What are the structures, such as a nucleus, know as in every cell?
Are all cells the same?
Why might a cell be different?
Depending on what the cells job is and the organism they are from.
How many cells is bacteria made up of?
What is the correct scientific term for an organism with more then one cell?
A multicellular organism
What are the 2 main types of cells called?
Eukaryotic cells and Prokaryotic cells
What type of cells are plant and animal cells?
What type of cells are bacterial cells?
Do Eukaryotic cells contain a nucleus?
Do Prokaryotic cells contain a nucleus?
Where is the genetic material in Prokaryotic cells?
Floating in the cytoplasm
Which type of cell is larger Prokaryotic or Eukaryotic?
Which type of cells are simple cells, Prokaryotic or Eukaryotic?
Which type of cells are complex cells, Prokaryotic or Eukaryotic?
Roughly how big is a Eukaryotic cell?
Between 10μm and 100μm
Roughly how big is a Prokaryotic cell?
Between 1μm and 10μm
What subcellular structures do all Eukaryotic cells contain?
A nucleus(at some stage of their development), cytoplasm, a cell membrane and mitochondria
What is the function of a nucleus?
To control the activities of the cell
What two things does the nucleus contain?
The organisms genetic material, arranged as chromosomes. And instructions on how to make new cells or new organisms.
What does the genetic material in a cell determine?
The cells appearance and function
What is the plural for mitochondrion?
What happens in the mitochondria?
Cellular Respiration, enzymes, enable glucose and oxygen to react together, the reaction transfers vital energy to the organism.
What is the function of a cell membrane?
A selective barrier that controls which substances pass into and out of the cell.
What does the cell membrane also contain?
What happens in the cytoplasm?
Chemical reactions that keep the cell alive
Name the extra subcellular structures in plant cells.
A cell wall, a vacuole and chloroplast
What do chloroplast contain?
What does chlorophyll do?
Transfers energy from the sun to the plant as light, which is used in photosynthesis
Where is chloroplasts found in a plant?
Only the green parts of a plant
What is the vacuole full of?
Cell sap, a watery solution of sugar and salts
What is the function of the vacuole in a plant cell?
It helps keep the cell rigid, and this supports the plant and keeps it upright
What is the cell wall made of?
Tough fibre called cellulose
What is the function of the cell wall?
It makes the wall rigid and supports the cell
