Nat5 Biology Unit One Cell Biology Key Area 1 Cell Structure Flashcards
What is the function of a Cell Wall?
Supports, strengthens, protects and maintains the shape of the cell
That are found in plant,fungal and bacterial cells
What is the function of Mitochondria?
They are the sites of aerobic respiration
They are found in plant, animal and fungal cells
What are the function of the Chloroplasts?
They are the sites of photosynthesis
They are found in some plant cells
What is the function of a Cell Membrane?
It controls entry and exit of substances to the cell (it’s like a bodyguard)
It has a Selectively Permeable Membrane
The are found in plant, animal,fungal and bacterial cells
What is the function of a Sap Vacuole?
It stores water, sugars and salts
They are found in plant and fungal cells
What is the function of a Nucleus?
Controls many of the activities of the cell. Stores genetic information
They are found in plant animal and fungal cells
What are the function of the Ribosomes?
Sites of protein synthesis
They are found in plant, animal, fungal and bacterial cells
What are the function of Plasmids?
They are the code for the synthesis of a few proteins not coded for by the nucleus
They are found bacterial cells
What is the function of Cytoplasm?
It is the site of biochemical reactions
It is found in plant, animal, fungal and bacterial cells
How many micro meters are in a millimeter?
1000
Do bacterial cells have membrane-bound organelles?
No therefore they do not have a ‘true’ nucleus. The DNA of bacteria is found within the cell’s cytoplasm
What cells do have membrane-bound organelles?
Plant, fungal and animal cells
What types of cells have cell walls and what are they made of?
Plants, fungi and bacteria all have cell walls
Plant cell walls are made of cellulose and fungal and bacterial cell walls are made of other material
What is a cell membrane made of?
Proteins and Phospholipids
