Cells Revision Flashcards
What does an animal cell have?
nucleus, cell membrane, mitochondria, cytoplasm
What does a plant cell have?
chloroplast, nucleus, cell membrane, mitochondria, cytoplasm, vacuole, cell wall
What does a bacteria cell have?
Cytoplasm, cell membrane, cell wall, plasmid, circular DNA, flagellum
What is the nucleus function?
The nucleus contains the activities of the cell, it has DNA, which is packed into structures called chromosomes
what is the function of a circular DNA?
The DNA of bacteria found free in the cytoplasm
What’s the function of mitochondria?
It contains enzymes need for aerobic respiration, which releases energy for the cell.
What’s the function of chloroplasts?
It contains a pigment called chlorophyll, which absorbs light to provide energy for photosynthesis
What is photosynthesis?
It is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and wate
what is the function of a cell wall?
It helps strengthen the cell and provides support for the plant
What is the function of a cell membrane?
It controls the movement of substances into and out of the cell
What is the function of cytoplasm?
It’s a jelly like substance that fills the cell, where most chemical reactions occur
What’s the function of flagellum?
It’s a tail like structure that allows bacteria to move around
Vacuole
It is filled with cell sap to keep the cell rigid to support the plant
Plasmids
They are small rings of DNA that code for specific features, such as antibiotic resistance
What is the funtion of a Root hair cell
It absorbs water and minerals from the soil
