Cell Structure and Function Assessment

The video tutorial explores the basic building blocks of life: cells. It highlights the similarities and differences between animal and plant cells. The tutorial demonstrates how to collect and examine human cheek cells and onion cells using a microscope. Key features of animal cells, such as the cell membrane, cytoplasm, and nucleus, are discussed. The video also explains additional features found in plant cells, like the cell wall and vacuole, and compares these with animal cells.
