answer
The electron microscope provides greater detail than a light microscope due to its higher resolving power, allowing visualization of cellular structures at a much smaller scale.

Answer
Selective Permeability - The cell membrane controls what enters and exits the cell, allowing essential nutrients in while keeping harmful substances out.
Structure and Protection - It gives the cell its shape, supports the cell's integrity, and protects internal structures.

Answer
The nucleus has many pores to allow the passage of molecules such as RNA and proteins in and out of the nucleus, facilitating communication and regulation of cellular activities.

Answer
Cell Wall - Plant cells have a rigid cell wall, while animal cells only have a cell membrane.
Chloroplasts - Plant cells contain chloroplasts for photosynthesis, whereas animal cells do not.
