Xylem is a type of vascular tissue that is responsible for moving water through a plant from its roots to its leaves. Columns of xylem tissue begin in the root hairs and rise all the way up through the leaves of a plant
The Cell Wall protects the cell from particles outside.
The process is called Peer-Reviewing. In Peer-Reviewing, scientists/academic peers "peer review" the work of a scientist to check for accuracy or any false information that might reduce the legitimacy of their study or change "how realistic/real" their study is.
p.s. This is also common sense because scientists make up an entire scientific community who base their scientific studies on consistency and accuracy.
Because since the species is isolated with its partners it has to find another way to multiply so it uses another animal to make a new species to stay alive
The right options are; makes food for all organisms, adds oxygen to the atmosphere, is a source of medicines and fibers, is a source of building materials and it provides animal habitat.
Photosynthesis is a process by which green plants and some other autotrophs use light energy in chloroplasts to generate carbohydrates (food) from carbon dioxide and water while oxygen is being released as a by-product. Photosynthesis is essential to all living organisms on earth because it is the main source of oxygen in the atmosphere. Photosynthesis provides animal habitat, it provides food for all organisms (directly for plants and indirectly for animals). Plants and trees produce their foods through photosynthesis and are used as medicines and fibers, and as building materials.
