I WONDER - What Are The Different Types Of Cells?

Cells are fundamental units of life, varying in type. Animal cells lack a cell wall and have mitochondria for energy. Plant cells have a cell wall, chloroplasts, and a vacuole. Bacterial cells are simpler, without a true nucleus, and belong to prokaryota, distinct from eukaryota like plants and animals. This classification, introduced by Carl Woes in 1977, transformed biological understanding.

What is a key difference between animal and plant cells?

• Animal cells have a cell wall, while plant cells do not.
