The coleoptiles which tips were removed will be short and straight while coleoptiles which were cut with the tips separated by mica will be short and straight. Ceoptiles which were cut tips and separated by agar they will be tall and straight.
The set of coleoptiles which will be left in the darkness for 24 hours will be tall and bent. While the set which is in the direction of light for 24 hours will be tall and bent.
Observation is that coleoptile will grow straight if the chemical was evenly distributed and curved away from block side as if growing towards the light because dark side has the higher concentration of auxin.
62 -- The roots absorb water for the plant, and also provide it with stability, ie to keep it from falling over.64 -- Structure B is a leaf, and a leaf's main function is to take in sunlight and perform photosynthesis, which makes food for the plant.
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Answer and Explanation:
The steps for construction of the expression plasma
- STEP 1 : Introducing Notl and Hindlll confinement sites at the ends of the gene of interest by means of PCR
- STEP 2 :Digest the plasmid and DNA encoding gene with the Notl and Hindol confinement endonucleuses.
- STEP 3 : Ligate the cut plasmid and DNA fragment
- STEP 4 : Change the plasmid into E.coli for expression
- STEP 5 : Clean the protein by utilizing a column of immobilized
Answer:
The correct answer is - stomata, transpiration.
Explanation:
Photosynthesis is the process that uses light to convert CO2 and water to produce sugar and oxygen. The carbon dioxide is taken up by the little holes-like structures present on the spongy layer of the leaves called stomata. These structures are used for gaseous exchange, taken up oxygen, and releasing oxygen.
Stomata also help in releasing water vapors from the aerial parts during the process of transpiration to prevent the plants to burn in a dry environment and wind.
