Cards in this deck (23)
- 1Identify the functions of the nucleus.Controls cell activity
Contains genetic material. - 2What is a type of eukaryotic cell ?animal or plant cell.
- 3what is the function of the mitochondria?an organelle where aerobic respiration takes place.
- 4what is an organelle?Specialised structures found within a living cell.
- 5What is the function of a chloroplast?a plant organelle where photosynthesis takes place.
- 6What is the function of ribosomes?Protein synthesis.
- 7How can you tell the difference between the RER and the SER?RER is embedded with ribosomes
SER has no ribosomes. - 8What is the structure of the golgi apparatus?A stack of membrane bound flattened sacks.
- 9What is the function of the nucleolus ?Makes RNA and ribosomes.
- 10What is the function of the cytoplasm?The place where metabolic reactions take place.
- 11What is the structure of the cell membrane?a phospholipid bilayer, embedded with proteins.
- 12What is the function of vesicles?To transport materials around and out the cell.
- 13What are lysosomes?Specialised vesicles that contain digestive enzymes that break down waste material from inside the cell.
- 14What are centrioles?They form spindles that pull apart chromosomes during cell division.
- 15What is exocytosis?The process of vesicles fusing with the plasma membrane and secreting it's contents.
- 16What is the cell wall made of?Cellulose.
- 17What is the function of the cell wall?Protects and supports each cell and the whole plant.
- 18What is a vacuole?Membrane bound sac containing cell sap that maintain a turgid structure to the cell.
- 19What is the tonoplast?It is the partially permeable membrane of the vacuole.
- 20What is an amyloplast?A double membrane-bound sac containing starch granules.
- 21What is the function of the amyloplast?Responsible for the synthesis and storage of starch granules.
- 22What is a plasmodesmata?Channels within the cell wall of plant cells which enables transport and communication between plant cells.
- 23What are the pits inside plant cells?Pores in the cell walls of the xylem that allows water to enter and leave the xylem vessels.
