B1 Cells Structure And Transport. Flashcards
Name everything in an animal cell
Cell membrane, Ribosomes, Mitochondria, Cytoplasm, Nucleus.
Name everything in a plant cell
Cell membrane, Ribosomes, Cellulose, Cell wall, Mitochondria, Cytoplasm, Large permanent vacuole, Chloroplast, Nucleus
Name the parts of a microscope.
Eye piece lens (x10), Objective lens (x10) (x20) (x40), Clips, Stage, Coarse focus wheel, Fine focus wheel, light source, Base.
Name the parts of a prokaryotic cell
Cell membrane, Slime capsule, Cell wall, Plasmids, flagella, DNA (one circular chromosome), cytoplasm, small ribsome.
- features that are not always preasent.
Name some eukaryotic cells.
Plant, animals, fungi
Name some red blood cell adaptations
Biconcave shaped disc
No nucleus
Contains a protine called haemoglobin that binds oxygen molecules.
What are red blood cell functions
To transport oxygen around the body
Name some sperm cell adaptations
Streamed line to help glide through the body
It has a tail to help it swim easier.
Name the sperm cells function
The function is to fertilise the egg to create a fetus
Name some nerve cell adaptations
Its long
The axon is insulated to protect it’s self
What is the nerve cell function
Its function is to send signals from the brain all over the body
Muscle cell adaptations
Layer to strengthen from tears
Strong and flexible to keep it in place
What is the muscles function
To help move bones in the body
What are the adaptations of a root hair cell
Hamer like so it can stay without having to move
String to it does not tear
What is the function of the root hair cell
Block entry of particals getting in the body
What are some xylem cell adaptations
Strong and stiff to last against damage
One way system to make sure that noting gets clotted.
What is the function of the xylem.
To transport water and minerales all over the body
What are some pholem cell adaptations
Cylinder like to protect organic molucals in side along with its layers.
Two way system to speed things up
What is the function of phloem cells
To transport organic molicules through the body
What are some adaptions of Photosythetic cells
Sturdy rectangle witha fixed shape to thanks to the cell wall use to hold protine for the plant
What are some of the functions of photosynthectic cells.
To create photosysthsis to help create protine
Define diffusion
A high concentration of particles to a low concentration.
Define net
Genral movement in or out.
What factors affect diffusion rates
Temperature
Increase the gradient
Shorten distance
If tea was placed in hot water and cold water which would diffuse quicker
Hot water due to more energy.
What is a solute
A subastance in a solution
What is a concentration gradient
The diffrence between two areas of concentration
What is gas exchange
The diffusion of oxygen and carbon dioxide in opposite directions in the lungs
What is a diffrent word for dilute in red blood cells
Hypotonic
What is another word for a concentrated solution in red blood cells
Hypertonic
What is lysis in red blood cells
The deconstruction of the blood cell when it expands
What is crenatium in red blood cells
When it shrinks
What is a word for a even solution
Iscetonic
What is falccid
Drooping or inalastic through lack of water
What is turfid
Swolen or conjested cells
What is plasmolysis
Osmosys in plants
What are the stages of plasmolysis
- Normal cells
- Inciplent plasmolysis
- Evident plasmolysis
- Final plasmolysis
When does osmosis occur
What water from a dilute solution moves to a concentrated solution to a parshly permiable membraine
What is the experiment to prove osmosis
The egg practical
What isnactive transport
Active transport is how minirals from watre move around in plant this happeneds against the consentration gradient
How do you find surface area
Lenth x width x number of sides
How do you find the volume
Length x width x hight
