what properties do animal cells have?
cell membrane, nuclues, cytoplasm, mitochondria
1 of 18
what proerties do plant cells have but animal cells dont have?
cell wall, central vacuole, chloroplasts
2 of 18
what is the role of the large central vacuole?
it contains cell sap, which helps to keep the plant cell rigid
3 of 18
what proerties do bacteria have?
plasmid DNA, cell wall, flagellum, chromosomal DNA
4 of 18
what are the four different bases?
Adenine, Thymine. and. Cytosine, Guanine
5 of 18
how are the base pairs held togther?
with weak hydrogen bonds
6 of 18
what is a gene?
it is a short piece of DNA that codes for a specific protein.
7 of 18
mitosis happens between what cells?
cell divison which happens in body cells, any cell apart from those that produce gametes.
8 of 18
name the three things to remember when talking about mitosis
makes two cells which are identical, diploid ( means double chromosnes )
9 of 18
what is Meiosis?
its when a diploid cell divides to produce haploid gametes
10 of 18
what are clones?
clones are organisms that have identical genes
11 of 18
what does protein synthesis consist of?
TRANSCRIPTION which takes place in the nucleus and TRANSLATION which takes place in the cytoplasm when the mRNA strand attaches to a ribosome.
12 of 18
what are enzymes?
Catalysts
13 of 18
what is the equation of photosynthesis?
carbon dioxide + water ----- glucose + oxygen
14 of 18
what is osmosis?
it is the net movement of water molecules from a region of higher concentration to a region of their lower concentration through a partially permeable membrane
15 of 18
what is the blood made of?
plasma ( 55% )red blood cells ( 45% ) white blood cells and platelets (
16 of 18
what does a biconcave shape of a red blood cell mean?
it means it has a larger surface area, meaning its easier for oxygen to diffuse into and out of the cell.
17 of 18
what do Prebiotics contain?
high levels of oligosaccharides
