Sorry I'm not going to do your homework for you, that won't help you at all, but here are some hints:
1. Catalysis
2. Signal Transduction
3. Solar energy
4. look up osmosis- actually if you type hypotonic into your search that should explain it, but don't forget plants have a cell wall.
The other answers are all explained if you read up about cellular respiration.
Hint: What is produced by respiration and what is used up? If you are A level then you will want to read about the different stages (glycolysis, krebs cycle, and electron transport chain).
Caution some of the answers people have given you are wrong, you need to look it up, before you'll know which ones are right.

1. Enzymes - are proteins that accelerate, or catalyze, chemical reactions. In these reactions, the molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules: the products. Almost all processes in the cell need enzymes in order to occur at significant rates. Since enzymes are extremely selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
3. Sunlight is an example of SOLAR energy.
4. The cell is the basic unit of life.
