substances inside cell. There is more water inside cell than outside. Cells in hypertonic solutions experience osmosis in which water moves through membrane to outside of cell. Ex: In plant cells, membrane and cytoplasm shrink away from cell wall and plant wilts. In animal cells, the pressure decreases and the cells shrivel.
The t-cells are processed in this gland as represented by the “t”. Macrophage – Removes foreign materials and dead or dying cells in the body; also attracts t-cells to foreign organisms. A scavenger. Helper T-Cells – Identifies foreign cells in the body; stimulates other cells to fight infection. Killer T-Cells –
active transport is especially important in maintaining ion concentration in cells and between cells. Carrier proteins first binds with a particle of the substance to be transported. Carrier protein must be a similar shape that fits the molecule or ion that it is binding to.
