Answer from: michaelFTP

Option A

Explanation:

Vascular Tissue System is composed of complex tissues which are made up of more than a single type of cell. These types of tissues are identified in vascular plants.

The basic units of Vascular tissues are Xylem and Phloem. They are known as the transport tissues and help in the transportation of water, minerals and nutrients in the plants.

Xylem is responsible for the transportation of water and minerals from plant roots to its stems and leaves. Phloem is responsible for the transportation of nutrients like organic sugars, amino acids, hormones in plants.

Therefore, the correct answer is "Option A".

Answer from: Quest

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
