HELP ITS DUE! Pollen and seeds are the most reliable play-related evidence at archaeological sites and modern day crime scenes because they are long lasting. Relate this quality to their structure and function in living plants.

Explanation:

plant structure l: their vascular tissue allow water to be absorbed in through their plant root system, up through tubes knowns as xylem and phloem and throuht ther shoot system.

plant characteristic: their most recognizable features are stems,roots, leaves, chlorophyll, chloroplasts, and cell walls, which are made of cellulose.

plant growth: two type of meristems are apical meristem and lateral meristems.

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
