To identify: The structures which is common to all four major plant groups: Vascular tissue, flowers, seeds, cuticle, and pollen.
Introduction: The vascular tissues are found in leaves, branches and stems. The cuticle is layer of waxy material which prevents the water transpiration and also protects the aerial parts of the plant.
Explanation of Solution
The cuticle is a waxy layer found in all vascular tissues. The transportation of water from the roots to the different parts of the plant is done because of this cuticle layer majorly present in terrestrial plants. The terrestrial plants are more exposed to the sunlight which may increase the transpiration process in plants.
This transpiration process is controlled by the cuticle that prevents the loss of water during high temperature. The cuticle is a layer of protection on pollen grains and seeds. This layer prevents the decaying of seeds and pollen grains even in extreme temperatures.
Out of all, the cuticle is present in the vascular tissues, flowers, seeds, and pollen. This cuticle is a layer of wax that prevents the transpiration of water.

PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
