Cell Structure B1 Paper 1 Flashcards
What is a eukaryotic cell
A eukaryotic cell is an animal or plant cell that have a cell membrane and its genetic material is enclosed in a nucleus
What is a prokaryotic cell
A prokaryotic cell is a cell which the genetic material is not enclosed in a nucleus its DNA is found as a loop in the cell and there may be one or more plasmids
What is a plasmid
Small rings of DNA
What type of cell is a bacterial cell
A prokaryotic cell
How does the size of a prokaryotic cell compare to a eukaryotic cell
They’re much smaller in size
What is the function of the nucleus
it contains genetic material it Controls activities of the cell
What is the function of the cytoplasm
It’s a gel like substance where most chemical reactions happen it contains enzymes that control these chemical reactions
What is the function of the cell membrane
Holds the cell together and controls what goes in and out
What is the function of the mitochondria
It’s where most energy is released by respiration
What is the function of ribosomes
This is where proteins are made in the cell
What is the function of the cell wall
Cell wall is made of cellulose and strengthens the cell
What is the function of chloroplasts
It contains chlorophyll which is a green substance absorbs light energy for photosynthesis
What is the function for the permanent vacuole
Filled with cell sap weak solution of salt and sugars keeps the cell turgid
What are the common parts of an animal cell
Nucleus cell membrane cytoplasm mitochondria and ribosomes
What are the common parts of a plant cell
Nucleus cell membrane cytoplasm mitochondria ribosomes chloroplast cell wall vacuole
