Introduction to Cells (randomized) Flashcards
What is the purpose of the long axons found within nerve cells?
It is along these axons that the electrical message can travel
In plant cells, what are the two roles of the vacuole?
- Providing support for the cell shape 2. Storing sugars
In both plant and animal cells, respiration takes place in specialised structures within the cytoplasm called what?
Mitochondria
Which cells are specialised in that they have branched endings called dendrites, which is so that they can communicate with lots of other cells of the same type?
Nerve cells
In both plant and animal cells, the cytoplasm is the site of what type of activity?
Chemical reactions
What type of cell is this, and which structure within it is indicated by the arrow?
Plant cell: Chloroplast
What type of cell is this, and which structure within it is indicated by the arrow?
Plant cell: Vacuole
In both plant and animal cells, what are the two functions of the cell membrane?
- It acts as the gatekeeper and controls what enters and exits the cell. 2. It enables neighbouring cells to stick to one another
Which structure in a white blood cell has a characteristic shape, and what is this shape?
The nucleus is characteristically lobed
What name is given to the long projection of a nerve cell along which the electrical message can travel?
Axon
What is the special feature of nerve cells, what is this feature called, and what is the reason for this feature?
They have branched endings called dendrites, which is so that they can communicate with lots of other nerve cells
In both plant and animal cells, what is the location of the cell membrane?
It is the border of the cell
In plant cells, which substance (which fills a specific structure) enables plant cells to absorb light so it can be used in photosynthesis?
Chlorophyll
What type of cell is this?
Plant cell
Which specialised cells can be identified by the characteristic lobed nucleus?
White blood cells
In plant cells, with which chemical are chloroplasts filled?
Chlorophyll
Which structure in a white blood cell is flexible, and what is the function of this flexible structure?
A flexible cytoplasm, so that they can engulf pathogens in a process called phagocytosis
What type of cell is this, and which structure within it is indicated by the arrow?
Animal cell: cell membrane
Which specialised cells enable us to fight infections?
White blood cells
What type of cell is this?
Animal cell
