Answers
it is made up of many cell and perform functions.
evaporation in plants in transpiration.
follow me
1)Plants are stationary thus their supportive tissue is made up of dead cells. Animals move, hence they possess living cells to provide energy for movement. Also, for the many more differences and functions in plants and animals, they are made up of different tissues.
2)Tissue is a group of cells or fluid that work together to perform a specific job in the body like cells in an organ like the kidney or heart or blood cells that carry oxygen to and waste materials from the cells in the body.
3)Totipotency is the ability of a single cell to divide and produce all of the differentiated cells in an organism. Spores and zygotes are examples of totipotent cells.
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves
4)Tracheids are the elongated cells of the xylem. They also lack protoplasm like the vessels. ... Tracheids are present in all vascular plants whereas vessels are confined to angiosperms. Tracheids are thin whereas vessel elements are wide
