DNA structure
100
In DNA - Adenine pairs with
Thymine
100
This property allows some things to enter/leave the cell, and blocks other things from doing so.
What is selective permeability?
100
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
What is cytoplasm?
100
This organelle provides the cell with the ATP it needs to perform its functions and activities.
What is the mitochondria?
100
This occurs when particles of a substance move from where there are many particles to where there are few particles.
What is diffusion?
100
When a cell has equal amounts of water on both sides of the cell it is
isotonic
100
What is one part of the DNA structure
Answer
200
I have 2 strands
DNA
200
The part of the phospholipid that 'loves' water:
hydrophilic, hydrophobic
What is the hydrophilic head?
200
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
200
These structures are used for cell movement.
What are flagella
200
The type of diffusion that occurs when a transport protein is required to move large molecules along with the concentration gradient.
What is facilitated diffusion?
200
What happens to the size of the cell when salt water is added to it
it shrinks
200
What is one part of the DNA structure
Answer
300
This makes up the rungs of the ladder in DNA
Bases
300
Starch can not pass through a membrane because
It is too big
300
This organelle cleans up trash in the cell
What is the lysosome
300
This organelle protects the nucleus
nuclear membrane
300
This occurs when water diffuses into a cell.
What is osmosis?
300
When too much water enters the cell it is called this
Hypertonic
300
What holds the bases together in DNA
Hydrogen bonds
400
Guanine pairs with
Cytosine
400
What are the functions of the cell membrane
Support, protect and allow material in or out
400
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized (put together) here also. There are two varieties 'S' and 'R'.
What is the endoplasmic reticulum?
400
Why can plants get so tall
Because they have a cell wall
400
This term refers to the direction the particles are moving; you are either going with it or against it.
What is the concentration gradient?
400
Why don't hospitals use pure water in IV bags
Because too much water enter the cell and it woud burst
400
How many nucleotides are in this DNA strand
10
500
There are 4 differences between RNA and DNA
RNA has 1 sugar, 1 strand, is found in the cytoplasm and has the base Uracil
500
How many layers make up the cell membrane
2
500
This organelle is receives protein from the __________ and makes energy for the cell
What are ribosomes
500
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. plant cells have larger vacuoles
500
The sodium/potassium pump requires ATP to pump against the concentration gradient. This is an example of this type of transport.
What is active transport?
500
What is the term when the cell membrane pulls away from the cell wall
Plasmolysis
500
What is this a picture of
A nucleotide
