Cells Flashcards
(22 cards)
Which cell is not an organelle?
a) mitochondria
b) lysosome
c) cytoplasm
d) endoplasmic recticulem
c) cytoplasm: thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins.
What structure is common to all cells?
Cell membrane.
When a large proportion of of a cells ribosomes are attached to the endoplasmic reticulum its a sign that the cell is specialised to?
Manufacture proteins for export.
What structure is most readily seen in a cell?
The nucleus.
What cells are found in animals only?
Lysosomes, centrioles.
What cells are only found in plants?
Vacuole, chloroplast, cell wall.
Define ribosome.
A cell structure that creates proteins, these proteins are used to repair damage or direct chemical processes.
The primary site of production of ATP is?
Mitochondria.
What is the storage compartment of a cell and what is its functions?
Vacuole: hold materials and water, provides pressure for support.
What part of the cell helps control what enters and leaves the cell, permits entry/ exit of dissolved materials in an animal cell?
Cell membrane.
What is passive transport?
Passive transport is the movement of materials from high concentration to a lower concentration.
What is active transport?
When a cell uses energy to transport a particle through its plasma membrane toward the side of higher concentration.
You look through a microscope and you can see a membrane bound organelles and a cell wall. You are told it is either a plant, bacterial or an animal, which one is it?
Plant cell.
What is the cell theory?
All life is made of cells, cells are made of pre-existing cells, cells are the smallest units of life.
What is a light microscope?
Uses light and glass sense to magnify a image.
Compared to water, the environment on the outside of the blood cell should be?
Hypertonic.
What would happen if you gave a patient an IV of pure water?
Their blood cells would burst.
The jelly like interior of a cell is called?
Cytosol: The cytosol is the “soup” within which all the other cell organelles reside and where most of the cellular metabolism occurs.
Cytoplasm: Cytoplasm is a term for the cytosol plus the organelles suspended within the cytosol.
How to calculate magnification on a microscope?
Multiply objective lens by ocular lens.
What part of the cell is responsible for breaking down things?
Lysosomes.
a) control centre of the cell
b) hold genetic material
c) transports lipids and carries out lipid synthesis
d) carries out majority of protein synthesis
e) transports proteins and carries out protein synthesis
f) stores food
g) digests unwanted cell parts
h) holds organelles in place
i) lets molecules in/ out of cell
j) cellular respiration
a) control centre of the cell: Nucleus
b) hold genetic material: Nucleus
c) transports lipids and carries out lipid synthesis: Smooth endoplasmic reticulum
d) carries out majority of protein synthesis: Ribosome
e) transports proteins and carries out protein synthesis: Rough endoplasmic reticulum
f) stores food: Food vacuole
g) digests unwanted cell parts: Lysosome
h) holds organelles in place: Cytoplasm
i) lets molecules in/ out of cell: Cell membrane
j) cellular respiration: Mitochondria
How to prepare a wet mount?
STEP 1
Use a flat glass slide to prepare a wet mount.
STEP 2
Suck up a few drops of your liquid specimen into a medicine dropper.
STEP 3
Pick up a flat glass slide with one hand, grasping it by the outer edges.
STEP 4
Place one drop of the liquid specimen in the medicine dropper on top of the slide. Make sure the drop goes on the centre of the slide.
STEP 5
Put down medicine dropper.
STEP 6
Use free hand to pick up a cover slip. Grasp the cover slip by the outer edges.
STEP 7
Place the cover slip on top of the slide, aligning edges with slide. Don’t press down on the cover slip.
STEP 8
Carefully slide the mount on the viewing tray of your microscope.
