Packing of ions in salts. Which is usually larger, negative (anions) or positive (. cations. ) ions?. Construct binary salts in lattice with anions usually occupying positions in unit cell and . cations. Cell. Regarded as the basic structural and functional unit of life.. Cell is a mass of cytoplasm enclosed by a plasma membrane consisting of certain organelles besides the nucleus or nuclear material, capable of self replicating.. a hierarchy of life from cells to ecosystems.. HIERARCHY OF LIFE. HIERARCHY OF LIFE. Cell: smallest functional unit of life. Ex. Heart cell (cardiac muscle cell). Tissue: made of similar cells that have the same function. Basic Vocabulary. Biology -The study of living things. Biotic -A living organism. Abiotic -A non-living organism. How were cells discovered?. Robert -used the first microscope to view Hooke thinly sliced cork cells. . Biology: Science of Life What do Biologists do?

Live in a Cycle. Chapters 12, 13, 16, 17. Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. Presented by. Dr . Sanjoy. Deka. PLASMA MEMBRANE OR CELLMEMBRANE. Points to be discussed…. Nature of plasma membrane. Movement of substances across plasma membrane. Diffusion and osmosis.
