level questions: Topic 1 1: Prokaryotic and Eukaryotic cells

QuestionAnswer
What is a cell?The basic unit of life
What subcellular structures are found in the animal cell?Nucleus, Cytoplasm, Cell Membrane, Mitochondria, Ribosomes
What does the nucleus do?Contains genetic material that controls the cell's activity
What does the cell membrane do?Holds the cell together, is semi-permeable to allow certain substances to go in and out of the cell, and is a barrier that stops the cytoplasm seeping out
What does the mitochrondria do?This is the powerstation of the cell and releases energy from glucose in aerobic respiration
What does the ribosome do?It is used for protein synthesis.
