chapter 2 - cell biology and organization Flashcards
what is the function of mitochondrion in animal cell
generates energy through the glucose oxidation process
energy released is in the form of atp
what is the function of centriole in animal cell
form spindle fiber during cell division
what is the function of golgi apparatus in animal cell
processes, modifies, packs and transports chemicals such as protein , carbohydrate and glycoprotein
what is the function of plasma membrane in animal cell
separate contents of cell from the external environment
controls the movement of substances into and out of the cell
allows exchange of nutrients, respiratory gases and waste materials
what is the function of lysosome in animal cell
hydrolyses complex organic molecules such as protein, nucleic acid and lipid
breaks down bacteria and components of damaged cells
what is the function of nucleus in animal cell
controls all cell activities
contain DNA
what is the function of ribosome in animal cell
site of protein synthesis
what is the function of rough endoplasmic reticulum in animal cell
transports proteins synthesized by ribosomes
what is the function of smooth endoplasmic reticulum in animal cell
synthesizes and transports glycerol and lipids, and carries out the detoxification of drugs and metabolic by-products
what is the function of vacuole in plant cell
regulates osmoregulation of unicellular animals
water is absorbed into vacuole in plant cell and the cell becomes turgid
what is the function of chloroplast
absorbs sunlight and convert it to chemical energy to photosynthesis
what is the function of cytoplasm
acts as a medium where biochemical reactions occur
what is the function of cell wall
maintains shape of cell
provides mechanical support to plant cells
differences between plant and animal cells (6m)
plant: has fixed shape
plant: has cell wall
plant:
name examples of unicellular organisms
amoeba, protozoa
