Cell types Flashcards
What are the two types of cells?
Prokaryotes and Eukaryotes
What is the difference between Prokaryotes and Eukaryotes?
Eukaryotic cells are complex and are all animal and plant cells whilst Prokaryotic cells are smaller and simpler e.g. bacteria
What are Eukaryotes and Prokaryotes?
Eukaryotes are organisms made up of Eukaryotic cells and Prokaryotes is a Prokaryotic cell (Single celled organism)
Animal and Plant cells: What is the Nucleus?
The nucleus contains genetic material that controls the activities of the cell
What is the cytoplasm?
Gel-like substance where most of the chemical reactions happen. it contains enzymes that control these chemical reactions
Animal and Plant cells: What is the cell membrane?
the cell membrane holds the cell together and controls what goes in and out
Animal and Plant cells: What are the mitochondria?
these are where most of the reactions for aerobic respiration take place. Respiration transfers energy that the cell needs to work.
Animal and Plant cells: What are the Ribosomes?
these are where proteins are made in the cell
Plant cells: What is the Rigid cell wall?
The rigid cell wall is made of cellulose. It supports the cell and strengthens it .
Plant cell: What is the permanent vacuole?
contains cell sap, a weak solution of sugar and salts.
Plant cell: what are the chloroplasts?
These are where photosynthesis occurs, which makes food for the plant. They contain a green substance called chlorophyll, which absorbs the light needed for photosynthesis.
What is differentiation?
The process by which a cell changes to become specialised for its job.
What does cells developing different subcellular structures mean a cell can do?
carry out specific functions
When do animal cells differentiate?
at an early stage in the cells life
What are undifferentiated cells called?
Stem cells
