Describe passive transport using the words concentration and concentration gradient

Answers

Answer 1

Answer: Passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes through concentration gradients without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and osmosis.

What are pollinates?

Pollinates are to take pollen from one plant or part of a plant to another so that new plant seeds can be produced: Bees pollinate the plants by carrying the pollen from one flower to another.

Moreover, pollination is an essential part of plant reproduction. Pollen from a flower's anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.

Hence, the main reason for using hand pollination is the lack of pollinators. Worldwide we have a decrease of natural pollinators (incl. insects, mammals, birds) mainly due to the intensification of agriculture.
