Cells are the smallest unit of life. This is true.

Cells are important to the structure and function of living things. This is true.

All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.

Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.

( true )Cells are the smallest unit of life.

( true ) Cells are important to the structure and function of living things.

( false ) All organisms are made of multiple cells.

( true ) Cells come in different shapes and sizes.

Explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
