Explanation

Within the ovule of Pinus, a megaspore mother cell undergoes meiosis, resulting in the production of four haploid megaspores.

However, only one of these megaspores survives and develops into the female gametophyte. 

Explanation

This pathway refers to the movement of water through the cell walls and the spaces between cells, essentially the non-living parts of the plant tissue. 

Explanation

 The botanical name for potato is Solanum tuberosum L..

It is a tetraploid species within the nightshade family, Solanaceae. 

Explanation

A landscaper's work encompasses creating and maintaining outdoor spaces,

Including gardens and other outdoor areas, using materials like wood and iron. 

Explanation

Explanation

Agrobacterium tumefaciens is a bacterium commonly used to introduce foreign genes into plants, creating transgenic plants like golden rice.

It naturally transfers DNA into plant genomes.

Explanation

The exchange of parts of non-sister chromatids of homologous chromosomes during meiosis is called Crossing over. 

During meiosis, homologous chromosomes pair up and "cross over," exchanging genetic material between their non-sister chromatids, resulting in new combinations of alleles. 

Explanation

In angiosperms (flowering plants), the endosperm is a triploid (3n) tissue that provides nourishment to the developing embryo.

It is formed during double fertilization, where one sperm nucleus fuses with the egg cell to form the zygote, and another sperm nucleus fuses with two polar nuclei in the embryo sac to create the triploid endosperm.

This triploid nature is a key characteristic of angiosperms and distinguishes them from gymnosperms, where the endosperm is haploid. 

Explanation

The Sequoia, specifically the coast redwood, is the tallest gymnosperm.
