Answers
Explanation:
3 ans oxygen and water vapour
5 ans Xylem
1. Carl Linnaeus created the first hierarchical biological classification for animals in 1758 with his Systema Naturae, which Jean-Baptiste Lamarck expanded into 14 phyla by 1809.
2. Prokaryotes are the simplest, most primitive kinds of single-celled organisms.
3. Though the final product of photosynthesis is glucose, the glucose is conveniently stored as starch. Starch is approximated as (C6H10O5)n, where n is in the thousands. Starch is formed by the condensation of thousands of glucose molecules.
4. Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.
5. The cambium tissues, i.e., the cork cambium and the vascular cambium, are the only parts of a woody stem where cell division occurs; undifferentiated cells in the vascular cambium divide rapidly to produce secondary xylem to the inside and secondary phloem to the outside.
