Pancreas is the gland which secretes digestive enzymes as well as hormones. It sectretes Pancreatic Juice(containing Amylase, Trypsin and Lipase) and it also secretes Insulin and Glucagon hormones.

Monecious plants have both male and female flowers rather that perfect flowers. Corn (maize) is a good example of a monecious plant species. It has two types of flowers that develop at different parts of the plant. The male flower forms at the top of the plant and is called the tassle.

Enzymes are large molecules that speed up the chemical reactions inside cells. Each type of enzyme does on specific job. Enzymes are a type of protein, and like all proteins, they are made from long chains of different amino acids. DNA is a long molecule made up of twisted strands of the bases A, T, C and G.

Xylem transports water and soluble mineral nutrients from roots to various parts of the plant. It is responsible for replacing water lost through transpiration and photosynthesis.

Phloem translocates sugars made by photosynthetic areas of plants to storage organs like roots, tubers or bulbs.

If you have a low metabolism your body does not use up energy as quickly as others so rather than using up 2000kcal in a day, your body might use 1600kcal. So most of the time even if you eat a normal amount of food your body will not use up as much. Therefore some of the food will be stored as fat which is why people with slow metabolisms might be slightly more overweight.

Taxonomic Hierarchy Categories were also introduced by Linnaeus. They are also known as Linnaean hierarchy.

 It is defined as sequence of categories in a decreasing or increasing order from kingdom to species and vice versa.

Kingdom is the highest rank followed by division, class, order, family, genus and species. Species is the lowest rank in the Hierarchy.

The hierarchy has two categories which are obligate and intermediate. Obligate means they are followed strictly and range from kingdom to species as said above. Intermediate are not followed strictly and they are added in obligate list such as subdivision, super family, super class, suborder, subspecies etc.

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase. 

The net reaction of photosynthesis is 6CO2 + 12H2O → C6H12O6 + 6H2O + 6O2 From this reaction, it is clear that to form one molecule of glucose, six molecules of carbon dioxide are required.

To answer why 12 molecules of water are required, here is the explanation

. Products of light reaction required in dark reactions to form one molecule of glucose are 12 molecules of NADPH and 18 molecules of ATP. For forming 2 molecules of NADPH from NADP+ , 2 molecules of water are required so that demand of 4 electrons and protons can be satisfied. Two molecules of water split to form1 molecule of oxygen and the respective number of electrons and hydrogen ions are also formed as shown in the reaction given below. Now for producing 12 molecules of NADPH , total 12 molecules of water are required.

The gymnosperms are a group of seed-producing plants (spermatophytes) that includes conifers (Pinophyta), cycads, Ginkgo, and gnetophytes. ... The non-encased condition of their seeds stands in contrast to the seeds and ovules of flowering plants (angiosperms), which are enclosed within an ovary.

Symplast refers to the continuous arrangement of protoplasts of a plant, which are interconnected by plasmodesmata. Apoplast consists of non protoplasmic parts such as cell wall and intracellular space. Apoplast composed of nonliving parts of a plant. Symplast composed of living parts of a plant.
