Cell Structure Flashcards
Plants need mitochondria
True
Outline how scientists uses a coverslip
Lower at a 45° angle
Why is a coverslip used
To protect the objective lens
Do prokaryotic cells contain a nucleus
No
The ribosomes of the cell contain the chromosomes
True
Why are stains added to the cells
To make the nucleus visible
How to calculate magnifying power of microscope
Multiply the power of the eyepiece by the power of the objective lens
How to alter amount of light on specimens
Adjust the diaphragm
Name two processes of molecules moving through cell membranes
Active transport
Diffusion
Suggest a reason why the organelle involved in aerobic respiration is found in different amounts in different cells
Different cells need different amounts of energy
What term is used to describe cells with a nucleus
Eukaryotic
Name of cells without nuclei
Prokaryotic
Name a organelle that contains a genetic material
Mitochondria
How did you transfer animal cells to the slide
Using a cotton swab on the inside of the cheek onto the slide
Diagram of cells through compound microscope
[diagram of simple cell only labelled with nucleus, cytoplasm, membrane]
Functions of cell membranes
It is semi-permeable
Gives some support to cell
Function of nuclear pores
Control the movement of substances into and out of nucleus
Function of nucleus
Genetic material
Make ribosomes
Function of mitochondria
Respiration makes ATP (ENERGY)
Pigment found in chloroplast
Chlorophyll
Function of cell wall
Acts as skeleton
Gives rigidity to cell
Functions of Vacuole
Gives turgidity and shape
Contains sap
