<u>Answer:</u>
Granitic rock in the ocean floor was not included in the support for Harry Hess's hypothesis of sea-floor spreading.
<u>Explanation:</u>
- Separation of the ocean floor which leads to the expansion of the ocean is called as sea-floor spreading.
- By this process there is formation of oceanic crust that are formed by volcanic activity along with the mid-oceanic ridge.
- Rock are basaltic and dense in nature. By this theory, it is suggested that the rock which are present near the mid-oceanic ridge are younger and the rock which are far from them are older than them.
- Plate tectonic movement is the cause for the sea-floor spreading.
Deficiency of calcium in plants causes reduced internode length and crinkled leaves.
Initial signs of calcium Deficiency include localized tissue necrosis that stunts plant growth and causes young leaves to curl or have necrotic leaf margins, and terminal buds and root tips to eventually die. New growth and tissues that are expanding quickly on the plant are typically the first to be harmed.
- These include boron, copper, iron, manganese, molybdenum and zinc. Most nutrient deficiencies are caused by a lack of nutrient content in the growing medium or nutrient solution
- Plants require calcium in order to develop new growth points and root tips. Symptoms of a deficiency include decreased growth in new leaf, buds, and roots. Younger leaves curl downward and develop tip burn, which is the browning of the leaf edges and tips.

Answer: Plant Cell</h2>
Explanation:
A plant cell is the only cell that has all these characteristics. The box-like structure is due to the cell wall, the large central vacuole which helps with the rigidity of the cell, and chloroplast which contains chlorophyll for photosynthesis.
