The body of a multicellular organism is organised at different levels, starting with the cell. Cells are organised into tissues, and tissues form organs. Organs are organised into organ systems and finally into an organism.
Both plant and animal cells contain common structures, though some structures are unique to each of them. The cell wall, the large central vacuole, and the chloroplast are structures found in a plant cell. The centrioles and the prominent Golgi apparatus are structures unique to an animal cell.
GROWTH AND REPRODUCTION
This program looks at sexual and asexual reproduction, starting at the cellular level, with clear explanations of meiosis and mitosis. Using a range of graphics and footage to explain biological processes, it explores various types of asexual reproduction, including fission, budding, fragmentation, spores, vegetative and artificial propagation. Sexual reproduction in animals is covered – including direct and indirect development – as well as sexual reproduction in flowering plants.
This video describes the key structures of the respiratory system and how gas exchange occurs in the alveolus.
