400
This is the total magnification of a microscope with a 10× eyepiece and a 40× objective lens.
What is 400×?
400
This is the organelle found in large numbers in muscle tissue because of their high energy requirements.
What are mitochondria?
400
Using carrier or channel proteins this mechanism of transport moves particles down (with) their concentration gradient.
What is facilitated diffusion?
400
A cell that has swollen is most likely in this type of solution
What is hypotonic
400
This tissue transfer sugars from leaves to roots
What is the phloem
800
This is why a stain is sometimes added to a specimen before viewing it under a microscope.
What is to increase contrast?
800
This is the major structure that makes up the cell membrane
What is the phospholipid-bilayer
800
This part of the cell membrane gives the cell membrane flexibility and does not mix with water.
What is the lipid tail?
800
This is the type of solution a plant cell is in if it has undergone plasmolysis
What is hypertonic?
800
Photosynthesis occurs mostly in these cells
What are palisade cells?
1200
This is what happens to the field of view when microscope magnification increases.
What is decrease?
1200
These two organelles can be found in plant cells but not animal cells
What are the cell wall and chloroplasts
1200
This is the difference in concentration of soluted between two points
What is a concentration gradient?
1200
This is the process shown below
What is osmosis?
1200
These structures increase surface area and take up water in plants.
What are root hairs?
1600
This is the theory disproven by Pasteur, Redi, and others with experiments like swan necked flask experiment, and covered meat in a jar
What is abiogenesis?
1600
This organelle is responsible for processing lipids
What is the smooth endoplasmic reticulum
1600
This type of protein transports large molecules like glucose across the cell membrane
What are carrier proteins?
1600
This is they type of solution a cell is in where the amount of water entering the cell is equal to the amount of water leaving the cell
What is isotonic?
1600
This is the primary function of the cuticle in leaves
What is prevent water loss
2000
This is the actual length of a cell that appears 4000 um long under a magnification of 400×
What is 10 um?
2000
This is the primary purpose of ribosomes
What is processing proteins?
2000
An example of this type of active transport is bacterial cell eaten by a unicellular amoeba
What is endocytosis
2000
For this reason cells are microscopic
What is large cells cannot obtain enough nutrients, diffuse slowly, and can't easily get rid of waste?
2000
Gas exchange in leaves happens through stomata, it happens through these in stems.
What are lenticels
