•All cells come from pre-existing cells
•All living orginisms are made up of 1 or more cells
•The cell is the basic unit of life

I believe these are the correct answers
Answer:
Chloroplasts are the ’solar energy plants’ of a cell – they convert light energy into chemical energy
This chemical energy may be either ATP (light dependent) or organic compounds (light independent)
Only photosynthetic tissue possess chloroplasts (e.g. is present in leaves but not roots of plants)
Chloroplasts are thought to have once been independent prokaryotes that were internalised by eukaryotes via endosymbiosis
They have a double membrane structure (due to vesicular coating as part of the endocytotic process)
They have their own DNA (circular and naked) and ribosomes (70S)
Their metabolic processes are susceptible to certain antibiotics
The structure of the chloroplast is adapted to the function it performs:
Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation
Grana – thylakoids are arranged into stacks to increase SA:Vol ratio of the thylakoid membrane
Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption
Stroma – central cavity that contains appropriate enzymes and a suitable pH for the Calvin cycle to occur
Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency

Answer:
Incomplete dominance is a type of interaction takes between two different alleles of a gene in which one allele can not express itself completely over the other allele.
It results in the production of third phenotype which is usually the intermediate of the two parental traits.
For example, when plant bearing red colored (dominant trait) snapdragon flower is crossed with the plant having white (recessive trait) flowers, it resulted in the production of the plants with pink flowers (intermediate of red and white).
When pink flowered plants were crossed they resulted in the production of plants with three types of phenotype.
The genotype and phenotype ratio were same: 1 (RR, red) : 2 (Rr, pink) : 1 (rr, white).
