Characteristics of living cells

Cells are the basic units of living things. The characteristics of living cells include:

i. Growth and development. Cells usually grow up to given sizes and stop growing. Proteins are involved in the growth of cells as they attach to the plasma membrane and direct cell growth without initiating cell division. Cells cease growing after the cell membrane in the cell touches other cell membranes.
ii. Living cells undergo cellular reproduction. Living cells duplicate for procreation in unicellular organisms, while multicellular organisms replace old cells and cause tissue growth.
iii. Respiration. Living cells break down nutrient molecules to release energy used in the cell.
iv. Living cells undergo movement. Cell movement depends on the activity of the actin filaments in the cytoskeleton.

v. Homeostasis. Living cells control the amount of water getting in and out to maintain a stable environment. Cell membranes help in the regulation of the environment by controlling substances.
vi. Cells can detect stimuli and respond to the stimuli.
